Abstract
Organic luminogens with room temperature phosphorescence (RTP) have garnered significant attention due to their wide application values. This study designed and synthesized eight phenothiazine 5,5-dioxide derivatives to investigate the relationship between monomer and dimer packing and RTP emission. Dimers with strong π–π stacking exhibited pure triplet excimer emission, while those with weak π–π stacking showed dual RTP emissions from both monomer and triplet excimer.
