摘要
Dendrimer complexes[(G-2)(4)P and (G-S)(3)P] with a porphyrin core have been prepared by self-assembling of sodium tetrakis(4-sulfonatophenyl) porphyrin with dendritic quaternary bromides (G-2 and G-3), which were synthesized by reaction of Frechet type dendritic bromides (G-2 and G-3) with triethylamine. The structure of dendrimer complexes was confirmed by H-1 NMR and element analysis. The stoichiometry rate between the dendritic quaternary bromide and porphyrin core was 4:1. Solvatochromism studies of the dendritic complexes showed that the (G-3)(4)P dendritic complex is more stable than the (G-2)(4)P dendritic complex. It is inferred that hydrophobic interactions play an important role in stabilizing these dendrimer complexes in addition to coulombic interactions. (C) 1999 Published by Elsevier Science S.A.
