“…The main application of MPc's is the production of organic light emitting devices (OLED) where they perform the role of holes injection layes [3]. Due to the semiconducting properties of MPc's, they are also attractive for photodetectors, organic transistors, sensitive gas sensors, flexible solar cells [4,5], non linear optics [6], photodynamic therapy [7], basis for the optical sensing [8], as carrier generation materials in near infrared [9] and optical data storage systems [10].…”
