Abstract

Bridged quasi-one-dimensional macrocyclic transition metal complexes [MacM(L)] using phthalocyanine (Pc) tetrabenzoporphyrine (TBP), 1,2- and 2,3-naphthalocyanines (1,2-Nc; 2,3-Nc) as macrocycles (Mac) with M = e.g., Fe, Ru, Co and L = e.g., pyrazine (pyz), 1,4-diisocyanobenzene (dib), tetrazine (tz) exhibit interesting electrical properties. Regardless of the size of the bridging ligand after either chemical or electrochemical doping stable semiconducting compounds [MacM(L)X] (X = e.g., I BF, ClO...) are formed. For the first time the complete characterization of soluble oligomers [MacM(L)] (Mac = t-BuPc, M = Ru, L = dib, medib) by H-NMR spectroscopy is reported. Some of these shish kebab complexes, e.g., [PcM(tz)], (M = Fe, Ru) or [MacMCN[; (Mac = Pc, TBP; M = Co,Fe) exhibit good semiconducting properties without additional external doping. Whether or not these compounds are intrinsic semiconductors will be discussed. The synthesis of oligomeric bridged mixed valence compounds [PcM(III)LPcM(II)L] (M = e.g., Fe) is another target of our work. We report here on first results of these oligomers.
