3.2 Spectroscopic characterization of SO2 adsorption and
desorption in M(bdc)(ted)0.5.
To unravel the nature of the interactions between SO2 molecules
and the Ni(bdc)(ted)0.5 framework upon SO2 adsorption,
we performed in-situ IR measurements of SO2 adsorption at
room temperature as a function of pressure.Since the SO2 gas
IR absorption at pressures above 100 Torr is prohibitively
high,a different procedure was employed to study the loadingsabove 45 Torr (see Figure S6).The activated sample was
exposed to the SO2 gas and the pressure cell quickly evacuated.
The IR spectra were then recorded immediately after evacuation
(acquisition time = 16 seconds).The adsorption state
could be probed because the kinetics of SO2 removal are slow
enough,as shown in Figure 3.Several SO2 associated bands,
increasing as a function of initial pressure,can be identified in
the IR spectra for Zn(bdc)(ted)0.5 of Figure 3 and Figure S7.
Two sharp bands observed at 1326 cm-1 and 1144 cm-1,exhibit
a -36 cm-1 and -7 cm-1 red-shift,respectively (from the unperturbed
values of 1362 cm-1 and 1151 cm-1 for the asymmetric
and symmetric S=O stretch modes of SO2 molecules).48-50
Although these frequency shifts are typical of physisorbed SO2
species,49,51 we will show in section 4.1 that there can be
charge transfer with the MOF.
