英文摘要： As the development of organic light-emitting diodes applied in display technology field, polarized luminescent liquid crystal materials and their devices have attracted much attention. In order to overcome these defects, such as type sole of polarized luminescent materials, low charge carrier mobility and polarization luminous efficiency, in this project, a combination of triphenylene (or 2,4,6-triphenyl-1,3,5-triazine) and naphthylpyridine are used as mesogens and alkyl are regarded as flexible groups while carbazole derivative or triphenylamine derivative are used as donor unit as well as naphtylpyridine-based platinum complexes or 1,3,5-triazine are used as accept unit to design two classes of D-A cyclometalated platinum complexes liquid crystal polarized luminescent materials. The influence of the molecular structure on the luminescence, liquid crystal, charge carrier mobility and polarized properties will be investigated. Additional, the relationship between the rule of molecular building and polarized property will be also explored. At last, the high luminous and high charge carrier mobility cyclometalated platinum complex-based luminescent liquid crystal materials will be obtained, which plays an important role to promote the development of the industry background light source and lay the foundation for t
