A polymer composed of ruthenium carbonyl and of the formula [Ru6C(CO)(15)Ph2PCCPPh2](n) has been synthesized. It is found to behave as a negative electron-beam resist with a sensitivity of 400 C/m(2). Upon exposure to the electron beam, the electrical conductivity of the patterned films is found to vary over seven orders of magnitude according to a power-law dependence on dose. Temperature dependence of the conductivity is studied, and the conduction is attributed to variable-range hopping between ruthenium superclusters in two dimensions.
