Abstract:X‐ray imaging utilizing organic–inorganic hybrid metal halide (OIHMH) glassy scintillators has garnered significant attention. But their inferior radioluminescence makes achieving rapid image acquisition difficult, posing a persistent challenge for dynamic imaging. Herein, organic phosphonium halide side‐chain engineering is proposed, introducing bulky aromatic rings at the alkyl chain ends, to improve the radioluminescence of OIHMHs. For Mn(II)‐based OIHMHs, the (BUP)2MnCl4 (BUP = butyltriphenylphosphonium) p… Show more
