圆偏振发光的开关是使用含芘的螺旋四噻唑实现的，其中两个芘荧光团以手性方式堆叠（折叠状态）。在光异构化过程中，四噻唑的几何变化可逆地控制了芘基准分子基CPL。
On-off photoswitching of circularly polarized luminescence was achieved using a pyrene-bearing helical tetrathiazole, in which two pyrene fluorophores stack in a chiral fashion (folded state). The pyrene-excimer based CPL was reversibly controlled by a geometrical change of the tetrathiazole upon photoisomerization.
