Abstract

Abstract:

Metallophthalocyanines are known not only as classical dyes in practical use but also as modern functional materials. However, detailed preparation of chloroindium phthalocyanine wasn′t reported up to the present. In this paper, chloroindium phthalocyanine was synthesized by the solid reaction of urea, phthalic anhydride, molybdic ammonium with hydrated indium trichloride using acetic sodium as catalyzer. The structure was verified by elemental analyst, UV-Vis, IR and XRD. Molar ratio of materials, catalyzer, reaction temperature and reaction time were discussed on the effect of yield of chloroindium phthalocyanine, so the optimal conditions were summarized as follows: n(urea)∶n(phthalic anhydride)∶n(indium trichloride)=14∶4.5∶1, acetic sodium was used as catalyzer. Firstly, reaction mixture was kept at 130 ℃ for 0.5 h, and then the reaction was carried out at 220 ℃ for 4 h. 88% H₂SO₄ was used to purify the product. In addition, the photosensitive properties of photosensitive resistance films were also studied. It was found that when 0.2 g chloroindium phthalocyanine and 0.6 g PVB were used to prepare photosensitive resistance films, the optimal dosage of dispersant butanone-cyclohexanone is 36 mL. The resistance sensitivity and integral ratio sensitivity of the chloroindium phthalocyanine films were over 1.50×10⁸ and 30 μA/(lx·V), respectively. These results show that chloroindium phthalocyanine films have good photosensitive properties.
