Unusual conformational preference of an aromatic secondary urea: solvent-dependent open-closed conformational switching of N,N′-bis(porphyrinyl)urea

Abstract

N,N′-Bis(2,3,7,8,12,13,17,18-octaethylporphyrin-5-yl)urea (3) exhibits cistrans conformational switching depending on the solvent properties, and can adopt the cofacial porphyrin dimer structure under certain conditions. The conformational preference can be switched by electrochemical stimulus.
