This invention relates to an energy-transfer type light-emitting polymers based on poly(p-phenylene vinylene)s containing two or more kinds of luminous elements which are completely isolated by an ether group in the backbone, having the following structural formula. The conjugated length of each kind of luminous element can be adjusted and different luminous elements can be effectively isolated by an ether bond as a linking element and an isolating element. Meanwhile, different luminous elements can independently emit, which provides the precondition of energy transfer between different luminous elements in relation to molecular structure and therefore the fluorescence quantum efficiency can be improved.

本发明涉及一种基于聚(对苯基乙烯基)的能量传递型发光聚合物,该聚合物含有两种或两种以上的发光元素,这些发光元素在骨架中被一个醚基完全隔离,其结构式如下。每种发光元素的共轭长度可以调整,不同的发光元素可以通过作为连接元素和隔离元素的醚键有效隔离。同时,不同的发光元素可以独立发光,这就为不同发光元素之间的能量传递提供了与分子结构相关的前提条件,从而提高了荧光量子效率。
