| 研究開始時の研究の概要 |
This research proposal aims to investigate the synthesis and properties of N-doped ladder polymers (LP) which are predicted to possess outstanding properties. Traditional synthesis methods have proven challenging in producing defect-free LPs. In this study, we propose an innovative approach to synthesize LPs within the nanochannels of Metal-Organic Frameworks (MOFs). The nanoconfinement is expected to regulate the reaction and facilitate the formation of defect-free LPs. Upon that, we will explore methods for processing the material and investigate its physical properties.

| 研究実績の概要 |
It was reported by using the nanoconfinement of nanochannels, defect-less regulated conjugated ladder polymers (CLP) could be synthesized. These CLPs showed promising characters for organic semiconductor devices. However, the processing is difficult because of low solubility.
On the base of previous work, methods for the dissolution and processing of CLPs were studied. Deep eutectic solvents (DES) were utilized, and dissolution of CLP from PAN and BBL were dissolved for the first time. The CLP in DES solution displayed unique physical properties compared to the solid state. Electrodeposition was applied for deposition of CLP on the ITO glass, and the morphology of thin film can be controlled by varying the concentration and scanning speed. This method is meaningful for the fabrication of high-performance organic semiconductor devices using the CLPs.
