Abstract
Luminescence and photoinduced energy- and electron transfer are phenomena of great importance for a number of applications in many areas, e.g. sensing and optoelectronics [1]. In particular, we investigate such fundamental processes in photoactive molecules, metal complexes, supramolecular arrays and nanomaterials which are targeted at (i) efficient lighting devices (Light Emitting Electrochemical Cells, LECs) [2] and (ii) light harvesting and charge separation in model solar energy conversion systems [3,4]. In this context, some recent work will be presented on luminescent Ir(III) and Cu(I) complexes [5,6], red-emitting hybrid materials made of Eu(III)-based luminophores and carbon nanonotubes [7], and photoinduced processes in multichromophoric systems containing fullerenes and other electron acceptors [4]. These results will be framed in the more general context of the ongoing transition to a sun-powered world [8]. [1]Praveen, V. K.; Ranjith, C.; Bandini, E.; Ajayaghosh, A.; Armaroli, N. Chem. Soc.
