Abstract: Aspects of the disclosure feature a method that comprises preparing an agent-cyclodextrin complex. Preparing the agent-cyclodextrin complex includes contacting a first composition comprising an agent with a porous cyclodextrin-metal organic framework to form a second composition comprising an agent-cyclodextrin-metal organic framework complex, the cyclodextrin-metal organic framework including a plurality of cyclodextrin molecules and at least one metal cation. Preparing the agent-cyclodextrin complex also includes dissolving the agent-cyclodextrin-metal organic framework complex in an aqueous solvent to form a third composition including the agent-cyclodextrin complex.

Abstract: This disclosure relates to a composition that includes an active agent and a porous cyclodextrin-based metal organic framework (CD-MOF). The CD-MOF includes at least a metal cation and a plurality of cyclodextrin molecules. The composition includes from about 0.05 mg to about 0.5 mg of the active agent per 1 mg of the CD-MOF. Methods of preparing and using the compositions are also disclosed.

Abstract: This disclosure relates to methods of isolating CDs. The method includes contacting a CD production mixture containing ?CD, ?CD, ?CD, and CD production byproducts with a metal salt; and forming CD-MOF complexes containing at least a metal cation and a plurality of CD components.

Abstract: This disclosure relates to a composition containing a fragrance and a porous cyclodextrin-based metal organic framework (CD-MOF). The CD-MOF includes at least a metal cation and a plurality of cyclodextrin molecules.

Abstract: This disclosure relates to a method that includes (1) contacting a solvent with a porous cyclodextrin-based metal organic framework (CD-MOF) adsorbed with CO2 to release CO2, and (2) collecting the released CO2. The CD-MOF includes at least a metal cation and a plurality of cyclodextrin components.
