Hybrid structures consisting of semiconducting polymers and strongly luminescent semiconductor nanocrystals offer favourable perspectives in display technology through a combination of low cost wet-chemical processability with a highly saturated emission colour, which is of importance to the development of full colour large area flat panel displays. Further fields of possible applications are hybrid organic-inorganic light-emitting diodes and solar cells. This project addresses the development of smart combinations of semiconducting polymers that are directly attached to semiconductor nanocrystals through a proper choice of functional groups of the polymers, paving the way to novel composite functional materials. Investigation and optimisation of energy transfer, charge generation and transport in these materials will be carried out, being of beneficial impact towards improved efficiency of hybrid polymer/nanocrystal devices.

由半导体聚合物和强发光半导体纳米晶体组成的混合结构通过低成本的湿化学加工性与高度饱和的发射颜色的组合在显示技术中提供有利的前景，这对于全色大面积平板显示器的发展是重要的。可能应用的其它领域是混合有机-无机发光二极管和太阳能电池。该项目致力于通过适当选择聚合物的官能团直接连接到半导体纳米晶体的半导体聚合物的智能组合的开发，为新型复合功能材料铺平道路。研究和优化这些材料中的能量转移、电荷产生和传输，将对提高混合聚合物/聚合物器件的效率产生有益的影响。
