Research the Property of Organic Nano Gathered Based on Porphyrin
Abstract: We designed and synthesized dendritic porphyrin which brings hydrophilic groups and hydrophobic groups. Their different aggregation behaviors in aqueous solution were studied by using UV absorption spectroscopy, scanning electron microscopy (SEM) and Nanoparticle technology. Results indicated that porphyrin 1 bearing hydrophobic group can form rod-like structures introduced by H-aggregation. Porphyrin 2 containing hydrophilic moiety can form hollow spherical structures (diameter is about 340 nm) caused by J-aggregation. So we have come, by changing the the por- phyrins external substituents can be modulated by the morphology of nano-aggregates.
