为了拓宽发光染料的应用范围，采用金属有机骨架材料作为载体，解决发光效率低、稳定性差等问题。本文通过尺寸限制和静电相互作用制备了一种双光子发光染料限制的离子型金属有机骨架（iMOF）ZJU-68 ADMASM。研究了染料负载量对发光效率的影响，发现双光子发射强度的变化与量子效率的变化一致。此外，该复合材料在20 °C ~ 60 °C范围内表现出优异的生理温度传感性能，具有较高的相对灵敏度、良好的水稳定性和良好的生物相容性，在生物领域具有很大的应用潜力。
In order to expand the application range of luminescent dye, metal-organic framework (MOF) is applied as a carrier to solve the problem such as low luminescent efficiency and poor stability. Here a two-photon luminescent dye-confined ionic metal-organic framework (iMOF)ZJU-68⊃DMASMwas prepared through size confinement and electrostatic interaction. The dye loading content was investigated to obtain maximum luminescent efficiency and it was found that the change of two-photon emission intensity was consistent with that of quantum efficiency. In addition, the composite showed excellent physiological temperature sensing performance from 20 °C to 60 °C with a high relative sensitivity, good water stability and good biocompatibility, possessing great potential to be applied in biological field.
