Rotational barriers in perylene fluorescent dyes

Langhals, Heinz ; Demmig, Stefan und Huber, Helmut (1988): Rotational barriers in perylene fluorescent dyes. In: Spectrochimica Acta Part A: Molecular Spectroscopy, Vol. 44, No. 11: pp. 1189-1193

Abstract

Rotational barriers in N-substituted perylene dyes have been determined. Phenyl substituents with tert-butyl groups in the o-position give rigid systems, whereas secondary alkyl groups cause low rotational barriers. In spite of that, fluorescent quantum yields are high in both cases. Conformations in solution are discussed.
