由于取代方式的不同,使得金属酞菁衍生物数目庞大,结构各异。晶体结构的不同,造成配合物光电性能等多种性质的改变。酞菁类光敏材料研究方法有溶剂调节法,相转移法、溶胶-凝胶法、气相沉积法和真空热蒸发等,这些技术调变了酞菁衍生物的光电导性能,在光动力疗法等领域意义重大。酞菁类气敏材料对某些气体具有选择性高、响应灵敏等特点,可用于气体传感器的制作。建议进一步探讨取代金属酞菁衍生物的光敏、气敏机理,以便在分子层次上优化设计分子的结构,改善材料性能,拓宽应用范围。

Owing to different substituent types, there exist a huge amount of substituent ramification of phthalocyanine having dissimilar structures. The distinctness of crystal structure makes the photoelectric performance as well as many other characteritics of matching compound change a lot. The photosensitive materials of phthalocyanine have many preparation methods, such as solvent adjust; phase transfer; solgel, vapor deposition, vacuum sublimation method and etc, these techniques change the light electric performance of phthalocyanine ramification, which is of significant importance in the field of dynamical therapeutics. The gas sensitive materials of phthalocyanine have high selectivity, sensitive response to some gases, and they could be used for making gas sensor. It is proposed that study on the the photosensitive and gas sensitive mechanism of substituent ramification of metal phthalocyanine should be emphasized, in order to improve the performance of these materials and to widen the scope of application.
