Compounds were identified by UV-visible, IR, ¹H and ¹³C NMR spectroscopies. The features of the acid-base interaction and the acidity constants of the copper tetrakis(3,5-di-tert-butylbenzoyloxy)phthalocyaninate protonated forms, as well as Cu tetra(4-tert-butyl)phthalocyaninate and its ligand in the system CH₂Cl₂-100% HO₂CCF₃ were studied.

Maertens, Gaetan;Deruer, Elsa;Denis, Maxime;Canesi, Sylvain research published 《 Common Strategy for the Synthesis of Some Strychnos Indole Alkaloids》, the research content is summarized as follows. Indole alkaloids are important natural compounds with interesting bio-activities that can be found in various species belonging to the Amaryllidaceae, Apocynaceae, or Strychnaceae families. Although these compounds have different connections, substituents, and functionalities, their main core can be produced via the formation of a common functionalized tetracyclic subunit, I, which is rapidly obtained by an oxidative de-aromatization process mediated by a hypervalent iodine reagent from an inexpensive phenol containing a lactate moiety as the chiral auxiliary. A subsequent stereoselective aza-Michael addition and an intramol. Heck-type reaction lead to the formation of a common key intermediate. This approach provides a solid foundation for the further elaborations of several natural products. The asym. syntheses of (-)-strychnopivotine and the polycyclic main cores of (-)-strychnosplendine, (+)-isosplendine, and (+)-malagashanol, three other indole alkaloids, are reported.

Ma, Yao;Bruno, Nicholas C.;Zhang, Fengyi;Finn, M. G.;Lively, Ryan P. research published 《 Zeolite-like performance for xylene isomer purification using polymer-derived carbon membranes》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) have been used as precursors for the fabrication of porous carbon mol. sieve (CMS) membranes. PIM-1, a prototypical PIM material, uses a fused-ring structure to increase chain rigidity between spirobisindane repeat units. These two factors inhibit effective chain packing, thus resulting in high free volume within the membrane. However, a decrease of pore size and porosity was observed after pyrolytic conversion of PIM-1 to CMS membranes, attributed to the destruction of the spirocenter, which results in the ‘flattening’ of the polymer backbone and graphite-like stacking of carbonaceous strands. Here, a spirobifluorene-based polymer of intrinsic microporosity (PIM-SBF) was synthesized and used to fabricate CMS membranes that showed significant increases in p-xylene permeability (approx. four times), with little loss in p-xylene/o-xylene selectivity (13.4 vs. 14.7) for equimolar xylene vapor separations when compared to PIM-1-derived CMS membranes. This work suggests that it is feasible to fabricate such highly microporous CMS membranes with performances that exceed current state-of-the-art zeolites at high xylene loadings.

Ma, Yan;Ren, Kaixu;Zeng, Ziqiu;Feng, Mengna;Huang, Yumin research published 《 Highly selective sulfonated Poly (arylene ether nitrile) composite membranes containing copper phthalocyanine grafted graphene oxide for direct methanol fuel cell》, the research content is summarized as follows. To improve the performances of sulfonated poly (arylene ether nitrile) (SPEN)-based proton exchange membranes (PEMs) in direct methanol fuel cells (DMFCs), the copper phthalocyanine grafted graphene oxide (CP-GO) was successfully prepared via in situ polymerization and subsequently incorporated into SPEN as filler to fabricate a series of SPEN/CP-GO-X (X represents for the mass ratio of CP-GO) composite membranes. The water absorption, swelling ratio, mech. properties, proton conductivity, and methanol permeability of the membranes were systematically studied. CP-GO possesses good dispersion and compatibility with SPEN matrix, which is propitious to the formation of strong interfacial interactions with the SPEN, so as to provide more efficient transport channels for proton transfer in the composite membranes and significantly improve the proton conductivity of the membranes. Besides, the strong π-π conjugation interactions between CP-GO and SPEN matrix can make the composite membranes more compact, blocking the methanol transfer in the membranes, and significantly reducing the methanol permeability. Consequently, the SPEN/CP-GO^-1 composite membrane displayed outstanding tensile strength (58 MPa at 100% RH and 25°C), excellent proton conductivity (0.178 S cm^-1 at 60°C), and superior selectivity (5.552 x 10⁵ S·cm^-3·s). This study proposed a new method and strategy for the preparation of high performance PEMs.
