Multicolor Macromolecular Architectures by Multiple Click Reactions

通过富电子炔和氰基受体之间的高产加成反应，合成了各种各样的彩色有机聚合物。成功地合成了红、黄、蓝三原色，因此，人们认为这种合成聚合物基有机染料和颜料的新方法在工业上具有很高的用途。此外，结合使用其他有效的加成反应，可以以非常高的收率生产复杂的大分子结构。此外，当氰基受体加入到整合成共轭聚合物的富电子炔中时，前驱体聚合物的能级降低。这一结果表明聚合物的特性从p型转变为n型半导体。

A wide variety of colorful organic polymers are synthesized by using high-yielding addition reactions between electron-rich alkynes and cyano-acceptors. The three primary colors of red, yellow, and blue are successfully constructed, and accordingly, it is thought that this new synthetic method for producing polymer-based organic dyes and pigments is highly useful in industry. Also, the combined use of other efficient addition reactions allows for the production of complex macromolecular architectures in remarkably high yields. Furthermore, when cyano-acceptors are added to the electron-rich alkynes integrated into conjugated polymers, the energy levels of the precursor polymers are lowered. This result suggests the conversion of the polymer characteristics from p-type into n-type semiconductors.
