Developing a noncontact ratiometric luminescent temperature sensor with high sensitivity, widely available emission range, and reliable performance is challenge in materials science. Herein, we demonstrated that this goal can be achieved by fabricating lanthanide-functionalized hydrogen-bonded organic framework film (named the Eu@HOF-TCBP film). The unbonded carboxylic groups existed structure not only enable lanthanide ions to bind for bringing dual but also allow preparing (HOF) through facile electrophoretic deposition. obtained exhibits sensing range of 297-377 K maximum relative sensitivity 5.787% K-1 shows repeated use without loss. Moreover, material easily recycled refabricated consistent performance, demonstrating its unique merits easy recyclability regeneration as an HOF material. We believe reported strategies dual-emitting thin will open window applications.
