通过Suzuki交叉偶联反应成功地合成了一种多功能的二（2，5-二甲基-3-噻吩基）-1，10-菲咯啉光致变色配体。二噻吩基邻菲咯啉光致变色反应的激发波长可从紫外区的λ ≤ 340 nm扩展到λ ≤ 340 nm。480 nm处的可见光区，对应于MLCT激发，通过纳入到三（I）三羰基系统。还证明了通过光致变色反应的发射状态的可逆切换。
A versatile bis(2,5-dimethyl-3-thienyl)-1,10-phenanthroline photochromic ligand has been successfully synthesized via a Suzuki cross-coupling reaction. The excitation wavelength for photochromic reaction of the dithienylphenanthroline could be extended from lambda </= 340 nm in the UV region to ca. 480 nm in the visible region, corresponding to the MLCT excitation, through the incorporation into the rhenium(I) tricarbonyl system. Reversible switching of the emissive state by the photochromic reaction has also been demonstrated.
