Amplifying Different [2]Catenanes in an Aqueous Donor−Acceptor Dynamic Combinatorial Library
摘要:
Two donor-acceptor [2]catenanes have been synthesized and characterized from a single dynamic combinatorial library in water. One of these catenanes is different from earlier related interlocked molecules in that two donor units stack on each other in an unexpected order. Shifting the equilibrium by choosing the right conditions resulted in a significant increase in the yields of the individual catenanes.

moon is in the seventh house: A conformationally switchable donor–acceptor [2]catenane was synthesized from a dynamic combinatorial library in water. The arrangement of the π units in one of the observed conformations features an unprecedented Gemini shape, which is reminiscent of the astrological Gemini sign (see picture). The catenane can be switched between the parallel and nonparallel conformations
