Abstract

Six redox-active cyclophane/crown hybrid molecules (crownophanes) were prepared via cyclization reactions involving N, N′-dimethyl-p-phenylenediamine and tosylated oligoethylene glycols of varying length. These new host molecules differ from other phenylenediamine-containing crown ethers in that the electron-rich π face is designed to be part of the ligating group. Their electrochemical properties were determined by cyclic ...
