英文摘要 | The biocompatible and renewable cyclodextrin metal-organic frameworks (CD-MOFs) have addressed a range of opportunities in molecular storage and separation sciences. The reported protocols for their synthesis, however, were carried out at room temperature over long time periods of time (24 h), producing crystals of relatively poor uniformity. In this investigation, micron sized gamma-CD-MOFs were synthesized by an optimized vapor diffusion method at elevated temperature (50 degrees C) within 6 h, after which the size control, crystalline stability and drug adsorption behavior were investigated in detail. In this manner, uniform cubic gamma-CD-MOF crystals were obtained when the reaction temperature was raised to 50 degrees C with pre-addition of the reaction solvent. The size of gamma-CD-MOFs was adjusted efficiently by changing the reactant concentrations, temperatures, time, gamma-CD ratios to KOH and surfactant concentrations, without influencing the porosity and crystallinity of the material markedly. Varing degrees of reduction in crystallinity and change in morphology were observed when the gamma-CD-MOF crystals are treated under conditions of high temperature (100 degrees C), high humidity (92.5%) and polar solvents (e.g., MeOH and DMF). In relation to drug adsorption by gamma-CD-MOFs, most of the drug molecules containing carboxyl groups showed relatively high adsorption (> 5%), while low adsorption (< 5%) was found for drugs with nitrogen-containing heterocyclic rings. In addition, the adsorption kinetics of captopril to standard gamma-CD-MOFs matched a pseudo-second-order model rather well, whilst captopril adsorption to the damaged gamma-CD-MOFs only partially matched the pseudo-second-order model. In summary, based upon the optimized synthesis and size control of gamma-CD-MOFs, the crystalline stability and drug adsorption characteristics of gamma-CD-MOF crystals have been evaluated as a fundamental requirement of a potential vehicle for drug delivery.
