Abstract
This paper reports on the development of liquid crystal for the electrochemical study of photo-induced electron transfer. This study covers the following studies: the description of the laminar liquid crystals (LLCs) system by using CPZ.HCl material, examining the lyotropic liquid crystal system of CPZ.HCl compound and its application in the photogalvanic cell. Chlorpromazine hydrochloride (CPZ.HCl) was first shown to form a lyotropic liquid crystal (LLC) when the concentrations reached > 10 M in an aqueous solution. This self-assembly was revealed through the birefringence observed through cross-polarisers and the characteristic X-ray scattering. The electrochemistry of the CPZ.HCl- LLC system was probed through the use of cyclic voltammetry using different micro-electrode materials, diameters and CPZ.HCl concentrations. Following this, this system was fabricated into a photogalvanic cell that produced a power conversion efficiency (PCE) of 0.58 %.
