With the rise of circular economy, self-healing polymers have attracted significant attention for their longer lifespan and greater recyclability compared with traditional thermoplastics thermosetting polymers. However, addressing instability units to develop high-performance materials remains a challenge. Herein, we report series superior polyimine derivatives, biobased polyacylhydrazones (bio-PHys), via aldehyde-hydrazide condensation. The coexistence amide bonds imine bonds, which provide hydrogen bonding dynamics, imparts remarkable mechanical properties (tensile strength 103 MPa, elongation at break 180%) bio-PHys, along notable capabilities under glass transition temperature (Tg). Bio-PHys also exhibits potential scalable production, excellent processability, photoluminescence characteristics. We explored its application in adhesive-free laminated substrates thoroughly investigated aggregation-induced emission acylhydrazone group. Furthermore, utilized bio-PHys create recyclable smart paper anticounterfeiting dynamic information storage. This work presents novel approach developing

Abstract The persistent luminescence (PersL) induced by X‐rays in fluoride materials has garnered widespread application within the field of optoelectronics. However, complexity trap systems multi‐component impeded further exploration into PersL properties. Here, a compound consisting solely and lanthanide ions is focused on, which simplifies revelation mechanism under X‐ray excitation. Experimental theoretical results reveal that phenomenon primarily attributed to migration recovery processes interstitial lattice. Depending on localization ions, corresponding Frenkel defects can be classified two distinct types: those are readily self‐recoverable near matrix less likely self‐recover dopant ions. anomalous phenomena observed at temperatures do not correspond thermoluminescence spectra substantiate existence these dynamic traps. Furthermore, leveraging material's superior properties, scintillator film prepared utilized for imaging static displays. These findings provide refined understanding related defects, laying solid foundation continued development technology.
