Autor: | Santa María, Dolores; Claramunt, Rosa M.; Bobosik, V.; Torralba, M. Carmen; Torres, M. R.; Alkorta, Ibon CSIC ORCID ; Elguero, José CSIC ORCID | Fecha de publicación: | 2013 | Editor: | Pergamon Press | Citación: | Tetrahedron 69: 3027- 3038 (2013) | Resumen: | A total number of nineteen 2-arylbenzotriazoles related to the UV absorber Tinuvin P have been studied. Moreover, besides those bearing a 2′-hydroxy substituent, known to experience ESIPT (Excited-State Intramolecular Proton Transfer), we have also prepared three compounds having another ortho-hydroxy group at position 6′. The X-ray molecular structures of five key representatives have been determined and some important features related to their behavior discussed on the basis of solution and solid-state NMR, as well as B3LYP/6-311++G(d,p) computational results. © 2013 Elsevier Ltd.
