Ultrafast Photoprocesses in Contact Ion Pairs of Indotricarbocyanine Dyes

摘要

The paper presents recent experimental results on the peculiarities of fluorescence and transient absorption exhibited by indotricarbocyanine dyes in solutions of different nature. The dynamics of transient absorption spectra of the molecules under study is analyzed within the framework of the concept of intra- and intermolecular vibrational relaxation and ultrafast charge transfer in contact ion pairs.
