Abstract:

Phase 1 of this contract involved the synthesis of several representative compounds containing organic chromophores which are capable of donating and accepting a single electron after two-photo excitation. The selection of suitable chromophores was based on a set preset criteria which is listed in the contract proposal. The suitability of these chromophores for the stated application was determined first by studying their spectroscopic and electron transfer properties as separate molecules in solution i.e. intermolecular. Once the intermolecular behavior of these chromophores was evaluated, synthesis of molecules incorporating both the donating and accepting chromophores was carried out. This report describes the following work 1 spectroscopic evaluation of the two-photon-induced intermolecular electron donoracceptor abilities of the chosen chromophores 2 synthesis of molecules incorporating both the electron donating and accepting chromophores 3 preliminary spectroscopic investigation in solution of the synthesized molecules.
