通过铃木偶联法控制反应条件，合成了一系列新型、功能对称和非对称的双噻吩光致变色低聚物。测量并讨论了它们在THF和聚甲基丙烯酸甲酯（PMMA）薄膜中的光学量子产率、光致变色量子产率、双光子和电化学性能。通过紫外和可见光的交替照射，可以可逆地调节荧光发射。这些bte可以用作纳米线、荧光开关和电化学开关。
A series of novel, functional symmetric and unsymmetric photochromic thiophene oligomers based on bisthienylethenes (BTEs) were synthesized via control of the reaction condition with a Suzuki coupling method. Their optical, photochromic quantum yields, two-photon and electrochemical properties in THF as well as in poly(methylmethacrylate) (PMMA) films were measured and discussed. The fluorescence emission can be tuned reversibly by alternating irradiation with UV and visible light. These BTEs could be used as nanowires, fluorescent switch and electrochemical switch.
