Abstract
Luminescence and photoinduced energy- and electron transfer are key fundamental processes that are acquiring an increasing importance for a number of applications in many fields. We are particularly concerned with those related to lighting and solar energy conversion [1,2], which entail the use of suitably designed molecules, metal complexes, supramolecular multicomponent arrays and nanomaterials [3-6]. In this context, we will focus in particular on (i) our most recent results on blue-emitting Ir(III) complexes [7] and red-emitting hybrid materials made of Eu(III)-based luminophores grafted outside [8] or encapsulated inside [9] carbon nanonotubes and (iii) on the study of photoinduced processes in multichromophoric systems containing fullerenes [10] and other novel electron acceptors, which require the use of ultrafast spectroscopic techniques.
