Figure 5. STD spectra (STDoff—STDon) of substrate and Al-ITQ-HB suspensions.

Figure 5

(a) 1H NMR reference spectrum of naphthaldehyde 1a and Al-ITQ-HB suspension. (b) STD NMR of naphthaldehyde 1a and Al-ITQ-HB suspension with saturation of methyl signal (0.9 p.p.m.) of Al-ITQ-HB. All of the naphthaldehyde resonances appear in the STD experiment with equal intensity as in the reference 1H NMR demonstrating that naphthaldehyde is indeed binding to Al-ITQ-HB. (c) 1H NMR reference spectrum of nitrostyrene and Al-ITQ-HB suspension. (d) STD NMR of nitrostyrene and Al-ITQ-HB suspension with saturation of methyl signal (0.9 p.p.m.) of Al-ITQ-HB. All of the nitrostyrene resonances appear in the STD experiment with equal intensity as in the reference 1H NMR demonstrating that nitrostyrene is indeed binding to Al-ITQ-HB.
