title: Photoinduced energy transfer processes in hybrid organic-inorganic multichromophoric arrays arranged on a truxene-based platform.
abstract: The synthesis, photophysical characterization and energy-transfer features of a series of hybrid truxene derivatives peripherally decorated with inorganic Os-containing polypyridine units and organic Bodipy dyes are reported. The photoactive terminal units are coupled to the central truxene scaffold by rigid ethynyl linkers in a star-shaped arrangement. The absorption range widely covers the UV-Vis spectrum and the Os (3)MLCT or the Bodipy triplet act as final collectors of the absorbed energy.
