Stability
1) Solution Stability: Stable in polar aprotic solvents (DMF, DMSO, acetone); Degrades easily in polar protic solvents (water, ethanol), with PXRD peaks broadening and background intensity increasing
2) Thermal Stability: VT-PXRD shows the framework maintains crystallinity below 150 °C; TGA shows thermal decomposition temperature >260 °C, with final residue being CeO₂ (accounting for 46.5% of mass)

Preservation
1) Store at room temperature, in a dry and sealed condition; avoid contact with polar protic solvents such as water and ethanol
2) Activation Method: Treat at 100 °C under 10⁻² kPa vacuum (for activation before N₂ adsorption test)
Other Features
Fluorescence: NA;
Others: Has spn topology, constructed from hexacoordinated [Ce₆(μ₃-O)₄(μ₃-OH)₄] clusters and BTC linkers; N₂ adsorption shows Type I(a) isotherm with characteristic steps for filling different pores at low p/p₀
