The molar heat capacities of one-three-dimensional metal-organic frameworks Al4(OH)2(OCH3)4(H2N-BDC)3 (CAU-1) were measured by temperature-modulated differential scanning calorimetry (TMDSC) over the temperature range from 213 to 393 K for the first time. No phase transition or thermal anomaly was observed in the experimental temperature range. The fundamental thermodynamic parameters such as entropy and enthalpy relative to 298.15 K were calculated based on the experimentally determined molar heat capacities. The compound was characterized by elemental analysis, powder XRD, FT-IR spectrum. Moreover, the thermal stabilities and decomposition mechanisms of hydrated phase and dehydrated phase of CAU-1 were investigated by thermogravimetric spectrometer in the temperature range 298-1023 K.

The molar heat capacities of one-three-dimensional zeolitic imidazolate frameworks Zn(C4H6N2)2 (ZIF-8) were measured by temperature-modulated differential scanning calorimetry over the temperature range from 213 to 423 K for the first time. No phase transition or thermal anomaly was observed in the experimental temperature range. The fundamental thermodynamic parameters such as entropy and enthalpy relative to 298.15 K were calculated based on the experimentally determined molar heat capacities. The compound was characterized by powder XRD and FT-IR spectroscopy. Moreover, the thermal decomposition characteristics of ZIF-8 were investigated by thermogravimetry spectrometer (TG).

The molar heat capacities of one-three-dimensional metal-organic frameworks (MOFs) CrF(HO)O(BDC) (Cr-MIL-101) were measured by temperature-modulated differential scanning calorimetry over the temperature range from 253 to 413 K for the first time. No phase transition or thermal anomaly was observed in the experimental temperature range. The fundamental thermodynamic parameters such as entropy and enthalpy relative to 298.15 K were calculated based on the experimentally determined molar heat capacities. The compound was characterized by atomic absorption spectrometer, elemental analysis, powder XRD and FTIR spectrum. Moreover, the thermal decomposition characteristics of Cr-MIL-101 were investigated by thermogravimetry-mass spectrometer (TG-MS). Three stages of mass loss were observed in the TG curve. TG-MS curve indicated that the oxidative degradation products of Cr-MIL-101 are mainly HO and CO. [ABSTRACT FROM AUTHOR]
