Abstract

With the view to exploit novel rare-earth heteroleptic corrole–phthalocyanine triple-decker complexes towards their potential applications in the fields of information storage devices and nonlinear optical materials, three europium triple-decker complexes containing one meso-substituted trans-A2B-corrole and two phthalocyanine macrocycles have been designed and synthesized. The investigated compounds are represented as Eu2[Pc(OC4H9)8]2[Cor(p-R1Ph)2(p-R2Ph)], where Pc = phthalocyanine, Cor = corrole, (p-R1Ph) and (p-R2Ph) are the substituents on the 5,15-meso and 10-meso positions of the corrole macrocycle, respectively, R1 is H, and R2 is a CH3O, F or Cl substituent at the para-position of the meso-phenyl ring. These novel europium triple-decker complexes were characterized by spectroscopic and electrochemical techniques in nonaqueous media. Under excitation at 633 nm, a typical Raman marker band of the phthalocyanine dianions Pc2− is observed at 1505 cm−1, resulting from the coupling of the C[double bond, length as m-dash]C (pyrrole) and C[double bond, length as m-dash]N (aza group) stretchings. The UV-visible spectra and redox potentials of each triple-decker were analyzed as a function of the sum of the Hammett substituent constants for the para-substituents on the meso-phenyl rings of the corrole macrocycle.
