A variety of organic optoelectronic materials based on the intramolecular charge-transfer interactions will be synthesized by using the click-type reaction between electron-rich alkynes and strong acceptor molecules.
Nonlinear optical effects of donor-acceptor type molecules as well as photovoltaic performance using p-type conjugated polymers and n-type fullerenes can be improved by controlling the chemical structure of electron-rich alkynes and the addition amount of acceptor molecules.
