摘要: 研究了八-n-丁氧基萘酞菁铜[CuNc(OBu)8]在水亚相表面上单分子膜的形成过程,并在亲水基片上以Z型拉膜方式成功地拉制了多层LB膜.研究结果表明,八-n-丁氧基萘酞菁铜在表面压为15~50mN/m条件下可形成稳定的固态膜,其分子极限面积为0.74nm2,崩溃压为55mN/m;多层LB膜八-n-丁氧基萘酞菁铜以面对面的形式有序排列.该膜对醇类蒸气具有较好的敏感特性,灵敏度顺序为异丙醇>乙醇>甲醇,其响应范围为(1~5)×10-5(体积分数),且响应时间短(2s内),恢复快(5s内);而对氨气(体积分数1×10-4)响应时间长(30~60s),恢复慢(4~5min).

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
