研究目的
To focus on radical approaches that highlight confinement-entitled features of two-dimensional polymeric materials, correlating to their interface or template-assisted synthesis, structure–property relationship, charge transport properties, and future scopes for relevant practical enactments.
研究成果
The perspective delineates emergent research on 2D conducting polymers, highlighting their structure–property relationships, synthetic utility, and future prospects. Superior electronic and surface properties can be achieved with large-area, single-layered motifs, balancing charge transport, flexibility, and lateral area. Key problems in fabrication are discussed, with recent strategies to overcome them, emphasizing the potential for practical applications in electronics and catalysis.
研究不足
Limitations include challenges in achieving large lateral dimensions, mechanical stability, high-range internal ordering, defect-free crystal growth, exfoliation into single sheets, lattice mismatch between template and monomer, and difficulties in detaching polymer from templates. Current methods often result in small crystalline domains or limited scalability.
1：Experimental Design and Method Selection:
The paper discusses various synthetic methods for 2D conducting polymers, including 2D co-organization, interfacial synthesis, crystallization-induced 2D assembly, template-based self-assembly, and methodology for large-area sheet-like polymers. It emphasizes bottom-up and top-down approaches, using interfaces (liquid/liquid, gas/liquid) and templates (e.g., ice) for polymerization.
2：Sample Selection and Data Sources:
Monomers and building blocks such as boronate ester, hexaaminobenzene, triformylphloroglucinol, bipyridine-diamine, hexaethynylbenzene, aniline, and PEDOT are used. Data from literature references are cited.
3：List of Experimental Equipment and Materials:
Equipment includes TEM, HRTEM, SEM, AFM, XRD, SAED, van der Pauw method for conductivity measurements, ultraviolet-photoelectron spectroscopy. Materials include dichloromethane, water, catalysts (e.g., Cu with pyridine), solvents like 1-methyl-2-pyrrolidone.
4：Experimental Procedures and Operational Workflow:
Procedures involve synthesis at interfaces (e.g., Schiff base reaction at liquid/liquid interface), polymerization on templates (e.g., ice surface), exfoliation, and characterization steps. For example, in ice-template synthesis, aniline is polymerized on ice, followed by melting to obtain free-standing sheets.
5：Data Analysis Methods:
Analysis includes structural characterization (XRD, TEM, SAED), electrical conductivity measurements, and performance evaluation (e.g., catalytic properties).
