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
已描述了新设计的含光致变色二噻吩基乙烯的乙炔基噻吩和乙炔基噻吩并[3,2- b ]噻吩的合成,并证明了它们作为通用配体掺入铂(II)膦系统中。所有的铂(II)配合物均已通过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表征。复合物之一已通过X射线晶体学表征。已经研究了它们的光物理,光致变色和电化学性质。光激发后,所有含光致变色二芳基乙炔的炔烃和铂(II)配合物均表现出可逆的光致变色。配合物的热漂白动力学6在甲苯中在298和313配合物K.研究1,3和4,其中载有不稳定的氯配体,代表一类新的多功能积木用于光开关的功能材料。
