a Charge-density isosurfaces for the interaction of MFM-300(In) framework with (left) P4 molecules; (right) double helices of (P8)n. Yellow represents the accumulation and blue the depletion of the electron density. Indium atoms are shown pink, C – brown, O – red, P – pale violet, H – pale brown. The DFT results are visualised using the VESTA code; b EDX mapping images of In and P in P4@MFM-300(In) (left) and (P8)n@MFM-300(In) (right); c comparison between Raman spectra of commercial red phosphorus (red), and (P8)n@MFM-300(In) (blue).
