Electrically bistable memory devices based on poly(triphenylamine)-PCBM hybrids.

Due to the strong interaction between PCBM and triphenylamine, PCBM could be well distributed into poly-4-methoxytriphenylamine (P-TPA). The resulting hybrid films exhibited DRAM behavior at low PCBM concentrations, while they revealed WORM property at higher, 5 wt% and even up to 10 wt%, PCBM concentrations.
