  • In this paper, the electrochemical behavior of Viologen self assembly monolayer has been investigated with QCM, which has been known as nano-gram order mass detector. The self assemvly process of Viologen was monitored using resonant frequency $({\Delta}F)$ and resonant resistance(R). QCM measurements indicated a mass adsorption for Viologen assembling on the gold sufrace with a frequency change about 135[Hz] and calculated its surface coverage($\Gamma$) to be $3.5273{\times}10^{-9}[mol/cm^{2}]$. Also reversible redox process was observed and analyzed with ionic interaction at the Viologen/solution interface using ${\Delta}F$.

  • We describe a unique process based on colloidal self-assembly that results in a uniform (almost hexagonally close-packed) layer of liquid crystal domains over large areas leading to single-substrate cholesteric LCDs with low switching voltages, excellent contrast, and high brightness. Extension to guest-host LCDs is also discussed.
