Caging ultrafast proton transfer and twisting motion of 1-hydroxy-2-acetonaphthone: 711-79-5 is the cas registry number of certain chemical which is used as reagents here. Caging ultrafast proton transfer and twisting motion of 1-hydroxy-2-acetonaphthone. Organero, J. A.; Tormo, L.; Douhal, A. (Facultad de Ciencias del Medio Ambiente, Departamento de Quimica Fisica, Seccion de Quimicas, Universidad de Castilla-La Mancha, Toledo 45071, Spain). Chemical Physics Letters, 363(3,4), 409-414 (English) 2002 Elsevier Science B.V. CODEN: CHPLBC. ISSN: 0009-2614. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) We report on emission studies of 1-hydroxy-2-acetonaphthone (HAN) in soln. nanocavities. In neutral water solns., intramol. proton transfer in the enol (E*) structure of HAN and a subsequent internal rotation in the formed keto-type tautomer (K*) occur in few tens of ps, to produce a ns-living rotamers (KR*). When caging HAN in cyclodextrins, the dynamics of twisting is greatly affected.In this experiment, several chemicals are used like 711-79-5 and 17465-86-0 Depending on the size of the cage, the isomerization channel leading to KR* can be closed, and emission occurs from K*. In a larger caging cavity, the fast component of the anisotropy decay becomes shorter while the slow one becomes longer. ..

Temperature and solvent effects on the photodynamics of 1'-hydroxy-2'-acetonaphthone: Temperature and solvent effects on the photodynamics of 1'-hydroxy-2'-acetonaphthone. Organero, J. A.; Douhal, A. (Facultad de Ciencias del Medio Ambiente, Departamento de Quimica Fisica, Seccion de Quimicas, Universidad de Castilla-La Mancha, Toledo 45071, Spain). Chemical Physics Letters, 381(5,6), 759-765 (English) 2003 Elsevier Science B.V. CODEN: CHPLBC. ISSN: 0009-2614. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 74 We present studies of temp. viscosity and polarity effects on the photodynamics of 1'-hydroxy-2'-acetonaphthone. We obsd. a striking temp. effect on the non-radiative decays and which explains the low emission quantum yield of the formed keto-type phototautomers. The thermal activation energy is lower for the keto structure (0.96 kcal/mol) than for the keto rotamer one (3.4 kcal/mol). For the alcs. family of solvents, the keto-type tautomer is more sensitive to solvent response than the keto rotamer. 477591-47-2 and 711-79-5 are just another two chemicals used in this study. However for non-hydroxylic media the low influence of solvent polarity is similar for both keto type structures. .
