研究了钌基光敏剂[Ru（tbbpy）（2）（biH（2））]（2+）与分子金属氧化物[beta-Mo_8 O_（26）]（4-）在溶液和固体状态下的分子间相互作用。采用H-1-NMR、UV-Vis、发射光谱、ESI质谱和单晶X-射线衍射等方法研究了超分子间的相互作用。超分子聚集体的形成，观察到在晶格和在溶液中。此外，它表明，在溶液中的聚集可以通过离子对的竞争形成控制。
The intermolecular interactions between a ruthenium-based photosensitizer ([Ru(tbbpy)(2)(biH(2))](2+)) and a molecular metal oxide ([beta-Mo8O26](4-)) are investigated in solution and in the solid state. The supramolecular interactions were studied using H-1-NMR, UV-Vis and emission spectroscopy, ESI mass spectrometry and single-crystal X-ray diffraction. The formation of supramolecular aggregates was observed both in the crystal lattice and in solution. In addition, it is shown that aggregation in solution can be controlled by the competitive formation of ion pairs.
