Synthesizing 7-ring helicene in just two steps

“In our study, we succeeded in a two-step synthesis of 7-ring helicenes with the highest fluorescence and CPL efficiency that have been reported to date, using a commercially available reagent,” says Takanori Shibata, professor of synthetic chemistry a Waseda University.

“Helicenes have potential applications in organic luminescent materials, such as a circularly polarized luminescence (CPL)-emitting material. Because CPL-emitting material adds on much more information, there are great expectations for developments in future communication devices and 3D displays.”
