Abstract
Ultrafast relaxation dynamics of 13,14-diphenyldibenzo[b,j][4,7]phenanthroline (DBP3) thin film were studied with various time-resolved spectroscopic techniques including TCSPC, fluorescence up-conversion and fs transient absorption spectroscopy. Two fluorescence emission bands originating from S1 state of phenanthroline and intramolecular benzene excimer were observed. Intramolecular benzene excimer fluorescence lifetime is suppressed by a factor of ten in thin film as compared to diluted solution while conversely the S1 fluorescence lifetime of DBP3 is enhanced in film.
期刊介绍:
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
