Self-assembly of a bisporphyrin supramolecular cage induced by molecular recognition between complementary hydrogen bonding sites
Abstract
Addition of an alkyl substituted triaminopyrimidine, TAP, to a solution of porphyrin 2 bearing two rigidly attached complementary hydrogen bonding moieties of the uracil type, leads to the self-assembly of a bisporphyrin supramolecular cage structure 1 from the syn rotamer and probably a zig-zag strand from the anti rotamer.
