| titleOfInvention | High-efficiency thin-layer chromatography separation method based on metal organic framework material composite photonic crystal thin layer |
| abstract | The invention discloses a metal organic framework material composite photonic crystal (MOF-PC) thin layer and a high-efficiency thin layer chromatography separation technology based on an MOF-PC thin layer plate. As a chromatographic stationary phase, the MOF-PC thin layer has a high specific surface area and a specific microporous structure, so that a stronger adsorption and desorption effect and selectivity are shown in separation, the inherent defect of poor separation effect caused by low number of thin layer chromatographic plates is effectively overcome, and efficient separation of mixed substances is ensured. The MOF-PC thin layer also has a structural color and a reflection signal which are specific to the photonic crystal, so that the specific position of the sample can be directly determined by using the structural color difference between a sample point and the thin layer plate and the change of the reflection signal, and the chromatographic parameters such as a specific displacement value, a selection factor, a separation degree and the like can be obtained. Compared with the prior art, the technology provided by the invention has a remarkably improved separation effect, and can be used for separating substances with similar structures, which cannot be separated by the traditional thin-layer chromatography. In addition, the technology directly identifies sample points by means of structural colors, does not need additional operations such as ultraviolet irradiation, laminate dyeing and the like, and provides a new green, convenient and safe way for sample detection. |
