Mechanism of an Exceptional Class of photostabilizers: a seam of conical intersection parallel to excited state intramolecular proton transfer (ESIPT) in o-hydroxyphenyl-(1,3,5)-triazine.

We present a detailed CASSCF study of the mechanism of excited-state intramolecular proton transfer (ESIPT) in the o-hydroxyphenyl triazine class of photostabilizers. The valence-bond analysis of the ground state and the two pipi* excited states permits a simple chemical interpretation of the mechanistic information. Our results show that the barrier to enol-keto tautomerism on the ground-state...

Quantum Dynamics of the Excited-State Intramolecular Proton Transfer in 2-(2¢-Hydroxyphenyl)benzothiazole

The excited-state intramolecular proton-transfer dynamics and photoabsorption associated with the ketoenolic tautomerization reaction in 2-(2¢-hydr oxyphenyl)benzothiazole are simulated according to a numerically exact quantumdynamics propagation method and a full-dimensional excited-state potential energy surface based on an ab initio reaction surface Hamiltonian. The simulations involve the p...

Detection of boronic acids through excited-state intramolecular proton-transfer fluorescence.

Boronic acids are versatile reagents for the chemical synthesis of organic molecules. They and other boron-containing compounds can be detected readily by the interruption of the excited-state intramolecular proton transfer (ESIPT) of 10-hydroxybenzo[h]quinolone. This method is highly sensitive and selective, and useful for monitoring synthetic reactions and detecting boron-containing compounds...

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 ...

Excited state intramolecular proton transfer (ESIPT) in dihydroxyphenyl anthracenes.

The photochemistry of three 9-(dihydroxyphenyl)anthracenes 6-8 was studied in neat CH(3)CN and selected organic solvents, to investigate excited state intramolecular proton transfer (ESIPT) from the phenol to the anthracene moiety. In D(2)O-CH(3)CN mixtures, the observed deuterium exchange of 6-8 is consistent with water-mediated (formal) ESIPT process from the ortho phenolic OH to the 10'-posi...
