Abstract

Abstract Carbocyanine dyes are a class of organic compounds that contain two heterocycles that act as electron donors and acceptors connected by a conjugated methine bridge. Herein the synthesis of a series of 16 novel unsymmetrical trimethine cyanine dyes is reported. Their structures were characterized by various spectroscopic techniques, and their optical properties were measured. Absorption maxima of the dyes were calculated using ...
