A set of N-substituted benzoperylene monoimide (BPI) fluorophores was synthesized and characterized structurally and photophysically. Condensation of benzo [ghi] perylene-1, 2- dicarboxylic anhydride in the presence of “swallow tail” alkyl amines produced fluorophores that are soluble in a range of organic solvents, highly absorbing in the near-UV (ε 334= 79 000 M–1cm–1), and fluorescent in the visible range. Photophysical behavior of the ...
