研究目的
To review azobenzene compounds that exhibit photoinduced reversible solid-to-liquid transitions, discuss their mechanisms and design principles, and explore their potential applications in various fields.
研究成果
Photoinduced reversible solid-to-liquid transitions in azobenzene-containing materials offer a novel strategy for controlling matter states with high spatiotemporal resolution, with applications in coatings, adhesives, printing, lithography, actuators, fuels, and gas separation. Future work should address issues like light penetration, use of non-UV light, and expansion to other photoswitchable systems.
研究不足
The review highlights challenges such as the limitation of light penetration due to strong absorption by photoswitchable compounds, the use of UV light which may damage materials, the thermal instability of cis isomers affecting accurate measurement of Tms or Tgs, and the need for further exploration of other photoswitchable compounds beyond azobenzene.
1：Experimental Design and Method Selection:
The paper is a review, not an experimental study, so it does not describe a specific experimental design or methodology. It summarizes existing research on azobenzene compounds and their photoinduced transitions.
2：Sample Selection and Data Sources:
The review compiles data from various studies on azobenzene small molecules and polymers, including their synthesis, properties, and applications, sourced from literature references.
3：List of Experimental Equipment and Materials:
Not applicable as it is a review; specific equipment and materials are mentioned in the context of cited studies but not detailed here.
4：Experimental Procedures and Operational Workflow:
Not applicable; the review discusses general procedures like UV/visible light irradiation for isomerization but does not provide step-by-step protocols.
5：Data Analysis Methods:
Not applicable; the review synthesizes findings from other studies without original data analysis.
