In the present work, we study and compare the structure and sensing properties of thin films of unsubstituted palladium phthalocyanine (PdPc) and hexadecafluorosubstituted palladium phthalocyanine (PdPcF₁₆). Thin films of PdPc and PdPcF₁₆ were obtained by the method of organic molecular beam deposition, and their structure was studied using UV–visible spectroscopy, X-ray diffraction, and atomic force microscopy techniques. The electrical sensor response of PdPc films toward ammonia and hydrogen was investigated and compared with that of PdPcF₁₆ films. The nature of interaction between the phthalocyanines films and some gaseous analyte molecules has been clarified using quantum chemical (DFT) calculations.
