Abstract

A complete assignment of 13C NMR resonance peaks in the spectrum of heteroleptic triple-decker (porphyrinato)(phthalocyaninato) lanthanum of type [Br4TPP]La[(15C5)4Pc]La[Br4TPP] ( Br4TPP = 5,10,15,20-tetrakis-(4-bromophenyl)-porphyrinato-ligand, (15C5)4Pc = tetrakis-(15-crown-5)-phthalocyaninato-ligand) is performed. Application of set of gradient-enhanced homonuclear 1H-1H-correlation techniques (COSY and NOESY) allowed the unambiguous interpretation of proton spectrum of the complex. Application of INEPT polarization transfer technique allowed to separate quaternary carbon resonances from proton-bound carbon ones. Gradient-enhanced proton-detected HMQC and HMBC techniques allowed to correlate all the resonances in 13C-spectrum.
