Summary on Grant Application Form |
|
I wish to follow up studies on the polypyridine family of luminescent conjugated polymers work started very successfully with a two year ROPA award. New rigid-rod and semi-flexible polymers will be made to study the effect chain rigidity has on photophysical properties. Regioregular polymers can now be synthesised allowing the study of the effect HH an HT coupling has on the properties of these polymers. This route also allows the synthesis of polymers of high purity. It has been found that rigid polymers spontaneously orient to form highly anisotropic thin films. This will allow the study of inter chain effects and electronic properties in great detail. the effect of such ordering on waveguiding in thin films will be studied with a view to enhancing the lasing properties of such structures. The possibility of lyotropic liquid crystalline phases will be investigated in solutions of rigid rod polymers. Analogues to electrical switching of liquid crystals will be used to order such phases.
