Intimately bound coumarin and bis(alkylaminostyryl)benzene fragments: Synthesis and energy transfer

Article abstract of DOI:10.1016/j.tet.2013.01.075

A novel trichromophoric assembly was synthesized, where two molecules of 7-alkoxy-4-methylcoumarin, acting as energy donors, were linked at a fixed distance and controlled geometry to an energy-acceptor bis(alkylaminostyryl) unit. Resonance energy transfe
