Heterocyclic quinol-type fluorophores. Part 1: Synthesis of new benzofurano[3,2-b]naphthoquinol derivatives and their photo-physical properties in solution and in the crystalline state

Article abstract of DOI:10.1039/b109198k

Isomeric pairs of novel benzofuranonaphthoquinol-type fluorophores (2a-2c and 3a-3c) have been synthesized and their absorption and fluorescence characteristics in solution and in the crystalline state have been studied. Big differences in the absorption
