Recently, Professor Qu Dahui from the School of Chemistry and Molecular Engineering, ECUST, designed and synthesized a series of π-extended dihydrophenazine and tetrahydrodihydrophenazine derivatives with vibration-induced luminescence properties through direct carbon-nitrogen coupling reaction, and explored the influence of the size of conjugated molecules ‘wings’ on the stacking behavior and luminescence properties of molecular systems. The related article entitled “Vibratile Dihydrophenazines with Controllable Luminescence Enabled by Precise Regulation of π-Conjugated Wings” was published in CCS Chemistry, the flagship journal of chinese chemical society, in the form of Research Article.

The research work was mainly completed by Qiu Shuhai, a postdoctoral fellow in ECUST, and was under supervision of Academician Tian He, Professor Qu Dahui and Professor Wang Chaohui of Tsinghua University, and the distinguished researcher Zhang Zhiyun of ECUST. In addition, the research work has been financially supported by the National Natural Science Foundation of China, Frontier Science Center of the Ministry of Education of Materials Biology and Dynamic Chemistry, Shanghai Science and Technology Major Project, Shanghai Science and Technology Committee, Feringa Nobel Prize Scientists Joint Research Center, China Postdoctoral Science Fund Project, etc.
