Abstract
A novel amphiphilic chromoionophore, N-[4-(2,3,6,7,8,9,11,12-octahydro-5H-1,4,10,13,7-benzotetraoxaazacyclopentadecin-7-yl)butyl]-4-{2-[4-(N-methyl-N-hexadecylamino)phenyl]ethenyl}quinolinium bromide (Crown D), containing a D–π–A styryl dye and an aza-15-crown-5 ether group was synthesized, and successfully transferred onto an indium–tin oxide (ITO) electrode by the Langmuir–Blodgett technique. The effect of different metal cationic subphases on the π–A isotherm of Crown D was investigated. The photoelectric conversion properties of the chromoionophore LB monolayer films were studied. The results show that the photocurrent generation properties of the film strongly depend on the radius of the metal ions coordinated with the aza-15-crown-5 ring of the dye.Keywords
