In the framework of a collaboration with the Gryko’s group and several other European teams, the ModES team has published a paper reporting a series of new double helicene with very valuable chiro-optical signatures. In more details, centrosymmetric N,B-doped nanographenes with strong green emission and notable circularly polarized luminescence were obtained. The developed approach involving...
