The odd-even effect of alkyl chain in organic room temperature phosphorescence luminogens and the corresponding in vivo imaging

Abstract

For the first time, the odd-even effect is utilized to rationally design organic luminogens with the room temperature phosphorescent (RTP) effect. Really, just simply modifying different alkyl substituents, the phenothiazine 5,5-dioxide derivatives exhibit totally different RTP properties, with the best performance achieved by CS-C3H7 having the phosphorescence lifetime up to 327 ms. Furthermore, the excitation-free phosphorescent imaging in living mouse has been successfully realized, opening up a new avenue to promote the RTP effect in purely organic luminogens as well as the corresponding application in bio-imaging.
