Summary on Grant Application Form |
|
The target of this proposal is a high density read/write memory based upon opto-electronic principles, incorporating carefully designed organic molecules that can undergo photo- electrochemical switching. There has recently been exciting progress in this area, both in new systems that show photoisomerism in organised monolayers and of new methods for writing to and reading such memories at submicron resolution using Near Field Optical microscopy. Substantial effort has been devoted in the UK and elsewhere to the use of organised monolayers based on Langmuir-Blodgett films, but this proposal seeks to move away from LB films to systems that can accommodate photoisomerism and electrochemical conversion without associated steric problems, by exploiting the partial ordering found in discotic liquids. As far as we are aware, this has not been proposed before; by allowing the isomeric changes to take place in the relatively free space between the discotic columns, steric problems of accommodating such changes should be alleviated and the memory device made significantly more stable.
