Changing to Poly（rod-coil） Polymers： A Promising Way for an Optoelectronic Compound to Improve Its film formation

引用

Chinese Journal of Chemistry 2015年第8期33卷 847-851页

作者： Wei Shao Long Liang Xuan Xiang Hong-Jiao Li Fu-Gang Zhao Wei-Shi Li Department of Chemistry Key Laboratory of Advanced Textile Materials and Manufacturing Technology of Education Ministry Zhejiang Sci- Tech University Hangzhou Zhejiang 310018 China Key Laboratory of Synthetic and Self-assembly Chemistry for Organic Functional Molecules Shanghai Institute of Organic Chemistry Chinese Academy of Sciences Shanghai 200032 China

Good film formation is one of basic requirements for organic optoelectronic materials to achieve the capability for fabrication of large area devices. Small molecular optoelectronic compounds have a definite chemical structure and clear device performance, and thus are welcomed in the field. However, they are generally suffering from poor film formation, especially in a large area. For addressing it, this contribution proposes and demonstrates a strategy, that is, changing them into poly（rod-coil） polymers. With one optoelectronic compound [BDT（DTBT）2] and three poly（rod-coil） polymers （P1, P2, and P3） having different non-conjugated coil segments as examples, the work clearly shows that the change to poly（rod-coil） polymers keeps many basic optoelectronic properties of the refer- ence compound, including light absorption in solution, bandgap and frontier orbital energy levels, but suppresses strong intermolecular interactions and crystalline structure in film state. Further comparisons on film formation quality on glass and ITO glass illustrate that all the three polymers have a better film formation property than the reference compound.

Waterborne polymers are vital for coating industry to reduce carbon ***,formation of robust and self-healable films at ambient temperature remains a challenge owing to high energy cost of film formation *** work reports a solar-driven film formation of waterborne polyurethanes(WPUs)containing disulfide bonds via in-situ incorporation of 2D titanium carbide(MXene)with ability to convert light to *** of directly mixed with WPUs,MXene is added to join the reaction with isocyanate-terminated pre-polymer before emulsification *** approach not only prevents aggregation of MXene in water but stabilizes MXene against thermal degradation which is the key hurdle for mass production of MXene/WPU *** importantly,our results show that mechanical performance of WPU films under visible light(100 mW/cm^(2))is overwhelmingly competitive with that processed in ***,the existence of disulfide bonds in PU chains enables fast self-healing of micro-cracks under natural visible light which could vanish completely within 40 *** fractured specimens were repaired under natural visible light for 2 h,and the self-healing efficiency of tensile strength and elongation at break reached over 94.00%.
