Abstract
This paper reports on an approach to control molecular stacking interactions in low-dimensional mixed valence materials by locking partially oxidized metallomacrocycles together in a cofacial orientation. Iodine doping of the face-to-face linked oligomers [M(Pc)O]n (M = Si, Ge, Sn; Pc = phthalocyaninato) produces electrically conductive polymers {[M(Pc)O]Ixn with a wide range of x stoichiometries. Resonance Raman spectroscopy indicates that the iodine has oxidized the polymer chain. Polymer structure has been studied by X-ray powder diffraction, and it is possible to estimate interplanar spacings. Halogen doping of the [M(Pc)O]n materials is accompanied by electrical conductivity increases as large 107 (ohm cm)-1; the general trend is σSi {greater-than or approximate} σGe > σSn. Variable temperature conductivity and magnetic susceptibility data are reported.
