Abstract
Secondary amines add very efficiently to 2-ethynyl-5-nitrothiophene to give β-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 × 10-30 esu.Keywords
