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...
متن کاملExploring the Ultrafast Excited-State Intramolecular Proton Transfer (ESIPT) of β-Diketones in the deep-UV
The photodynamics in symmetric and unsymmetric β-diketones are studied with transient absorption in the deep-UV. Excitation leads to ultrafast ESIPT while further relaxation and isomerization processes depend on the molecular symmetry and solvent environment. OCIS codes: (320.7150) Ultrafast spectroscopy; (300.6540) Spectroscopy, ultraviolet; (190.7110) Ultrafast nonlinear optics
متن کاملSpecificity and kinetics of alpha-synuclein binding to model membranes determined with fluorescent excited state intramolecular proton transfer (ESIPT) probe.
Parkinson disease is characterized cytopathologically by the deposition in the midbrain of aggregates composed primarily of the presynaptic neuronal protein α-synuclein (AS). Neurotoxicity is currently attributed to oligomeric microaggregates subjected to oxidative modification and promoting mitochondrial and proteasomal dysfunction. Unphysiological binding to membranes of these and other organ...
متن کاملTuning excited-state-intramolecular-proton-transfer (ESIPT) process and emission by cocrystal formation: a combined experimental and theoretical study.
The formation of two-component molecular cocrystals can lead to the tunable excited state intramolecular proton transfer (ESIPT) process and emission, as first confirmed by both experimental and computational studies.
متن کاملSolvent-dependent excited state intramolecular proton transfer (ESIPT) pathways from phenol to carbon in 2,5-dihydroxyphenyl arenes.
The ESIPT of three 2,5-dihydroxyphenyl-substituted arenes 9-11 was studied in various solvent systems, to investigate the direction of the proton transfer from the phenol to the respective carbons of naphthyl, phenanthrenyl and anthryl aromatic rings. In neat CH3CN, 9-11 undergo direct ESIPT from the phenolic OH to the ipso-position of the corresponding aromatic carbon acceptors, via an intramo...
