Abstract

The fluorescence of aminobenzonitrile clusters with solvent molecules under supersonic jet conditions is studied. The cluster size distribution is determined by time-of-flight mass spectrometry with an experimental setup that allows for mass analysis and dispersed emission spectroscopy quasi-simultaneously. For 4-dimethylaminobenzonitrile (DMABN) dual fluorescence is observed for the monomer when complexed with a minimum of five acetonitrile molecules. The single emission bands of the 4-aminobenzonitrile (ABN) and 1-ethyl-2,3-dihydro-indole-5-carbonitrile (EIN) solvent complexes are red-shifted with respect to the uncomplexed chromophores. The difference between DMABN and ABN/EIN is attributed to the population of the CT state in DMABN.
