Abstract

The invention discloses a dual-rear-earth organic framework material for physiological temperature detection. The structural formula of the dual-rear-earth organic framework material is Tb1-xEuxL, wherein x is greater than 0 and not greater than 0.5, and L is 4,5-di(4'-carboxyphenyl) phthalic acid, 4,5-bis(6-carboxyl pyridine-3-yl) phthalic acid, 4,5-bis(5-carboxyl pyridine-2-yl) phthalic acid or 5,6-bis(4-carboxyphenyl) pyridine-2,3-dicarboxylic acid. The dual-rear-earth organic framework material is prepared by virtue of a solvothermal method, and the preparation method is simple and high in yield. The dual-rear-earth organic framework material has characteristic luminescence peaks of rear-earth europium ion and terbium ion, and the ratio between intensity of the two peaks has a relatively good linear relation with temperature, so that self-aligning detection can be realized, sensitivity is relatively high, and the temperature detecting range including a physiological temperature range is 25-75 DEG C; and moreover, the luminescence color of the dual-rear-earth organic framework material obviously changes with the changes of the temperature, so that the real-time temperature image-forming can be realized, and thus, the dual-rear-earth organic framework material is expected to be practically applied in the physiological temperature detection field.

Description

technical field [0001] The invention relates to a double rare earth organic framework material used for physiological temperature detection and a preparation method thereof. Background technique [0002] Temperature is a very common and crucial parameter in scientific research and industry, and detecting temperature in an accurate, high-resolution, non-contact manner is crucial for understanding the characteristics of optoelectronic devices (e.g., thermal conduction, thermal diffusion, thermal response, etc.) are critical. And accurate measurement of the temperature of cells, especially cancer cells, is of great significance to the research of biology and pharmacology. Since traditional contact thermometers cannot meet this requirement, non-contact thermometers have been produced. Among many non-contact temperature detection methods, fluorescent-based thermometers can be applied to fast-moving objects and sub-micron-sized objects due to their advantages of anti-electromagn...
