| PXRD, TD–H₂O P31, 12.5–100 mg mL⁻¹ total precursor concentration | At low concentration, ZIF-C dominated; at 25 mg mL⁻¹, 58.6 % ZIF-C and 41.4 % sod; at the highest concentration, 100 % sod |
|---|---|
| PXRD, TD–H₂O P32, 12.5–100 mg mL⁻¹ total precursor concentration | Initially 100 % ZIF-C; at 25 mg mL⁻¹, 47.8 % ZIF-C and 52.5 % dia; at higher concentrations, 100 % dia |
| PXRD, TD–H₂O P34, 12.5–100 mg mL⁻¹ total precursor concentration | 12.5 mg mL⁻¹: ZIF-C dominated; 25 mg mL⁻¹: 51.5 % dia and 48.5 % sod; 50 mg mL⁻¹: 49.7 % dia and 50.3 % sod; 75 mg mL⁻¹: 47.4 % dia and 52.6 % sod; at 100 mg mL⁻¹, sod became dominant |
| PXRD, TD–H₂O phase regions | sod was favored at HmIM > 40 wt.% and Zn²⁺ ≤ 20 wt.%; ZIF-C at 25 wt.% < HmIM < 50 wt.%; amorphous or U13 materials at HmIM < 25 wt.%. Increasing total precursor concentration increased the number of sod samples, mainly at the expense of ZIF-C samples |
| PXRD, TD–H₂O local phase series | BSA/HmIM/Zn²⁺ [10/60/30]: dia at total precursor concentration > 25 mg mL⁻¹; [10/50/40]: only ZIF-C; [20/60/20]: ZIF-C below 25 mg mL⁻¹ and sod above 50 mg mL⁻¹; [10/70/20]: ZIF-C to dia to sod with increasing total precursor concentration |
| Infrared spectroscopy | Amide I at ~1650 cm⁻¹; Zn–N stretching at ~421 cm⁻¹. The amide-I/Zn–N intensity ratio was lowest at high ligand wt.% and increased as ligand content decreased; TD–H₂O maps had broader regions of high ratios than TD–EtOH maps |
| PXRD amorphous fraction and ICP-OES-derived protein fraction | For TD–H₂O samples, the PXRD-derived amorphous fraction was systematically higher than the protein fraction, assigned to both protein and amorphous ZIF. For TD–EtOH samples with protein fraction > 20 %, the two measurements agreed, assigned primarily to protein. For 18 samples with protein fraction < 20 % at total precursor concentration ≥ 50 mg mL⁻¹, the PXRD-derived amorphous fraction was higher in both datasets |
