Title: Intermolecular intersystem crossing in single-molecule spectroscopy: Terrylene in anthracene crystal
Abstract: We present a spectroscopic study of terrylene in anthracene crystals at the ensemble and single-molecule levels. In this matrix, single-molecule fluorescence is reduced by three orders of magnitude. Correlation measurements allow us to identify a new relaxation channel, matrix-enhanced intersystem crossing. This process starts with a singlet-to-triplet energy transfer from guest to host, after which the triplet exciton is transferred back to the guest. The intermolecular intersystem crossing is expected whenever the lowest triplet state of the host is located between the lowest singlet S1 and lowest triplet T1 excited states of the guest. It must be considered when searching for new host-guest systems for single-molecule spectroscopy.
