要約(英語): We have developed the two-dimensional chemical sensor using a photoconductive polymer film. This paper presents the refined fabrication process and the characteristics of the devices. We investigated poly(N-vinylcarbazole) (PVK) and poly(2-vinylcarbazole) (2-PVK) as the photoconductive materials. Copper(II)2,9,16,23-tetra-tert-butyl-29H,31H-phthalocyanine (Bu-CuPc) was used as dopant for dye sensitization. We fabricated the devices by spin-coat method. From the results of our study, the device fabricated by using 2-PVK with Bu-CuPc showed high photoconductivity, high S/N and concentration dependence. The detection limit of K3Fe(CN)6/K4Fe(CN)6 was approximately 1nM. Moreover, it was found that the photoconductivity depended on the quantity of dopant and the thickness of the film. It was also found that the S/N depended on the flatness of the film. In future study, we will intend to perform two-dimensional measurement.
