本文首次报道了外围和非外围四取代的烷硫基镓(III)酞菁的合成,液晶,光物理和光化学性质。这些新化合物的特征在于元素分析,UV-Vis,IR和11 H NMR光谱和质谱。酞菁化合物的热稳定性已经通过热重分析确定。这些新材料的介晶性能已通过差示扫描量热法,偏振光学显微镜和X射线衍射测量进行了研究。对热致行为的研究表明,所有新化合物在很宽的温度范围内都是液晶。X射线衍射图证实酞菁形成六方柱状中间相。在甲苯中研究了这些化合物的光物理性质(荧光和光降解量子产率和荧光寿命)和光化学性质(单氧量子产率)。

A series of alkylthio, alkoxy, and phenoxy phthalonitriles have been prepared by nucleophilicsubstitutionreactions on suitable phthalonitrile precursors in molten tetrabutylammonium bromide. This readily available and inexpensive ionic liquid can also be used as a medium for the cyclization of these dinitriles giving the corresponding substituted phthalocyanines.
