초록

The NO$_2$ gas-detection characteristics were investigated using the functional organic Langmuir-Blodgett(LB) film of Copper-tetra-tert-butylphalocyanine(CUTBP). The optimum conditions for a film deposition were obtained through a study of $\pi$-A isotherm and the deposited film status was confirmed by ellipsometry measurements. In the NO$_2$ response experiments, first of all, the proper number of layer was obtained by a change of the electrical conductivities depending on the number of layer when the film is exposed to the gas. And response time, recovery time, and reproducibility were measured on it. On the other hand, how the NO$_2$ gas interacts to the LB film was studied by UV/visible absorption spectra.
