Abstract

Coaxially polymerized, peripherally substituted derivatives of phthalocyanine (‐[SiPc(C~n~H~2__n__+ 1~)~8~‐O‐]; n = 8, 12) have been synthesized and characterized. They display efficient energy‐migration properties and a dark conductivity at room temperature of 2 × 10^−2^ S · m^−1^, even in the absence of dopants. The temperature dependence of the conductivity for the C~8~ derivative, over the range ‐ 50 to + 200°C, is given, to a good approximation, by σ = 1.5 · exp [‐ E~a~/(k~B~ · T)] S · m^−1^ with an activation energy E~a~ of 0.11 eV (2.5 kcal/mole). This material could be an example of an intrinsic, one‐dimensional conducting polymer.
