A novel autocatalytic phthalonitrile monomer [4,4′-(((((oxy-bis [4,1-phenylene]) bis (azanediyl)) bis (methylene)) bis (2-methoxy-4,1-phenylene)) bis (oxy)) diphthalonitrile, OPD] is obtained by nucleophilic substitution of 4-nitro-phthalonitrile and bisphenol compound [4,4′-(((oxy bis [4,1-phenylene]) bis (azanylylidene)) bis (methanylylidene)) bis (2-methoxyphenol)]. Bisphenol compound is a reductant with secondary amine groups of Schiff base derived from the reaction of vanillin and 4,4′-diaminodiphenylether. The OPD monomer has a self-catalytic polymerizing reaction. OPD monomer has good processability, and the processing window was 130°C. Moreover, OPD polymer [poly(OPD)] shows higher glass-transition temperature (345°C). The 5% and 10% thermal decomposition temperatures of poly(OPD) and char yield at 800°C are 407, 451°C, and 69%, resp. To further improve the properties of poly(OPD), the OPD monomer was modified by multi-functional fluorene-based benzoxazine monomers (MFFB) due to their excellent reaction activities. The results showed that OPD/MFFB systems had high reaction activities. The similar thermal stabilities between OPD and MFFB can give stable and excellent thermal stability to the poly(OPD/MFFB). Compared with poly(OPD), the Tg values of poly(OPD/MFFB) were significantly increased, and their stiffness values were reduced. The tensile, flexural, and impact properties for poly(OPD/MFFB) were improved significantly.

Wang, Ting;Dayo, Abdul Qadeer;Wang, Zi-long;Lu, Hui-min;Shi, Cheng-yu;Pan, Zhong-cheng;Wang, Jun;Zhou, Heng;Liu, Wen-bin research published 《 Novel self-promoted phthalonitrile monomer with siloxane segments: synthesis, curing kinetics, and thermal properties》, the research content is summarized as follows. A new kind of autocatalytic phthalonitrile monomer (PN) containing siloxane segments and secondary amino groups (TSOP) was synthesized from bisphenol compound and 4-nitrophthalonitrile using K2CO3 as a catalyst. Bisphenol was a reducing agent with a Schiff base containing secondary amine groups produced by the condensation reaction of 1,3-bis(3-amino-propyl)-1,1,3,3-tetra-Me disiloxane and vanillin. The curing behaviors, kinetics, and thermal and thermomech. characteristics of the TSOP monomer and its polymer (poly(TSOP)) were analyzed by torque rheometry, differential scanning calorimetry (DSC), Fourier transformation IR spectroscopy (FTIR), thermogravity anal. (TGA), and dynamic thermal mech. anal. (DMA), resp. The non-isothermal curing kinetics results indicated that the cyano addition polymerization of the TSOP monomer was a self-catalytic reaction. The active hydrogen atoms from the secondary amino groups in the TSOP monomer could accelerate the crosslinking polymerization reaction of cyano groups, producing a decline in the curing temperature and a rise in the curing rate. Meanwhile, the TSOP monomer had a low melting temperature (77°C) and a wide process window (110°C) due to the introduction of flexible siloxane segments. The poly(TSOP) having phthalocyanine and a triazine ring exhibited a higher glass transition temperature (Tg) of 348°C and good thermal stability.

Tundidor-Camba, Alain;Tagle, Luis H.;Terraza, Claudio A.;Rivera, Jorge;Coll, Deysma;Ortiz, Pablo A. research published 《 Tri-functional oligomeric polyesters prepared from new dicarboxylic acids containing several amino acids residues by Higashi methodology: synthesis, characterization, and study of solubility and thermal behavior》, the research content is summarized as follows. Abstract: The synthesis of polyfunctional aliphatic oligomeric polyesters (poly(ether-imido-esters); PEIEs) containing several amino acid residues is described, and their thermal properties and solubility behavior were studied. The new sym. monomeric dicarboxylic acids were synthesized using 4-nitrophthalonitrile as starting material, which reacted with bisphenol-A or bis(4-hydroxyphenyl)diphenylmethane. Then, the tetranitrile derivatives were hydrolyzed to the tetracarboxylic acids and dehydrated to the resp. dianhydrides. Finally, these compounds reacted with the amino acids glycine or L-alanine to obtain the aliphatic dicarboxylic acid monomers. PEIEs were obtained by Higashi methodol. from these monomers and bisphenol-A, characterized by elemental anal., NMR and IR, and the results were in agreement with the structures. The materials were soluble at 25°C in several aprotic polar organic solvents and some in CHCl₃ and THF. In agreement with the viscosity and SEC results, PEIEs were oligomers with d.p. of four and six, and Mw and Mn between 7370-9790 g/mol and 3680-4850 g/mol, resp. The samples showed low T_g values (124-160°C), associated with important structural flexibility promotes by dicarboxylic acid monomers. Despite this, this parameter depended of the aminoacidic residue nature in the sense that when the volume of it increased, the T_g also increased due to a decrease in the free rotation that neg. affects the segmental movements of the chains. This effect was also observed when the side groups of the diphenol moiety of the dicarboxylic acid monomers increase from Me to Ph. The recorded TDT_10% values from the TGA anal. (334-457°C) do not allow to consider these samples as thermoset materials. In this sense, it was possible to observe an average increase of 8-13°C and 23-28°C when the lateral group volume of the amino acid residues and of the diphenol moiety are increased, resp.

Wang, Chongchong;Li, Yanqing;Yang, Weijie;Zhou, Lin;Wei, Shaohua research published 《 Nanozyme with Robust Catalase Activity by Multiple Mechanisms and Its Application for Hypoxic Tumor Treatment》, the research content is summarized as follows. Utilizing catalase-mimicking nanozymes to produce O₂ is an effective method to overcome tumor hypoxia. However, it is challenging to fabricate nanozymes with ultrahigh catalytic activity. Palladium nanosheet (Pd NS), a photothermal agent for photothermal therapy (PTT), has superior catalase-mimicking activity. Here, titanium dioxide (TiO₂) is used to modify Pd NS (denoted Pd@TiO₂) by a simple one-step method to improve its catalytic activity about 8 times. The enhancement mechanism′s fundamental insights are discussed through experiments and d. functional theory calculations Next, zinc phthalocyanine is loaded on Pd@TiO₂ to form a nanomotor (denoted PTZCs) with the synergistic activities of photodynamic therapy and PTT. PTZCs inherit the catalase activity of Pd@TiO₂ to facilitate the decomposition of endogenous H₂O₂ to O₂, which can relieve tumor hypoxia and propel PTZC migration to expand the reach of PTZCs, further enhancing its synergistic treatment outcome both in vitro and in vivo. It is proposed that this work can provide a simple and effective strategy for catalytic activity enhancement and bring a critical new perspective to studying and guiding the nanozyme design.

Srivishnu, K. S.;Naresh, Madarapu;Laxmikanth Rao, J.;Giribabu, Lingamallu research published 《 Photo-induced intramolecular electron transfer in phenoxazine-phthalocyanine donor-acceptor systems》, the research content is summarized as follows. Donor-Acceptor (D-A) systems based on phenoxazine – phthalocyanine (PXZ-Pc) and phenoxazine – zinc phthalocyanine (PXZ-ZnPc) have been designed and synthesized. Both D-A systems are characterized using various spectroscopic and electrochem. techniques including in-situ methods. Optical absorption studies suggest that both Soret and Q bands of these D-A systems are hypsochromically and bathochromically shifted, when compared to its individual constituents. The study supported by theor. calculations shows clearly that there exists a negligible electronic communication in the ground state between donor phenoxazine and acceptor phthalocyanine. However, attractively, both D-A systems exhibit noteworthy fluorescence emission quenching (90-99%) of the phthalocyanine emission compared to its reference compounds The fluorescence emission quenching featured at the excited-state intramol. photoinduced electron transfer from ground state of phenoxazine to the excited state of phthalocyaine/zinc phthalocyanine. The rates of electron-transfer (kET) of these D-A systems are found in the range of 5.7 x 108 to 2.8 x 109 s^-1 and are according to solvent polarity.

Singh, Ajit Shankar;Shukla, S. K.;Mishra, Preeti;Pandey, A. K. research published 《 Synthesis and thermal evaluation of novel mono- and bis-adamantylated resorcinol-based phthalonitrile resins with enhanced solubility》, the research content is summarized as follows. Phthalonitrile (PN) resins are high-temperature-resistant thermosetting polymers which find applications in military as well as aerospace owing to their outstanding performance. At present, most of the PN resins are melt-processed and cured at high temperature via resin transfer molding owing to their poor solubility in common organic solvents. In the present, embodiment efforts have been made to change the PN resin backbone with adamantane as potential functionality. Mono- and novel bis-adamantylated resorcinols 1a and 1b have been synthesized via Amberlyst-15 solid acid resin-catalyzed Friedel-Crafts alkylation reaction, as precursor material for the synthesis of novel phthalonitrile (PN) resin monomers 2a and 2b, resp. The study includes structural and thermal characterization of resin monomers 2a and 2b along with their solubility in common organic solvents. These resins when cured to their thermosets have demonstrated thermal stability ~723 K (5% mass loss) with no glass transition temperature (Tg) up to 673 K. The resin monomers show very good solubility in industry-friendly organic solvents like acetone, Et acetate, Me Et ketone and Me iso-Bu ketone.

Pectin was used as a green support in this study to construct an efficient heterogeneous catalytic system based on the conjugation of metal phthalocyanines. To end this, pectin was first oxidized with periodate oxidant agent to effectively immobilize a tetra-amino copper phthalocyanine (Cu-PcTA) through a green, simple, and an efficient one-pot Ugi four-component reaction (Ugi-4CR). Then, the catalytic activity of the copper phthalocyanine-conjugated pectin was investigated in the CO₂ fixation reaction to cyclic carbonates. Optimum catalytic conditions were as follows: 30 mg of prepared catalyst, 3 bar CO₂ pressure, 90°C, 2 h, and TBAB as a co-catalyst. Pectin could successfully improve the catalytical properties of the Cu-PcTA over the CO₂ fixation reaction.
