Paper Abstract

The excitation dynamics in indandione-1,3 Pyridinium Betaine (IPB) intramolecular charge transfer molecules in various environments was studied. By comparing the excitation properties of the IPB molecules in solution and those in the crystal form, the influence of the intermolecular interactions on the excited state dynamics is considered. Two types of excited states are revealed in the IPB crystal: the Frenkel exciton states, which cause ultrafast nonradiative excitation decay, and the intermolecular charge transfer exciton states positioned below the Frenkel states, that have a longer lifetime and are responsible for pronounced photocurrent efficiency of IPB solids.
