The synthesis of newly designed photochromic dithienylethene-containing ethynylthiophene and ethynylthieno[3,2-b]thiophene has been described, and their incorporation as versatile ligands into the platinum(II) phosphine system was demonstrated. All platinum(II) complexes have been successfully characterized by (1)H and (31)P NMR spectroscopies, positive fast atom bombardment (FAB) mass spectrometry, as well as elemental analysis. One of the complexes has been characterized by X-ray crystallography. Their photophysical, photochromic, and electrochemical properties have been studied. Upon photoexcitation, all the photochromic diarylethene-containing alkynes and platinum(II) complexes exhibited reversible photochromism. The thermal bleaching kinetic of complex 6 was studied in toluene at 298 and 313 K. Complexes 1, 3, and 4, which contained the labile chloro- ligand, represent a new class of versatile building blocks for photoswitchable functional materials.
新设计的含二噻吩乙烯的炔基噻吩和炔基噻吩[3,2-b]噻吩的合成已经描述，并且它们作为多功能配体被并入铂（II）膦体系中。所有的铂（II）配合物都已经通过（1）H 和（31）P NMR 光谱、正快速原子轰击（FAB）质谱以及元素分析成功地进行了表征。其中一个配合物已经通过 X 射线晶体学进行了表征。它们的光物理、光致变色和电化学性质已经进行了研究。在光激发下，所有的含二芳基乙烯的光致变色炔烃和铂（II）配合物都表现出了可逆的光致变色性。在 298 和 313 K 的甲苯中研究了配合物 6 的热褪色动力学。配合物 1、3 和 4 含有不稳定的氯配体，代表了一类新的用于光开关功能材料的多功能构建块。
