Nonconventional luminophores with unprecedented efficiencies and color-tunable afterglows

Abstract

Nonconventional luminophores without significant conjugations generally own excitation-dependent photoluminescence (PL) because of the coexistence of diverse clustered chromophores, which strongly implicates the possibility to achieve color-tunable PL and/or persistent room temperature phosphorescence (p-RTP) from their crystals assisted by effective intermolecular interactions. Compared with traditional luminogens, however, nonconventional luminophores generally suffer the poor PL efficiency. Here, inspirited by the highly stable double-helix structure and multiple hydrogen bonds in DNA, we report a series of planar or twisted nonconventional luminophores based on hydantoin (HA), which demonstrates unprecedentedly high PL/p-RTP efficiencies and p-RTP lifetimes of up to 87.5%/21.8% and 1.74 s, respectively, accompanying color-tunable p-RTP from sky-blue to yellowish-green. These findings surely advance the exploitation of efficient nonconventional luminophores, and provide deeper mechanism insights into the origin of color-tunable p-RTP.
