Description
Summary:The synthesis of covalent cages consisting of two porphyrins connected by four flexible spacers each incorporating two 1,2,3-triazolyl ligands is reported. Binding of four silver( i ) to the peripheral ligands induces conformational changes in solution and locks the porphyrins in a face-to-face disposition. A flexible covalent cage was synthesized thanks to a DABCO-templated CuAAC reaction. Coordination of Ag( i ) on the peripheral triazoles locks the conformation of the porphyrin cage.
