摘要：

A phenothiazine derivative PtzChol containing non-conjugated chiral cholesterol group was designed and synthesized. By analyzing the single crystal structure of PtzChol carefully, coupled with the circular dichroism (CD) signals before and after grinding, it was found that the introduction of cholesterol produced a positive effect on the production of chiral space group, on mechanoluminescence (ML) and room temperature phosphorescence (RTP), and throughout the entire light-emitting process, the CD signal could well reflect the changes of molecular arrangement.
