中文摘要: 首先感谢国家自然科学基金委的资助。 本项目通过三年来的实施,通过把发蓝、绿、红色光的发色团连接到一个大的分子上,得到单分子白光。首先做到了,把绿光分子接到一个发蓝光的大环上。得到了蓝绿的混合光,这证明了申请书的研究内容和目标是可以实现的。研究路线是可行的。 为确保研究目标的实现,本项目在四条线上开展了合成工作:1,大环状的芳胺类的修饰连接蓝、绿、红磷光基团;2,具有共平面结构的苯基咔唑上修饰连接蓝、绿、红磷光基团;3,四苯基甲烷上修饰连接蓝、绿、红磷光基团;4,四苯基硅烷上修饰连接蓝、绿、红磷光基团。在第1条线上的工作完成了大约80%,在第4条线上的工作完成了大约85%,在其它三条线上的工作完成了大约50%。 虽然,本项目目前已经结题,但该项目还需要坚持做下去,且前景光明。学校的第2期配套基金刚刚下拨,加上其它自筹经费,是完全可以完满完成本项目的。

英文摘要: We thank the support of National Natural Science Foundation! To carry out of the project in the three-year period, we try to connect the blue-emitting, green-emitting and red-emitting fluorescent moieties into a super-big molecule and obtain a white-emitting single molecule. We finally successfully obtained a blue-green mixed color emitting single molecule. This successfully proves that the research goals and routes can be practically achieved experimentally. We did the following experiments: 1), connect the blue-emitting, green-emitting and red-emitting fluorescent moieties into a super-big cyclic arylamine molecule; 2), connect the blue-emitting, green-emitting and red-emitting fluorescent moieties into a super-big co-planar carbazole molecule; 3), connect the blue-emitting, green-emitting and red-emitting fluorescent moieties into a super-big tert-phenyl methane molecule; 4), connect the blue-emitting, green-emitting and red-emitting fluorescent moieties into a super-big tert-phenyl silane molecule. We finished nearly 70% of 1) , 85% of 4) and 50% of 2) and 3). Although this project is already terminated, we will continue our research under the support of our university's complimentary financial support and fulfill our research goals.
