Summary on Grant Application Form |
|
Functional molecules will be constructed which contain three components. The first of these will be a porphyrin photoelectron donor, the second a redox-active metal based electron acceptor and the third a modifier functionality. The redox active acceptor centre may be {Mo(NO)} or {Mo(=O)} either of which should be reduced by the porphyrin excited singlet state. In addition {W(NO)} will be used as a non-reducible centre for comparison. The modifier will consist either of a pair of the above metal centres but which are not reducible centre for the photoelectron donor, or a cyclic polyether capable of stabilising the reduce form of the acceptor group through binding a cationin guest. The electron transfer and spectroscopic properties of the new compounds will be measured to establish the redox potentials of the various components and the possible charge separation pathways available within the molecule. Excitation of the prophyrin will, in suitable cases, result in electron transfer from the porphyrin to the metal based acceptor and the effect on charge separated state lifetimes of two types of modifier component of this diad system will then be determined.
