Abstract

The series of rigidmeso-aminophenyl-substituted heptamethine dyes presented herein exhibit surprisingfluorescence properties, demonstrating larger Stokes shifts when compared with both structurally similar rigidmeso-chlorophenyl and linear heptamethine dyes. Based on their photophysical properties, these are ofconsiderable importance to the development of contrast agents, within biology and medicine.
