Research Abstract

Metha-substituted phenylazomethine dendrimers were synthesized based on the molecular design for the potential programming. The metha-substituted phenylazomethine dendrimers shows a smaller reverse potential gradient than that of para-substituted model dendrimers. The dendrimers will expand the variation of the metal-assembling structure.The efficiency of the photoelectric device drastically in creases to promote the formation of radical species using shell effect of the dendrimer for the porphyrine center. We achieved sensitivity improvement of 20 times using the fourth generation dendrimer with a zinc porphyrin core. We firstly demonstrated that using the potential-programmed dendrimer promote only one-way electron transfer effectively in the interface of molecules and molecules. The results are expected to widely expand the application.
