Claims21
A metal-organic framework (MOF) comprising a repeat unit of the formula Zn4(OH)2(1,2,4-BTC)2, wherein 1,2,4-BTC is benzene-1,2,4-tricarboxylate.
A method of storing a compound within a metal-organic framework (MOF) comprising:
- (a) obtaining MOF comprising a repeat unit of the formula Zn4(OH)2(1,2,4-BTC)2, wherein 1,2,4-BTC is benzene-1,2,4-tricarboxylate;
- and
- (b) combining the MOF with a first compound such that the first compound is stored within the MOF.
A method of detecting a compound using an MOF comprising:
- (a) obtaining a MOF comprising a repeat unit of the formula Zn4(OH)2(1,2,4-BTC)2, wherein 1,2,4-BTC is benzene-1,2,4-tricarboxylate;
- (b) combining the MOF with a first compound such that the first compound enters the MOF to form an MOF•guest complex;
- and
- (c) comparing the luminescence intensity of the MOF with the luminescence intensity of the MOF•guest complex so as to detect the first compound.
A method of separating two or more compounds using an MOF comprising:
- (a) obtaining a metal-organic framework (MOF) comprising a repeat unit of the formula Zn4(OH)2(1,2,4-BTC)2, wherein 1,2,4-BTC is benzene-1,2,4-tricarboxylate;
- (b) combining the MOF with a mixture comprising a first compound and a second compounds;
- and
- (c) separating the two or more compounds based on their differential diffusion rate within the MOF.
