Caption

 (a) PL spectra and PL micrographs (inset) of [BPP]SbCl5 upon compression. (b, c) Rietveld refinements of ADXRD at 1 atm and 7.2 GPa. (d, e) Δd values (distortion in the bond length) and σ2 values (variance in the bond angle) of [SbCl5]2− units within [BPP]SbCl5 under pressure. (f) Images of DMF-induced [BPP]SbCl5 ([BPP]SbCl5-DMF) under white light and ultraviolet light. (g) Absorption, PL, PLE spectra and chromaticity coordinates of [BPP]SbCl5-DMF. (h) Reversible emission switching cycles of [BPP]SbCl5 via DMF and heat.
