  1. Synthesis of light-emitting liquid crystal molecules G. Tu, W.T.S. Huck Melville Laboratory for Polymer Synthesis, Department of Chemistry, University of Cambridge. Introduction: Nano-confinement technique and applications • Nano-confinement polymer devices1: • 1) Polarized electroluminescence with a polarization ratio of 11; • 2) Ambipolar PFET mobilities were improved 10-15 and 5-7 times for hole and electron transport, respectively, because of the alignment of the F8BT in devices; • Advantages of small molecules for nano-confinement devices: • Faster movement than polymer at the same temperature; • Fixed and homogeneous molecular weight and molecular size; Synthesis of red light-emitting molecules for nano-confinement laser Rigid Core and High Molecular Weight Rigid Block Synthetic route: • Conclusions: • Di- and tri- block conjugated LC molecules were synthesized with molecular weight of 2028 and 3143, respectively; • High quality spin-coated films can be obtained from these two intramolecular charge red light-emitting molecules; Further reading:Nano Letters, 7, 987-992 ; www-g.eng.cam.ac.uk/cosmos COSMOS is a Basic Technology Research Grant funded by the EPSRC, EP/D04894X
