Photochromism of dihydroazulene-based polymeric thin films / Torres-Pierna, Héctor (Institut Català de Nanociència i Nanotecnologia) ; Roscini, Claudio (Institut Català de Nanociència i Nanotecnologia) ; Vlasceanu, Alexandru (University of Copenhagen. Department of Chemistry) ; Broman, Soren L. (University of Copenhagen. Department of Chemistry) ; Jevric, Martyn (University of Copenhagen. Department of Chemistry) ; Cacciarini, Martina (University of Firenze. Department of Chemistry) ; Nielsen, Mogens Brøndsted (University of Firenze. Department of Chemistry)
We report on the preparation of polymeric thin films doped with six dihydroazulene derivatives whose photochromic properties were previously screened in organic solution studies. Spectroscopic investigations into the photochromic behavior of the polymeric matrices have given important insights on the stability and the photophysical properties of the photoswitches impregnated into polymers.

Fast responsive photochromic materials through nanoemulsion entrapment / Torres Pierna, Héctor ; Roscini, Claudio, dir. ; Hernando Campos, Jordi, dir. ; Universitat Autònoma de Barcelona. Departament de Química
En aquesta tesis doctoral, s'ha desenvolupat un material fotocròmic òpticament transparent amb resposta cinètica ràpida i similar a la dissolució líquida, i hi ha descrita la metodologia per produir aquest material. [...]
En esta tesis doctoral, se ha desarrollado un material fotocrómico ópticamente transparente con respuesta cinética rápida y similar a la disolución líquida, y hay descrita la metodología para producir este material. [...]
Along this thesis, an optically transparent photochromic material with fast and liquid-like kinetic response has been developed, and the methodology to produce said material is described herein. This technology is based on the nanoemulsion entrapment (NEE) technique, in which an nanoemulsion is first formed and stabilized by a film-forming polymer, and then the solvent of the continuous phase is removed, to generate a film containing the emulsion droplets entrapped in it.
