Synthesis and Spectroscopic Properties of Homoleptic Bis[octakis(octyloxy)phthalocyaninato] Rare Earth (III) Sandwich Complexes

摘要

A series of homoleptic bis[2,3,9,10,16,17,23,24-octakis(octyloxy)phthalocyaninato] rare earth(III) sandwich compelxes {MPc(OC_8H_17)_8]_2 (M =La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Y, Ho, Er, Tm) (1) and (3)-(13), and HCe[Pc(OC_8H_17)_8]_2 (2)} has been prepared by the cyclic tetramerization of 4,5-di(octyloxy)phthalontirle on the template of M(acac)_3·nH_2O in the presence of 1,8-diazabicyclo[5.4.0]undec-76-ene. Their spectroscopic properties were systematically investigated by ultraviolet-visible, near-infrared, infrared, and mass spectroscopy, and the affects of ionic radius on the inter-ring electronic communication are described.
