合成了具有“天线－敏化中心”结构的新型光敏剂〔Ｒｕ（ｂｐｙ）２（ＣＮ）２〕２Ｒｕ（ｂｐｙ（ＣＯＯ）２）２２－这种超分子体系含有两种发色团，因而相对于单分子体系，它的吸收范围较宽而且这种分子内部可进行能量传输，所以能更为有效地利用太阳光能另外，这种光敏剂较长的发射寿命３６０ｎｓ（乙醇溶液，除氧，２９８Ｋ）有利于向半导体导带注入电子以实现电荷分离 A new photosensitizer [Ru (bpy) 2 (CN) 2] 2Ru (bpy (COO) 2) 22- with the structure of “antenna-sensitization center” was synthesized. This supramolecular system contains two chromophores, Relative to the monomolecular system, its absorption range is wide  and this molecule can be energy transfer within, it can be more effective use of solar energy  In addition, the photosensitizer longer emission life of 360ns (ethanol solution, Oxygen, 298K) facilitates the injection of electrons into the semiconductor conduction band for charge separation
