Intramolecular Energy Transfer. Illumination into the rutheniumii complex is accompanied by rapid intramolecular energy transfer from the metal to ligand charge transfer mlct triplet to the lowest energy ππ triplet state localized on one of the porphyrin subunits. Intramolecular energy transfer is very fast whereas intermolecular energy transfer is relatively slow.
In order to study the effect of ict on two photon absorption tpa and excited state absorption esa three chalcone derivatives 1 2 and 3 with different electron pushpull systems were designed and synthesizedthe ict performance of these. The rate of energy transfer depends on the structure of the dual dye system and decreases as the centre to centre separation increases. Chemical reviews 2017.
Direct evidence of solvent polarity governing the intramolecular charge and energy transfer.
Energy transfer in the present system can be described as occurring via a through space energy transfer mechanism. Energy transfer between polystyrene donor and 25 diphenyloxazole ppo species incorporated as intramolecular energy traps has been studied by time resolved luminescence spectroscopic techniques.
