Determining the origin of this Tg value is not clear-cut. Two distinct Tgs from the starting materials would be expected in a heterogenous composite with interlocked, separate domains of the individual constituents, whereas a single, new Tg value would be obtained if a homogenous blend has formed. The latter effect was observed after liquid phase mixing of ZIF-62 and ZIF-4-Co, [Co(Im)2], in which a melt-quenched glass with a single Tg distinct from either parent material was obtained, indicating the formation of a miscible blend. Previous studies on blending phosphate glasses indicate that blends consisting of different glasses produced two distinct Tgs, but these were shifted relative to the pristine glasses because of the close mixing of the two phases. Here, we suggest that the Tgs of the blends are related to the inorganic phase itself because the variable strength of the DSC signal at Tg is related to the mass fraction of this phase for constant sample mass used in the DSC studies. The agZIF-62 Tg is not present in the scans because the heating range used is lower than the Td of the 1:1 and 1:3 blends (agZIF-62 Tg > blends' Td).
