Comprehensive Summary Traumatic brain injury (TBI) constitutes a cluster of disorders resulting from external physical forces that undermine the structure or function brain. TBI brings high disability and mortality rates to patients. Hence, early diagnosis is utmost importance. Current approaches mainly encompass computed tomography magnetic resonance imaging; however, there are still constraints in diagnosing due limited spatial resolution long scan durations. Herein, based on advantages low imaging background, signal‐to‐background ratio, excellent tissue penetration, sensitivity afterglow imaging, we have developed trianthracene derivative (TA)‐based nanoparticle for non‐invasive TBI. Compared with fluorescence TA‐NPs demonstrate deeper penetration depth (up 2.5 cm) higher signal‐to‐noise ratio. After injection via tail vein, can accumulate area within parenchyma achieve vivo detection short period (within 1 h), which beneficial Additionally, also accomplish precise injuries lower severity. The TA‐NPs‐based herein will significantly facilitate provide robust evidence its subsequent treatment.

Abstract In this study, a simple and rapid strategy is developed for the gram‐scale synthesis of zinc(II) halide complexes with ultralong afterglow under mild conditions. Crystalline, high‐purity are synthesized using N ‐methylbenzimidazole ( Bz ) common zinc salts (ZnX 2 , X = Cl, Br, I) as cheap industrial raw materials by stirring at room temperature atmospheric pressure. By exploiting steric effect terminal‐coordinated halogen ions to regulate arrangements ligands in structure complexes, namely cis ‐butterfly, trans cross ‐arrangement, completely differentiated stacking modes obtained. Zn(Bz)Cl ‐butterfly‐shaped arrangement has longest room‐temperature phosphorescence (RTP) lifetime (505.01 ms 298 K) long up 1.4 s. This study proposes first time use end group coordination fluorophores within resulting considerably improved RTP afterglow, thus providing new platform large‐scale afterglow.
