The photocatalyst was characterized by XRD, TEM, SEM and nitrogen adsorption, and the catalyst's photoactivity was evaluated by the photodegradation of a organophosphorous pesticide DDW.

A series of novel laterally O-difluoro-substituted terphenyl chiral liquid crystals have been synthesized through a simple route based on palladium-catalyzed cross-coupling reaction.

Then we applied model to chiral compound.

Effects of the composition of chiral-achiral N-propargylamide copolymers on their secondary structures and optical activity

The electronic and steric effects of substituted groups,the structures of chiral catalysts and chiral reagents and the reaction system on optical activity of products are summarized.

Thus,four kinds of hydantoins,(5R) 5 (5 imidazolylmethyl) 3 phenyl 2,4 imidazolidinedione,(5R) 5 benzyl 3 phenyl 2,4 imidazolidinedione,(5S) 5 methyl 3 phenyl 2,4 imidazolidinedione and (5S) 5 hydroxymethyl 3 phenyl 2,4 imidazolidinedione,were prepared,which all have certain optical activity and were proved to have the expected structures by elementary analysis,IR and .
