Green Synthesis and Flexibilization Engineering of (ECMP) 2 MnBr 4 for Smart Textile‐Integrated Luminescence

Year: 2025

Type: article

Abstract: 0D hybrid manganese halides represent an emerging class of luminescent materials, yet their practical application has been hindered by the intrinsic trade‐off between optical performance and mechanical flexibility. Here, a green synthesis of 0D (ECMP) 2 MnBr 4 crystal is reported, exhibiting unprecedented triple‐mode emission (photoluminescence, X‐ray scintillation, and mechanoluminescence) through rationally designed highly symmetric [MnBr 4 ] 2− tetrahedra, achieving near‐unity photoluminescence quantum yield (98.97%), record‐low X‐ray detection limit (15.62 nGy air s −1 ) and multi‐stimuli responsiveness (rubbing, squeezing, stretching). The material's ultralow electron‐phonon coupling ( S = 1.438) and defect‐suppressing π–π stacking enable exceptional environmental stability and closed‐loop recyclability via solvent‐mediated recrystallization. Innovatively, (ECMP) 2 MnBr 4 is first integrated into thermoplastic polyurethane via wet‐spinning, simultaneously retaining single‐crystal emission intensity and achieving remarkable elasticity (>1000% strain) for deformation‐resistant wearable applications. This work establishes a new design paradigm for sustainable multifunctional optoelectronics, with immediate applications in wearable displays, high‐resolution X‐ray imaging, and self‐powered optical sensors.
