Strategic emission color tuning of highly fluorescent imidazole-based excited-state intramolecular proton transfer molecules.
Highly fluorescent molecules harnessing the excited state intramolecular proton transfer (ESIPT) process are promising for a new generation of displays and light sources because they can offer very unique and novel optoelectronic properties which are different from those of conventional fluorescent dyes. To realize innovative ESIPT devices comprising full emission colors over the whole visible ...
متن کاملHydrogen Bonds in Excited State Proton Transfer.
Hydrogen bonding interactions between biological chromophores and their surrounding protein and solvent environment significantly affect the photochemical pathways of the chromophore and its biological function. A common first step in the dynamics of these systems is excited state proton transfer between the noncovalently bound molecules, which stabilizes the system against dissociation and pri...
متن کاملAccelerating slow excited state proton transfer.
Visible light excitation of the ligand-bridged assembly [(bpy)(2)Ru(a)(II)(L)Ru(b)(II)(bpy)(OH(2))(4+)] (bpy is 2,2'-bipyridine; L is the bridging ligand, 4-phen-tpy) results in emission from the lowest energy, bridge-based metal-to-ligand charge transfer excited state (L(-•))Ru(b)(III)-OH(2) with an excited-state lifetime of 13 ± 1 ns. Near-diffusion-controlled quenching of the emission occurs...
متن کاملElementary steps in excited-state proton transfer.
The absorption of a photon by a hydroxy-aromatic photoacid triggers a cascade of events contributing to the overall phenomenon of intermolecular excited-state proton transfer. The fundamental steps involved were studied over the last 20 years using a combination of theoretical and experimental techniques. They are surveyed in this sequel in sequential order, from fast to slow. The excitation tr...
متن کاملExcited-State Intramolecular Proton Transfer and Rotamerism of 2-(2′-hydroxyvinyl)benzimidazole and 2-(2′-hydroxyphenyl)imidazole
The intramolecular proton transfer of 2-(2′-hydroxyvinyl)benzimidazole (HVBI) and 2-(2′-hydroxyphenyl)imidazole (HPI) in the ground state and in the 1ππ*, 1nπ*, and 3ππ* excited states has been studied at the HF/CIS/D95** level of theory. Their rotamerism reaction in the ground and 1ππ* excited states has been also analyzed. These systems are two different fragments of 2-(2′-hydroxyphenyl)benzi...
