Ferrocene-Donor and 4,5-Dicyanoimidazole-Acceptor Moieties in Charge- Transfer Chromophores with p Linkers Tailored for Second-Order Nonlinear Optics

Original language description

A series of new nonlinear optical chromophores (1?15) that were comprised of ferrocene-donor and 4,5-dicyanoimidazole-acceptor moieties and various p linkers of different length were synthesized. Support for the presence of significant DA interactions inthese NLO-phores was obtained from the evaluation of the quinoid character of the 1,4-phenylene moieties and their electronic absorption spectra, which featured intense high-energy (HE) bands that were accompanied by less-intense low-energy (LE) bands.The redox behavior of these compounds was investigated by cyclic voltammetry (CV) and by rotating-disc voltammetry (RDV); their electrochemical gaps decreased steadily from 2.64 to 2.09 V. In addition to the experimentally obtained data, DFT calculationsof their absorption spectra, HOMO/LUMO levels, and secondorder polarizabilities (b) (2w,w,w) were performed. A structure?property relationship study that was performed by systematically altering the p linker revealed that the intramolecu
