Zwischen molekularen und polymeren „Metallen”︁: elektrisch leitfähige, strukturell fixierte Aggregate von Metallomakrocyclen

Abstract: Planung, Synthese, Charakterisierung und Theorie neuer molekularer und makromolekularer Substanzen mit ,,metallischen" elektrischen Eigenschaften ist ein aktuelles Forschungsgebiet im Grenzland zwischen Chemie, Physik und Materialwissenschaften. Ein wichtiges, langfristiges Ziel in diesem Feld der ,,maBgeschneiderten Materialien" ist es, iiber molekulare Aggregate zu entwickeln, die dank ,,eingebauter" Wechselwirkungen zwischen den molekularen Bausteinen bestimmte kollektive Eigenschaften aufweisen.

“…An additional increase is observed in the case of partial oxidation which is discussed in terms of partially filled energy levels with electron transport by means of fluctuation-induced tunnelling. [171] High intrinsic electrical conductivities were also measured for polymeric cofacial stacked phthalocyanines with covalent/coordinative bonds (15) and coordinative/coordinative bonds (16) in the main chain (Table 1). Because the polymers are insoluble in organic solvents no films can be cast.…”

“…As a continuation of our studies on the synthesis and characterization of iodine-doped metallophthalocyanines, we have obtained several of these compounds (Kubiak & Janczak, 1997;Kubiak & Razik, 1998;Janczak et al, 1999Janczak & Kubiak, 1999a,b,c). The I atoms in most iodine-doped metallophthalocyanines form linear chains of symmetrical If ions, which are usually disordered in the crystal (Marks, 1980;Ibers et al, 1982;Janczak et al, 1999a,b;Janczak & Kubiak, 1999a,b). The I atoms can also be bonded directly to the central metal ion, yielding mono-or diiodometallophthalocyanines (Ejsmont & Kubiak, 1997;Janczak & Kubiak, 1999c;Schweiger et al, 1998).…”

“…Quasione-dimensional stacks of strongly interacting mainly planar macrocycles with weak interactions between adjacent stacks are formed, leading to the unusual chargetransport properties (Marks, 1990). On the other hand, oxidized metallophthalocyanines like LiPcI with the same architectural design but with a half-filled valence band may be of considerable interest as MottHubbard isolators.…”
