摘要：高度有序、三维结构的树枝状大分子(dendrimers)作为功能有机材料越来越引起人们的兴趣。与传统的小分子和高分子发光材料相比,树枝状化合物在发光材料方面的应用具有无可比拟的优势。树枝状发光材料的发光特性可以方便地由中心核调换不同的荧光染料来实现,另外大量的表面功能团和不同的代数可供选择来得到一些有趣的性质,如载流子传输功能、区域隔离效应、溶解性和天线效应等。该类型的发光材料已被认为是第三类电致发光材料。本文简要介绍近期树枝状分子在有机电致发光材料领域中的研究进展,评述树枝状分子在该研究领域所特有的优势,重点介绍了树枝状化合物的设计及其对应的性质,并进一步展望树枝状分子未来在有机电致发光领域的研究前景。
Well-defined dendrimers, with highly branched and regularly repeating molecular architectures have generated great interesting. They possess considerable advantages over the well-developed conjugated polymers and small molecular light-emitting materials, whose luminescence can be finely tuned by changing the core with a wide range of luminescent chromophores. Furthermore, various functional surface groups and different generations can be selected to generate the interesting properties such as carrier-transporting, site isolation, solubility and antenna effects. Along with the luminescent molecular and polymeric materials, light-emitting dendrimers are becoming the third class of emissive materials for use in OLEDs. This paper reviews the recent developments in dendrimeric electroluminescent materials, and particular attention is paid on the design of dendrimers and relative properties. The further developing tendency of dendrimers in electroluminescence field is also prospected. ＂
