36. High proton conductivity of sulfonated methoxyphenyl-containing poly(arylene ether ketone) for proton exchange membranes
A series of sulfonated methoxyphenyl-containing poly(arylene ether ketone)s (SMP-PAEKs) were synthesized via polycondensation from 2-(3-methoxy)phenylhydroquinone and other commercial monomers, followed by a postsulfonation approach under mild reaction conditions. Controlled substituted sites and the degree of sulfonation were realized by using various quantities of 2-(3-methoxy)phenylhydroquinone...

High char yield novolac modified by Si-B-N-C precursor: Thermal stability and structural evolution
In this contribution, novolac modified by CSEB ceramic precursor (B,B,B-tris[(chlorodimethylsilyl)-ethane]borazine, CSEB) was synthesized successfully. The corresponding molecular structure, chemical state and thermal property were characterized by FT-IR, Raman spectra, XPS, NMR and TGA. Meanwhile, DTA/TG/MS test was also performed to track the weight loss and gas evolution of modified novolac d...

High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
A novel high-performance polyindole containing a pyridine ring (P1)was successfully prepared by the catalyst-free nucleophilic substitution polycondensation of 4-hydroxyindole with 2,6-difluoropyridine via a C?N and C?O coupling reaction process. This semirigid polyindole P1 exhibits good thermal stability, and it can be dissolved well in common organic solvents. Fluorescent spectral studies ind...

Synthesis of High-Performance Polymers via Copper-Catalyzed Amination of Dibromoarenes with Primary Aromatic Ether Diamines
In this paper, we introduce three high-performance polymers with similar structures, poly(imino ether ketone) (PIEK)s, which are synthesized by the ligand free copper-catalyzed C-N cross coupling reaction of aryl halides and primary aromatic diamines at moderate temperature. The influence of the solvents, base, temperature, and catalyst ligands on the polycondensation reaction is investigated. T...

Design and preparation of high performance amine-based poly(ether ketone)s with strong photonic luminescence
Amine-based poly(ether ketone)s (A-PEKs), as novel high-performance functional polymers, have been obtained by the polycondensation of dibromo ketones with aromatic ether diamines via palladium-catalyzed aryl amination reaction. The structures of the polymers are characterized by means of FT-IR, 1H NMR spectroscopy and elemental analysis, the results show a good agreement with the proposed struc...

High CO2/N2 and CO2/CH4 Selectivity in A Flexible Chiral Metal Organic Framework Assembled from Difunctional Tridentate Ligand
A metal-organic framework with chiral pores and decorated imidazole and methyl groups was constructed. Upon activation, this MOF undergoes a pore contraction and shows very high selectivity for CO2/N2 and CO2/CH4, indicating a synergistic effect of dynamic pores and functional groups.
