A straightforward modular approach to NLO-active beta-amino vinyl nitrothiophenes
Secondary amines add very efficiently to 2-ethynyl-5-nitrothiophene to give beta-amino vinyl nitrothiophenes, a novel class of push-pull chromophores. According to first HRS measurements these highly solvochromic compounds with relatively short dipole axes display remarkably high static first hyperpolarizabilities = 29-31 x 10(-)(30) esu.
