| Research Abstract |
Single molecule fluorescence spectroscopy(SMRS) was applied for elucidating fluorescence dynamics of singly isolated charge-transfer(CT) complexes formed between various monocarbazolyl and dicarbazolyl compounds as donors and 1, 2, 4, 5-tetracyanobenzene as an acceptor in various polymer films. The results of simultaneous measurements(time traces of CT fluorescence intensity and lifetime) showed three patterns of time traces. The ratio of the appearance of these patterns depended on donors and polymers. These results were discussed on the basis of the chemical structure of donors and the free volume of the host polymers. SMFS was also applied to an exciplex system and CT nanocrystals. These results were also discussed.
