Skewered Cyano-Bridged Cobalt Naphthalocyanine Polymer: An Electron Transport Engineering

Abstract

Naphthalocyanines (Nc) are ideal molecular conductors due to their flat and fully-conjugated structures. Attachment of a central metal (Co) and dicyano (CN) axial ligands to Nc produced CN-bridged cobalt naphthalocyanine, a skewered-type polymer complex. The polymeric species enabled intra-chain electron transport through the CN bridge by which, coupled with the interchain p-p overlaps, produced a multi-dimensional electronic system. This molecular design has decreased the electrical resistivity by 5 orders relative to the monomeric Co(Nc) with di-axial CN complex.
