Abstract

A series of fluorene and bipyridine (bpy) copolymers were synthesized, and their optical properties were investigated in the presence of zinc(II). By adjusting the bpy content in the polymer backbone, the emitting color of the polymer solution could be tuned from initial blue to green to white and violet when it interacted with zinc(II) ions. The counteranions of zinc(II) ions were also found to influence the optical properties of copolymers greatly.

摘要

合成了一系列芴和联吡啶（bpy）共聚物，并研究了它们在锌（II）存在下的光学性质。通过调节聚合物主链中的bpy含量，当聚合物溶液与锌（II）离子相互作用时，其发射颜色可从初始的蓝色调至绿色、白色和紫色。还发现锌（II）离子的抗衡阴离子对共聚物的光学性质有很大影响。
