Towards the generation of photoactive nanomaterials: a supramolecular approach

Objective of these four first chapters is to have a complete understanding of the supramolecular organisation of several complementary modules able to form 2-D networks first in solution using optical spectroscopy measurements as function of solvent polarity , concentration and temperature, and then on solid surface using microscopy techniques such as STM, AFM and TEM. The last chapter presents another type of supramolecular material for application in solar cells technology involving fullerenes and OPV systems. We describes the photoinduced energy and electron process using transient absorption experiments. All these systems provide an exceptional example for the potential of the supramolecular approach as an alternative to the restricted lithographic method for the fabrication of adressable molecular devices.
