Abstract

Three novel planar and star-shaped molecules containing thiophene-functionalized group and acetylenic spacers, 4-((5 ″-iodo-[2, 2′: 5′, 2 ″-terthiophen]-5-yl) ethynyl) aniline (I3TEA), 4, 4′-([2, 2′: 5′, 2 ″-terthiophene]-5, 5 ″-diylbis (ethyne-2, 1-diyl)) dianiline (3TDDA), 1, 3, 5-tris ((5-((trimethylsilyl) ethynyl) thiophen-2-yl) ethynyl) benzene (TETEB) were synthesized through Sonogashira coupling reaction. Their photophysical and ...
