| Research Abstract |
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.
