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.

利用富电子炔与氰基受体的高产率加成反应，合成了多种彩色有机聚合物。红、黄、蓝三原色的成功构建，因此，认为这种生产聚合物基有机染料和颜料的新合成方法在工业上非常有用。此外，其他有效加成反应的组合使用允许以非常高的产率生产复杂的大分子结构。此外，当氰基受体被添加到结合到共轭聚合物中的富电子炔中时，前体聚合物的能级降低。该结果表明聚合物特性从p型半导体转化为n型半导体。
