Three soluble D-A type polycarbazole derivatives with different electron acceptors in the side chain, including poly[(9-(2-hexyldecyl)-9H-carbazole)-(9-(4-nitrophenyl)-9H-carbazole)] (PCz-NO2), poly[(9-(2-hexyldecyl)-9H-carbazole)-(4-(9H-carbazole-9-yl)benzaldehyde)] (PCz-CHO), and poly[(9-(2-hexyldecyl)-9H-carbazole)-(4-(9H-carbazole-9-yl)benzonitrile)] (PCz-CN), were synthesized through the Suzuki coupling reaction. These polymers-based electronic devices with a configuration of Al (200 nm)/polymer (90 nm)/Indium-Tin Oxide (ITO) had representative bistable elec. switching behavior and non-volatile write-once read-many-times (WORM) memory performance. When the optical bandgap of conjugated polymer was increased (2.26 Ev (PCz-NO2)→2.79 eV(PCz-CHO)→3.20 eV(PCz-CN)), the threshold voltage of the corresponding electronic device gradually increased (-1.70 V→-1.81 V→-1.89 V), whereas the ON/OFF current ratio was changed from 6.63 × 104 for PCz-NO2 to 4.08 × 104 for PCz-CHO and to 5. 68 × 103 for PCz-CN. Among these three derivatives, PCz-CN exhibited the biggest turn-on voltage and the lowest ON/OFF current ratio.
