N2 - A novel one-pot procedure starting from the corresponding M(acac) 3·nH2O, metal-free phthalocyanine H 2Pc′, and naphthalonitrile in the presence of DBU in n-octanol has been developed to prepare heteroleptic (naphthalocyaninato)- (phthalocyaninato) rare earth double-decker complexes. A series of six sandwich compounds with different naphthalocyaninato ligands, phthalocyaninato ligands, and central rare earth metals, namely, Sm[Nc(tBu)4](Pc) [Nc(tBu) 4 = 3(4),12(13),21(22),30(31)-tetra(tert-butyl)naphthalocyaninato; Pc = unsubstituted phthalocyaninato] (1), Sm(Nc)(Pc′) [Pc′ - Pc(OC5H11)4, Pc(OC8H 17)8; Nc = 2,3-naphthalocyaninato; Pc(OC5H 11)4 = 2(3),9(10),16(17),-24(25)-tetrakis(3-pentyloxy) phthalocyaninato; Pc(OC8H17)8 = 2,3,9,10,16,17,24,25-octakis(octyloxy)phthalocyaninato] (2, 3), and M(Nc)[Pc(α-OC5H11)4] [M = Sm, Eu, Y; Pc(α-OC5H11)4 = 1,8,15,22-tetrakis(3- pentyloxy)phthalocyaninato] (4-6), have been isolated in good yields from this one-pot procedure demonstrating the generality of this synthetic pathway. In addition to spectroscopic analyses, the electrochemistry of these novel compounds has also been studied by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods.
