Figure S1: 1H NMR spectrum of β-CD in DMSO-d6 obtained at 295 K and 500 MHz. (The
numbering of 13C nuclei of glucose unit in the β-CD macrocycle has been shown by the
molecular structure of β-CD, see inset).
Figure S2: 1H NMR spectrum of 3-isocyanatopropyltriethoxysilane (ICL) in DMSO-d6
obtained at 295 K and 500 MHz, where * denotes the signal for DMSO-d6.
