Abstract:

We prepared 4′-pentylbiphenyl-4-carbonitrile (5CB)-stabilized rhodium (5CB-Rh) nanoparticles and poly(cyclodextrin) (PCyD)-stabilized rhodium (PCyD-Rh) nanoparticles. The average diameter of Rh nanoparticles stabilized by 5CB, PαCyD, PβCyD, and PγCyD are 1.2, 5.4, 6.8, and 5.2 nm, respectively. The nanoparticles were dispersed in liquid crystal 5CB to construct novel twisted nematic liquid crystal device (TN-LCD). Voltage holding ratio was measured for TN-LCD fabricated by doping PβCyD-Rh nanoparticles. The decrement of the voltage was very much reduced for that doped with PβCyD-Rh. The response time of this TN-LCD in the presence of PβCyD-Rh nanoparticles was faster than that in the absence.
