18 Striking influence of Fe2O3 on the "catalytic carbonization" of chlorinated poly(vinyl chloride) into carbon microspheres with high performance in the photo-degradation of Congo red
关键字：poly(vinyl chloride)
A one-pot approach was demonstrated to effectively synthesize carbon microspheres through “catalytic carbonization” of commercial chlorinated poly(vinyl chloride) (CPVC) microspheres by Fe2O3 at 700 °C. Without Fe2O3, a “sponge-like” carbon lump was obtained. However, after adding Fe2O3 (even 0.5 g per 100 g CPVC) into CPVC, carbon microspheres with octahedral Fe3O4 microcrystals uniformly em...

13 Catalytic carbonization of chlorinated poly(vinyl chloride) microfibers into carbon microfibers with high performance in the photo-degradation of Congo red
关键字：poly(vinyl chloride)
A simple approach was reported to prepare carbon microfibers embedded with octahedral Fe3O4 crystals (Fe/CMFs) through catalytic carbonization of chlorinated poly(vinyl chloride) (CPVC) microfibers using Fe3O4 as catalyst at 700 °C. Without Fe3O4, irregular carbon was obtained. However, after adding a proper amount of Fe3O4, carbon microfibers with uniform size were prepared. The influence of Fe3...

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...
