The exquisite combination of [In4(μ3-OH)2(COO)10(DMF)(H2O)2] clusters and H5CPDD generated a highly robust nanoporous MOF with high catalytic performance in the cycloaddition reaction of epoxides with CO2 and Knoevenagel condensation.

This paper investigates the event-triggered filter of switched positive systems subject to state saturation. First, a filter is constructed for switched positive systems. An error system is obtained by combining the switched systems and the filter. Under the event-triggering condition, the error system is transformed into an interval system. Linear programming is employed to design the gain matrices of the filter. Accordingly, the positivity and stability of the error system are guaranteed by virtue of the corresponding issues of the interval system. A cone based domain of attraction is constructed for the invariant property of the system. Finally, an example is proposed to verify the validity of the theoretical findings.

Two lanthanide metal-organic frameworks (LOFs), namely, {[Tb(L3−) (H2O)]·3CH3CN}n (1) and {(Me2NH2+)0.5·[Gd(L3−)(HCOO−)0.5 H2O]·DMF·4EtOH·H2O}n (2) have been constructed by tris(4-carboxyphenyl)phosphane oxide (H3L) under solvothermal conditions. Structural analyses indicate that complex 1 appears a 3D 6-connected {412∙63} net based on the binuclear {Tb2(COO)2} clusters. Complex 2 is also a 3D framework. Furthermore, the photoluminescence of 1 in the solid state and different solvent emulsions were studied, the results indicate that 1 shows characteristic green emission of Tb3+ ion and has better fluorescent recognition for sorts of organic solvent molecules and Fe3+ ion. Finally, the result of the variable-temperature magnetic susceptibilities suggests that complex 2 have antiferromagnetic behavior between Gd(III) ions.
