Summary on Grant Application Form
This proposal relates to EPSRC support in the Chemistry Programme, COST-:-European-Chemistry-Collaboration. The investigations constitute the UK component of an international programme seeking a fundamental advance in the application of the theory of the contributions of electric and magnetic dipoles to NLO effects and photorefractivity, practical advances in measurement techniques to allow easy screening of charged compounds for appropriate optical properties, and the synthesis of novel organometallic structures which have been specifically designed to provide the three-dimensional distribution of dipole units required for successful testing of these ideas. First bimetallic rod-like dipole structures will be synthesised to establish the chemistry of the end-groups. The next stage applies metallation chemistry of BINOL ethers to produce chiral structures that combine an organometallic acceptor end-group, with a conventional organic donor group. Extension of this series using related methods with MOM-protected derivatives, followed by deprotection (MOM) and conversion into a di-triflate will prepare for palladium-catalysed introduction of vinylferrocene (Heck coupling). The products will combine two bimetallic units with a chiral binaphthyl central structure. Beta values will be measured. The products will be evaluated in a novel variation of the HRS method to explore the magnetic contribution to NLO effects. Density functional theory (DFT) will guide the design of chromophores to allow the project to identify and synthesise novel classes of structures containing more than one dipole, within architectures with high molecular anisotropies and with optical adsorption properties that are suitable for the proposed photophysics evaluation.
