Chemistry of Materials, Journal Year: 2024, Volume and Issue: 36(7), P. 3435 - 3443

Published: April 1, 2024

Organic–inorganic metal halides (OIMHs) can show diverse optical properties under pressure since their emission pathways be facilely manipulated through hydrostatic compression. However, pressure-induced phase transitions and irreversibility disrupt the linear tuning of pressure-dependent properties, thereby hampering applications in sensing. To improve structural stability, we introduced O–H···Br interactions synthesized a zero-dimensional (0D) manganese-based (Mn-based) OIMH, (TDMA)MnBr3(H2O)2 [TDMA = (tetrahydrofuran-3-yl)methylammonium], with 625 nm phosphorescence emission. For discoloration, high enhances crystal field splitting energy Mn2+ octahedral compression distortion, which leads to decrease band gap red shift wavelength. Above all, strong formed between adjacent octahedra have effectively improved stability suppressed pressure, promotes generation highly pressure–emission wavelength correlation. This encouraging result opens up potential sensing within 0D Mn-based OIMHs.
