摘要：

A laser-induced fluorescence study of N-(4-cyanophenyl)carbazole and the 1:1 complex between carbazole and benzonitrile is presented. The electronic origin of the hydrogen-bonded complex was found to be shifted bathochromically to a greater extent than that of the covalently linked molecule. In both cases the conformation of the ring systems appears to be perpendicular in both ground and first excited electronic states and the spectroscopy can be explained in terms of a perturbed carbazole chromophore. No evidence of emission from a twisted intramolecular charge-transfer slate from N-4-cyanophenyl carbazole was found. in contrast to solution-phase results.
