研究目的
To study the PhPTCD supramolecular arrangement and the thermal stability of this arrangement in PVD films.
研究成果
The PhPTCD PVD films exhibit a controlled growth, homogeneous morphological surface, and a preferential flat-on molecular organization. The supramolecular arrangement is thermally stable under the conditions tested, making PhPTCD a potential candidate for electro-optical devices.
研究不足
The study is limited to the characterization of PhPTCD PVD films under specific conditions of thermal treatment and does not explore the effects of other environmental factors or different deposition techniques.
1：Experimental Design and Method Selection:
The study involved the fabrication of thin solid films of bis(phenethylimido) perylene (PhPTCD) using the physical vapor deposition (PVD) technique (thermal evaporation). The films were deposited onto different substrates (Ag mirror, Ge, and quartz plates) for various characterization techniques.
2：Sample Selection and Data Sources:
The PhPTCD powder was provided by Dr. J. Duff from the Xerox Resource Centre of Canada. The PVD films were grown using the vacuum thermal evaporation technique.
3：List of Experimental Equipment and Materials:
The equipment used included a Boc Edwards machine (model Auto 306) for vacuum thermal evaporation, a Varian spectrophotometer (Model Cary 50) for UV-Vis absorption spectroscopy, a Renishaw micro-Raman system (model in-Via) for micro-Raman spectroscopy, a Bruker spectrometer (model Tensor 27) for FTIR absorption spectroscopy, a Shimadzu diffractometer (model XRD6000) for X-ray diffraction, and a Nanosurf microscope (model easy Scan 2) for AFM images.
4：Experimental Procedures and Operational Workflow:
The PVD films were deposited in five evaporation steps, with each step monitored in-situ by a quartz crystal microbalance. The films were characterized using UV-Vis absorption spectroscopy, micro-Raman spectroscopy, FTIR absorption spectroscopy, X-ray diffraction, and AFM microscopy.
5：Data Analysis Methods:
The data was analyzed using various spectroscopic techniques to determine the molecular organization, thermal stability, and morphological characteristics of the PhPTCD PVD films.
