aAdditionally, most of the known examples feature two or more atoms between an NHC nitrogen and a diphenylphosphino group, leading to rather flexible, often hemilabile metallacycles 另外,大多已知的例子以两个或多个原子为特色在NHC氮气和diphenylphosphino小组之间,导致相当灵活,经常hemilabile metallacycles...
Taken together, these components form the well-known Mollow structure in the fluorescence spectrum11. Interestingly, when considered individually, each of these components also contains higher photon-number components, that is, two or more photons at the same time and place. In view of this fact,...
