Vacuum deposited copper phthalocyanine thin films—structure and surface morphology

Effects of Heat Treatments on the Properties of Copper Phthalocyanine Films Deposited by Glow-Discharge-Induced Sublimation

“…In the case of the evaporated CuPc films, it should be pointed out that most authors give no particular relevance to a possible weight loss after heating at temperatures lower than 350 °C since the attention is mainly focused on the CuPc phase transformation. For this reason heat treatments are performed in nitrogen atmosphere 36,38 or in a vacuum , to prevent the effects of air or else these effects are neglected. ,, To support this belief, it must be noted that evaporated films used in these work did not undergo significant changes after heating at 250 and 290 °C in air and the decomposition of CuPc molecules with the consequent formation of CuO was not detected by XAS measurements. Moreover, thermogravimetric analyses of evaporated CuPc films showed that the 5 wt % weight loss occurred at temperatures of 416 and 423 °C in dry and humid air, respectively .…”

Influence of substrate doping on the surface chemistry and morphology of Copper Phthalocyanine ultra thin films on Si (111) substrates

“…Besides these applications, MePcs', and in particular CuPc (Copper Phthalocyanine), exhibit also very good gas sensing properties [5][6][7]. In the case of CuPc, by far the most popular amongst MePcs', most of the recent studies were focused on layers with relatively large (more than 100 nm) thicknesses [8,9]. Such "thick" CuPc films were studied in view of different applications.…”

“…Such "thick" CuPc films were studied in view of different applications. In particular, for gas sensing, careful studies were performed under strictly controlled conditions: the CuPc layers were deposited on well defined atomically clean substrates and then exposed to a selected gases [8,9]. Beyond thick films studies, there is a great interest toward the physical properties of CuPc ultra-thin films.…”

Characterisation of Langmuir–Blodgett films of new multinuclear copper and zinc phthalocyanines and their sensing properties to volatile organic vapours

“…This extraordinary versatility makes the Pc and MPc materials as attractive candidates for a wide range of potential applications such as photovoltaic cells, molecular metals, chemical sensors, nonlinear optics, and electrochromic display devices [4][5][6][7]. MPcs have attracted interest for gas sensing applications because of their high chemical and thermal stability, their ability to be deposited as thin layers, and their high intrinsic conductivity [8,9].…”
