All-organic coaxial nanocables with interfacial charge-transfer layers: electrical conductivity and light-emitting-transistor behavior

All-organic coaxial nanocables with high electrical conductivity and luminescence properties were fabricated by controlled solution blending of poly(3-hexylthiophene) (P3HT) and 1-cyano-trans-1,2-bis-(3′,5′-bis-trifluoromethyl-biphenyl)ethylene (CN-TFMBE). The coaxial nanocables with interfacial charge-transfer doping layers showed a very high electrical conductivity, a chemical-gating feature of the threshold voltage, and efficient light emission.
