In crystals of donor–acceptor helicene molecules, thermally activated delayed fluorescence (TADF) is strongly enhanced by the presence of occluded hexane molecules.
在供体-受体螺旋烯分子晶体中,被遮挡的正己烷分子的存在强烈增强了热激发延迟荧光(TADF)。

building block via Wittig reaction followed by photochemical electrocyclization. The helicene skeleton was substituted by a variety of O-, S-, N-, and C-centered nucleophiles using nucleophilic aromatic substitution reactions and palladium-catalyzed reactions like Suzuki coupling and Buchwald–Hartwig aminations. We have determined, using X-ray single-crystal diffraction, the crystal structures of the chloro-
