摘要

Triplet-triplet absorption spectra of anthracene, phenanthrene, and naphthalene in thallium ion (Tl + )-exchanged X-type zeolites (T1X) were found to be significantly different from those of the aromatics in sodium ion (Na + )-or cesium ion (Cs + -exchanged zeolites (NaX or CsX); broad and stuctureless spectra with a small red-shift are ascribed to a triplet complex of the aromatics with T1 + . The complex formation is considered to be responsible for the enhanced intersystem crossing observed for the aromatics in T1X, and this is in contrast with the observation in CsX where a simple heavy atom-assisted intersystem crossing is operative.
