Some of bis(N-R-salicylaldiminato)Cu-II where R = H, CH3, C2H5, and C6H5 are found to have copper chains in one direction of the crystals. These 1-d systems are hydrogen bonded with six highly polarizable dyes namely Para red, Congo red, Direct red, Bismark brown, Evans blue, and Trypan blue. The Fourier transform infrared (FTIR) spectra reveal infrared absorption edge and its modification with exciton-phonon coupling. Threshold energies for the formation of excitons with phonon emissions are observed. When exciton-phonon coupling is weak, a large number of phonon bands are observed in the edge spectrum. Free excitons are strongly bound and bound excitons are weakly bound to phonons.
