Wang, Taisheng;Shen, Lei;Wang, Haoxiang;Zhang, Na research published 《 A highly selective fluorescent sensor for ratiometric detection of cyanide in aqueous solution and solid states》, the research content is summarized as follows. Designing fluorescent sensors for selective detection of CN^– in aqueous and even solid states are still rarely reported due to the aggregation-caused quenching (ACQ) effect. In this paper, we report a novel fluorescent probe C-1. Due to the AIE effect, C-1 displayed obvious orange-red fluorescence with emission peak centered at 597nm in aqueous solution and solid state. Under the influence of electron withdrawing cyano and ester groups, the vinyl C=C bond was easy to be attacked by nucleophilic CN^–, which destroyed the conjugated bridge and also blocked the ICT process between the donor and the acceptor. The emission band shifted from 597 nm to 475 nm consequently. Other anions have no effect on the fluorescence of C-1. Thus, C-1 could be used as a selective CN^– sensor. The UV-visible and fluorescent measurement confirmed the interactions between C-1 and CN^–. ¹H NMR titration method further demonstrated the detection mechanism. The sensitivity and detection limit of C-1 were measured to be 5.97 x 10⁴ M^-1 and 1.2 μM resp. Due to the solid-state emission nature, C-1 immersed test strip was prepared and used as an effective test kit to detect CN ion.

A novel series of self-catalytic phthalonitrile monomers with aliphatic segments (BPAA) were synthesized via nitro nucleophilic substitution reaction of bisphenol compound and 4-nitrophthalonitrile. Bisphenol compound was reductant with secondary amine groups of Schiff base derived from the reaction of vanillin and one of the aliphatic diamine such as 1,2-ethylenediamine, 1,3-propane diamine, and 1,6-hexamethylenediamine. The curing reaction of BPAA monomers can be carried out without any catalyst. BPAA monomers showed excellent processing properties. Moreover, BPAA polymers (poly(BAPP)) showed superior thermal stabilities and higher glass-transition temperatures (T_g) (302-317°C). The 5% thermal decomposition temperatures (T₅) of poly(BAPP) and char yield (Yc) at 800°C under nitrogen atm. were 352.5-410.5°C and 61.3-66.8%, resp. To further improve the thermal stability of poly(BAPP), BPAA monomers were modified by multi-functional fluorene-based benzoxazine monomers (MFFB) due to their excellent reaction activities.

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.

Tu, Poyi;He, Xunming;Abu-Reziq, Raed;Pan, Chunyue;Tang, Juntao;Yu, Guipeng research published 《 Fluorinated covalent triazine frameworks for effective CH₄ separation and iodine vapor uptake》, the research content is summarized as follows. In this article, analogous covalent triazine framework (CTFs) were simply prepared through the trimerization of different nitrile building blocks (tetrafluoroterephthalonitrile or terephthalonitrile) under typical ionothermal conditions. We demonstrated that the fluorine contents could be simply altered by changing the comonomer compositions Introducing fluorine could adjust the pore size distribution and electron structure of the network effectively. By increasing fluorine contents, an enhanced CO₂/CH₄ selectivity up to 15.5 was presented. Addnl., electron-concentrated fluorine strengthened CH/π interactions between the polymeric matrixes and guest CH₄, offering a CH₄/N₂ selectivity up to 8.0. The obtained CTFs also exhibited noticeable iodine adsorption capacity in vapor phase (302 wt%) due to their abundance of heteroatoms and porosity. These results clearly demonstrated the promising aspect of introducing fluorine groups into the porous networks for developing efficient sorbent towards potential applications in separating methane gas or iodine vapors and also affording further insight into the development of high performance functional polymers.

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.

In this study we self-assembled the four-armed porphyrin hetero dimer capsule Cap4, stabilized through amidinium-carboxylate salt bridges, in CH₂Cl₂ and CHCl₃. The dimer capsule Cap4 was kinetically and thermodynamically more stable than the corresponding two-armed dimer Cap2. The number of arms strongly influenced their recognition behavior; guests possessing small aromatic faces (e.g., 1,3,5-trinitrobenzene) preferred residing in the cavity of the two-armed capsule Cap2, rather than in Cap4, both thermodynamically and kinetically; in contrast, large aromatic guests (e.g., 9,10-dibromoanthracene) were encapsulated predominantly by Cap4 because of favorable entropic effects. The number of arms enabled self-sorting behavior of the dimer formation; complexation studies using an equimolar mixture of the four porphyrin constituents of the two capsules revealed the quant. formation of the corresponding dimers Cap2 and Cap4. Furthermore, we examined the specific mol. recognition of Cap2 and Cap4; NMR experiments of mixtures of Cap2 and Cap4 in the presence of favorable guests for Cap2 and Cap4 revealed that these guest mols. were encapsulated selectively by their preferred hosts.
