Abstract
4,5,4′,5′‐Tetracyano‐2,2′‐bi‐1,3‐dithiolylidene (tetracyanotetrathiafulvalene) (1) was found to react with metal acetylacetonates (2a–m) to give dark, insoluble, and infusible polymers 3a–m 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.
