-benzoxazole: two photostabilizers that undergo excited-state proton transfer
Electroabsorption is used to determine the difference dipole moment, NDmN , and the difference polarizability, Da , of Ž . HBT and HBO, two molecules that undergo excited-state intramolecular proton transfer ESIPT . These measurements are Ž ). Ž . compared to ab initio 6-31G and semi-empirical INDO1rs calculations. Good agreement is obtained between ab initio and experimental NDmN values. Howev...
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 کاملPanchromatic luminescence from julolidine dyes exhibiting excited state intramolecular proton transfer.
The preparation and the photophysical behaviour of novel julolidine derivatives designed for displaying excited state intramolecular proton transfer (ESIPT) are reported. These dyes exhibit panchromatic photoluminescence covering the whole visible spectral range, both in organic solvents and in the solid state.
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...
