Abstract

Tripodal ligand complexes of copper salts are described that display redoxdependent exciton coupled circular dichroism spectra. Significant spectral amplitude is observed at 400 nm in both solution and microcrystalline films. The synthesis and characterization of two new ligands and the preliminary characterization of the circular dichroism properties of their copper complexes is reported. The results constitute a significant step toward the development of molecules that can be used as on/off molecular switches.

The quarz slide (cleaned with Piranhia solution) was placed into the solution containing the dispersed material. 3.) After 10 minutes the slide was taken out, dried in an oven at 40°C for 15 minutes.Google Scholar
