Research Abstract |
It was found in this study that trinuclear Pd complexes of a macrocyclic N6-type ligand simultaneously form four kinds of conformational and stereo isomers in solution and that self-assembly of these isomers results in crystalline nanochannel structure of ca. 2 nm diameter. In the channel, five enantio-paired pockets and various types of hydrogen bonding sites are arranged. In the guest adsorption experiments, a single-crystal was soaked in a guest solution for a given time, and then the position and adsorption patterns of the guest was determined by single-crystal X-ray structural analysis. This method has revealed the adsorption positions of many types of aromatic compounds, metal catalysts, and bio-related compounds, which allowed adsorption mapping. Moreover, simultaneous site-selective adsorption of different multiple guests has been achieved and further developed to multicomponent intermolecular reactions in the channel.
