Physical Properties of Cyanine–7,7,8,8,8-Tetracyanoquinodimethane Charge Transfer Complexes
A novel intramolecular charge transfer complex–cyanine–7,7,8,8,8-tetracyanoquinodimethane (TCNQ) dye was formed by grafting. The cyanine–TCNQ complex was characterized by UV–vis spectroscopy, fluorescence emission spectroscopy, and magnetic techniques. The optical properties of the cyanine–TCNQ dye,...

The cyanine–TCNQ complex was characterized by UV–vis spectroscopy, fluorescence emission spectroscopy, and magnetic techniques. The optical properties of the cyanine–TCNQ dye, which forms an intramolecular charge transfer complex, are significantly different from cyanine–I with the same basic structure. A
