Abstract Achieving free exciton (FE) emission in low-dimensional (2D, 1D, and 0D) metal halide perovskites is challenging due to the strong electron–phonon coupling effect induced by lead octahedral distortion. Herein, FE behaviors of three new 2D chiral perovskites, (R-3-XPEA)2PbBr4 (PEA = phenethylamine, X F, Cl, Br), were investigated under hydrostatic pressure. (R-3-BrPEA)2PbBr4 (R-3-ClPEA)2PbBr4 exhibited high color–purity deep-blue circularly polarized luminescence (CPL) dominated at pressures 1.7 2.5 GPa, respectively, whereas (R-3-FPEA)2PbBr4 presented broadband warm-white CPL The structural analysis theoretical calculation results demonstrated that pressure reduced penetration depths R-3-BrPEA+ and R-3-ClPEA+ into [PbBr6]4- inorganic frameworks strengthening halogen···halogen (Br···Br Cl···Cl) interactions between organic amines, resulting smaller distortion weaker (R-3-ClPEA)2PbBr4. Thus, pressure-driven enhancement was responsible for remarkable Conversely, could not be effectively suppressed owing lack interactions, leading absence CPL. Our work gives a insight into intrinsic structure-property relationship noncovalent ultrahigh-color-purity behavior perovskites.

Covalent-organic frameworks (COFs) are dynamic covalent porous organic materials constructed from emissive molecular building blocks. However, most two-dimensional (2D) COFs nonemissive or weakly in the solid state owing to intramolecular rotation and vibration together with strong π-π interactions. Herein, we report a pressure strategy achieve bright multicolor emission yellow red 2D triazine triphenyl imine COF (TTI-COF). Intriguingly, TTI-COF experiences 24-fold enhancement under mild of 2.7 GPa compared initial state. Joint experimental theoretical results reveal that restricted chemical bond vibrations reduced interactions originating offset stacking mode account for significant pressure-induced enhancement. Furthermore, such piezochromic behavior may be ascribed decreased energy gap enhanced intermolecular interaction. Our investigation offers constructive guidelines designing high photoluminescence performance.
