F. Wurthner et A. Sautter, Highly fluorescent and electroactive molecular squares containing perylenebisimide ligands, CHEM COMMUN, (6), 2000, pp. 445-446
Large functional molecular squares have been assembled with ditopic perylen
e bisimide bridging ligands and Pt(II) and Pd(II) phosphine corner units an
d their optical, electrochemical and spectroelectrochemical properties have
been studied.
