Dendritic poly(L-lysine)s combining clusters of zinc(II) porphyrins and methyl viologens for a photoinduced electron transfer system

摘要

We previously reported the synthesis of dendritic poly(L-lysine)s containing a large number of free base-and Zn(II)-porphyrins near the surface in scamble fashion [1],hemisphere fashion [2] and double strate fashion [3].These dendrimers showed fluorescence energy transfer from Zn(II)-porphyrin to free base-porphyrin with 85%,43% and 90% efficiencies,respectively.
