High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
关键字：poly(N-aryleneindole ether); pyridine; sensor; luminescence
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...

Facile synthesis of soluble aromatic poly(amide amine)s via C–N coupling reaction: Characterization, thermal, and optical properties
关键字：aromatic poly(amide amine)s; high-performance
Aromatic poly(amide amine)s (APAAs), as novel highperformance polymers, have been obtained by the condensation polymerization of N,N’-bis(4-bromobenzoyl)-p-phenylenediamine with two different primary aromatic diamines via palladiumcatalyzed aryl amination reaction. The structures of the polymers are characterized by means of FTIR, 1H NMR spectroscopy, and elemental analysis, the results show a ...

Facile and low-cost approach towards a PVDF ultrafiltration membrane with enhanced hydrophilicity and antifouling performance via graphene oxide/water-bath coagulation
关键字：ultrafiltration membrane
Addressed herein is a facile and low-cost approach to endow hydrophobic polyvinylidene fluoride (PVDF) membranes with reliable hydrophilicity and antifouling properties. Porous asymmetric hydrophilic membranes with tunable morphology were facilely fabricated via phase inversion using an aqueous solution of graphene oxide (GO) as the coagulation bath. An increment in pore size and surface rou...

Synthesis, characterization and photovoltaic performances of D–A copolymers based on BDT and DBPz: the largely improved performance caused by additional thiophene blocks
关键字：solar cells, thiophene, copolymers
Two new low bandgap copolymers, PBDT-DBPz and PBDT-DTDBPz, were prepared, in which the only difference was the additional added thiophene bridge between the BDT donor unit and DBPz acceptor unit for PBDT-DTDBPz. In addition to the improvements of UV-vis absorption and hole mobility, the PSC based on PBDT-DTDBPz:PC71BM demonstrated a power conversion efficiency of 4.75%, much higher&nbs...
