Formation and luminescence of 1D helical polymeric excimer from Pt-MeO-salen precursor

With the amorphous Pt-MeO-salen solid (MeO-salen = N,N′-bis(3-methoxy-salicylidene)-ethylene-1,2-diamine) as the precursor, a new 1D polymeric complex [K2(Pt-MeO-salen)2Ni(CN)4]n · 0.5nEt2O (1) has been characterized. The luminescent property of the complex shows that the 1D helical stacking of well-defined Pt-MeO-salen monomers has modulated the energy order of the excited state in solid state at different temperatures.
