A new vanadium-glycine complex (NH4V(Gly)3(PO4)2ldrH2O) was synthesized in hydrothermal condition and characterized by XRD, FTIR, SEM and TG-DSC techniques. The results indicate that glycine and water exist in the crystal framework as ligand coordinating with vanadium. The SEM images show that the single crystals are homogeneous in crystal size and shape, and show a good crystalline performance. The...
An intercalation nonlinear-optical (NLO) polyimide was synthesized by the ring-opening polyaddition of 4,4'-(Hexafluoroisopropylidene) diphthalic Anhydride (6FDA) and [(6-nitrobenzothiazol-2- yl)diazenyl]phenyl-1,3-diamine. Then, sol-gel technique was adopted, utilizing 3- aminopropyltriethoxysi- lane (APTES) and tetraethoxysilane (TEOS). The polyimide/silica hybrid material was obtained. The polyimide...
A series of the polyimide-silica NLO nanohybrid materials were synthesized from 3,3', 4,4'- Bisphenyltetracarboxylic (BPDA), 2,2-Bis(3-amino-4-hydroxyphen-yl) hexafluoropropane (6FHP), nonlinear optical (NLO) molecule 4-(N-2-Hydroxyethyl-N-methylamino)-4'-[(6-nitroben-zothiazol-2-yl)-diazenyl] azobenzene (HNBDA), coupling agent APTES and hydrolysate of TEOS via sol-gel process. The TEOS contents in...
