N,N0-Dibutylbarbituric acid as an acceptor moiety in push-pull chromophores

International audienceTwelve novel D-p-A chromophores with the N,N0-dibutylbarbituric acid acceptor, the N,N-dimethylamino donor and a systematically extended p-linker were synthesized. The extent of intramolecular charge-transfer, structure-property relationships and nonlinear optical properties were further investigated by X-ray analysis, electrochemistry, UV/Vis absorption spectra, calculations and EFISH experiments
