Abstract

4,5,4′,5′‐Tetracyano‐2,2′‐bi‐1,3‐dithiolylidene (tetracyanotetrathiafulvalene) (1) was found to react with metal acetylacetonates (2am) to give dark, insoluble, and infusible polymers 3am with phthalocyaninelike structure. The electrical conductivity of the polymers was investigated (σ~298K~ < 6·10^−5^ Ω^−1^ cm^−1^), and a linear relationship between the logarithm of the electrical conductivity and the activation energy of the different polymers was found (compensation effect). Measurements of the thermoelectric power proved p‐conduction.

## Abstract 2.5‐Diamino‐3.4‐dicyanthiophen wurde mit Terephthalsäuredichlorid zu einem Polyamid und mit Thiophen‐2.5‐dicarbaldehyd zu einem Polyazomethin umgesetzt. An beide Polymere konnte durch Reaktion mit Phthalodinitril und Kupferacetylacetonat ein phthalocyaninartiges System anelliert werden.
