dc.description.abstract The alternating current (AC) and direct current (DC) electrical response of a number of n-alkyl methacrylate polymers with a charge transporting pendant carbazole ring were studied. The electrical properties of the polymers were studied as a function of the n-alkyl length with n ranging from 2 to 11. The DC current (I)-voltage (V) response of the polymers was characterized by an erratic and bistable response, while their AC I-V response was a pinched hysteresis loop when measured between 1-100 Hz. For polymers with n < 9, their pinched hysteresis loop was characterized by "jump transitions" indicative of bistability, while polymers with n ≥ 9 had a pinched hysteresis loop that was smooth in appearance. Dielectric spectroscopy on the polymers indicated that as the n-alkyl length is increased, the rotation flexibility of the carbazole moiety is enhanced. The n-alkyl methacrylate polymers with a pendant carbazole ring spaced n ≥ 9 exhibited a lower activation energy and temperature for the onset of ring motion and resulted in polymer-based memristors that exhibited electrical characteristics, such as incrementally adjustable conductivity and are potential candidates for mimicking synaptic plasticity. © The Royal Society of Chemistry 2018. en
