Abstract

Charge-carrier mobilities of various self-assembled platinum complexes were measured by time-resolved microwave conductivity techniques in the temperature range –80 to +100¿°C. Eight compounds were investigated in the present study, including the original Magnus' green salt ([Pt(NH3)4][PtCl4]) and derivatives with the general structure [Pt(NH2R)4][PtCl4], where R denotes an alkyl side chain. In one instance, the chlorines were substituted with bromines. For these complexes, which all consist of a linear backbone of platinum atoms with Pt–Pt distances, d, varying from 3.1 to =¿3.6¿Å, a strong, inverse correlation was found between d and the one-dimensional charge-carrier mobility, Sµ1D. The highest value of Sµ1D at room temperature was observed for R¿=¿(S)-3,7-dimethyloctyl (dmoc) with Sµ1D =¿0.06¿cm2¿V–1¿s–1. Almost all materials exhibited a charge-carrier mobility that was relatively independent of the temperature over the range studied. One exceptional compound (R¿=¿(R)-2-ethylhexyl) showed a pronounced negative temperature dependence of the charge-carrier mobility; upon decreasing the temperature from +100¿°C to –80¿°C the charge-carrier mobility increased by a factor of about ten.
