Using cocrystal engineering researchers in China have designed Flu-TCNQ cocrystal with integrated optoelectronic properties. They selected the Flu (donor) as the luminescence unit due to its good luminescence, extended π-conjugated plans, and rich electrons properties, and the TCNQ (acceptor) as the electrical building block, a typical n-type semiconductor that can provide a strong electron-withdrawing capacity. Driven by the charge transfer (CT) interaction and affected by the D-A molecules stacking mode, the emission of Flu-TCNQ cocrystal was regulated to be red, and the n-type charge transport property of the acceptor molecule was maintained in the cocrystal. According to the researchers their work provides an effective solution to the shortage of organic materials with integrated optoelectronic properties…read more. Open Access TECHNICAL ARTICLE
