Novel Water Soluble Fluorescent Trimethine Indocyanines Containing N-p-Carboxybenzyl Group

State Key Laboratory of Fine Chemicals, Dalian University of Technology, Dalian 116012

Received Date: 3 April 2002

Fund Project: The authors would like to thank the National Natural Science Foundation of China and The Ministry of Education of China for providing financial support for this project.

Two fluorescent indocyanine dyes containing at least one p-carboxybenzyl group on the nitrogen atoms in the hetcrocyclic rings were designed and synthesized. Their absorption maxima were 549 nm and 551 nm in water respectively. They had good water solubility and photostability.
