A novel polymer, toluylene 2, 4-dicarbamidonitrile (TDCN) with carbon-
nitrogen conjugated backbones, has been synthesised in our Polymer Lab
oratory. The C-60-TDCN thin films have been prepared by the ICB-TOFMS
deposition system. The C-60-TDCN thin films are very good crystalline
and possess electric bistability.
