Host–Guest Encapsulation to Promote the Formation of a Multicomponent Trigonal-Prismatic Metallacage

An inclusion complex of a trigonal-prismatic metallacage with two coronene guests was constructed by multicomponent coordination-driven self-assembly from a 90° platinum­(II) acceptor [cis-Pt­(PEt3)2(OTf)2], disodium terephthalate, and 2,4,6-tri­(4-pyridyl)-1,3,5-triazine in the presence of excess c...

Description
Summary:An inclusion complex of a trigonal-prismatic metallacage with two coronene guests was constructed by multicomponent coordination-driven self-assembly from a 90° platinum­(II) acceptor [cis-Pt­(PEt3)2(OTf)2], disodium terephthalate, and 2,4,6-tri­(4-pyridyl)-1,3,5-triazine in the presence of excess coronene. This platinum­(II)-based trigonal prism was found to be a highly matched host to simultaneously encapsulate two coronene molecules. The encapsulation of coronene can effectively promote the formation of a pure single-prismatic metallacage and can stabilize the self-assembled structure via strong π–π-stacking interactions between coronene and the metallacage.
