Problems solved by technology

If you use inert gas to remove oxygen, it will cause a large number of bubbles in the system, and the time for ventilation and deoxygenation will be long (2-3 hours); although the time is short when using sodium sulfite to remove oxygen, the conditions are harsh, and generally need to be in neutral or weakly acidic conditions and the addition of heavy metal ions will lead to environmental pollution

Abstract

The invention discloses a hybrid supermolecule room temperature phosphorescent material and a preparation method thereof. The material is prepared through adding Pd-TCPP into DBS supermolecule gel hybridized by a gemini surfactant. The material can obtain high-intensity room temperature phosphorescence; more importantly, in the material preparation process, the additional addition of deoxygenization or heavy metal addition is not needed; a simple and convenient method is used for obtaining the room temperature phosphorescent material. Compared with the non-hybrid supermolecule gel not adding the gemini surfactant, the material adapts to a wider luminous pH range which can reach pH 2 to 7. The material is hopeful to be used in the fields of sensors and anti-counterfeiting materials.

Description

technical field [0001] The invention belongs to the field of luminescent materials, and in particular relates to a hybrid supramolecular room temperature phosphorescent material and a preparation method thereof. Background of the invention [0002] Due to the larger Stokes shift and longer lifetime of phosphorescence, it can avoid the interference of excitation light, short-lived fluorescence and scattered light, and obtain lower detection limits. In order to control the non-radiative transition of phosphorescent molecules, obtaining phosphorescence usually requires low temperature conditions, which greatly limits the application of phosphorescence. The later developed room temperature phosphorescence is widely used in the fields of life science, environmental science, clinical medicine and industrial energy because its luminescence no longer requires harsh low temperature conditions. Room temperature phosphorescent materials usually need to remove oxygen to prevent phospho...
