Synthesis and characterization of novel second-order NLO-chromophores bearing pyrrole as an electron donor group

Two series of novel push-pull 1-(4-(thiophen-2-yl)phenyl)-1H-pyrroles 3-5 were designed to explore the consequence of using different electron accepting moieties linked to the thiophene at the arylthiophene bridge or to the pyrrole heterocycle which plays the role of donor group. Compound 2 showed a...
