研究目的
Investigating the synthesis, deposition, and doping of multiply fused porphyrin oligomers using an oxidative chemical vapor deposition (oCVD) approach for potential applications in optoelectronic devices.
研究成果
The one-step synthesis, deposition, and doping of multiply fused porphyrin oligomers was achieved using an oCVD approach. The technique allows for the deposition of conductive poly(porphyrins) thin films on various substrates, including sensitive and flexible ones like paper, paving the way for future applications in optoelectronic devices.
研究不足
The insolubility of the oCVD NiDPP coating prevents GPC analysis, and the limited range of observation of LDI-HRMS does not allow to assess any polymerisation length. Side reactions such as porphyrin chlorination and π extension via intramolecular ring fusion occur.
1：Experimental Design and Method Selection:
The oCVD reaction was performed under reduced pressure in a customized stainless steel reaction chamber equipped with two crucibles for subliming NiDPP and FeCl
2：Sample Selection and Data Sources:
Printer paper sheets, microscope glass slides, silicon wafers, and commercial organic field-effect transistor chips were used as substrates.
3：List of Experimental Equipment and Materials:
A customized stainless steel reaction chamber, heated crucibles, and a heated stage were used.
4：Experimental Procedures and Operational Workflow:
The substrates were placed on a heated stage above the crucibles, and the oCVD reaction was performed to yield thin films.
5：Data Analysis Methods:
UV-Vis-NIR spectroscopy, LDI-HRMS, GPC, SEM, AFM, and conductivity measurements were used for analysis.
