Preparation And Gas Sensitivity of Octa-n -butoxy-2,3-naphthalocyanine Copper(Ⅱ) Langmuir-Blodgett Film

Abstract

Abstract: The formation process of monolayer of octa n butoxy-2,3-naphthalocyanine copper(Ⅱ), [CuNc(OBu)₈], on water subphase was studied. Its multilayers were successifully deposited on the hydrophilic substrates by Z-type deposition mode using LBtechnique. Stable solid film with a limiting molecular area of 0.74 nm² and a collapse pressure of 55 mN/m were formed. The LB film structure was characterized by IRand electronic absorption spectra. Macrocycle of CuNc(OBu)₈ molecules have a face to face arrangement in the multilayers. These films have good sensitivities to vapor of alcohols, with the following sequence of sensitivities: i-PrOH>EtOH>MeOH. The response time and recovery time of the LB films to vapor of MeOH, EtOH and i-PrOH[volume fraction (1-5)×10^-5 ] were within 2 and 5 seconds respectively, while those of the LBfilms to ammonia(1×10^-4) were 30-60 seconds and 4-5 minutes respectively.

Key words: Octa-n-butoxy-2,3-naphthalocyanine copper (Ⅱ), LB film, Gas sensitivity
