The application discloses a SiO2-coated negative thermal expansion film and application thereof, and belongs to the technical field of temperature measurement. 12 :Nd 3+ The precursor solution is calcined to obtain the negative thermal expansion film, and then SiO2 solution is added dropwise on the negative thermal expansion film to obtain the SiO2-coated Yb2W3O 12 :Nd 3+ The SiO2-coated negative thermal expansion film is loaded on the opal template. 12 :Nd 3+ As a matrix, the SiO2 coating does not affect the luminescence of the negative thermal expansion film, and makes the Yb2W3O 12 :Nd 3+ The luminescence of the film in the near infrared is significantly enhanced. In addition, compared with the negative thermal expansion material film without the SiO2 coating, the negative thermal expansion material film is more sensitive to temperature.

The present application relates to a kind of reversible pressure-induced color change thermoplastic polyurethane elastomer and its preparation method.The reversible pressure-induced color change thermoplastic polyurethane elastomer includes, by weight parts, dihydric alcohol of tetraphenyl ethene group 50-80, diisocyanate 10-30, catalyst 0.005-0.02 and chain extender 1-10;The dihydric alcohol containing tetraphenyl ethene group is synthesized by polymerization reaction from aliphatic diacid and dihydric alcohol raw materials.The present application uses special macromolecular dihydric alcohol containing tetraphenyl ethene group as raw material to prepare pressure-induced color change thermoplastic polyurethane elastomer, after material processing and shaping, molecule free activity is limited, when material is extruded and deformed by external force, the rotation of benzene ring in tetraphenyl ethene molecule which can freely rotate is limited, the non-radiative transition mainly by rotation is reduced, molecule luminescence is enhanced, so that the material has the performance of pressure-induced color change.

The application belongs to the technical field of biotechnology, and particularly relates to a lysosome-targeting probe and a preparation method and application thereof. The structural formula of the lysosome-targeting probe is shown in formula (I). In formula (I), A is selected from an oxygen atom and a sulfur atom, R1 is selected from a hydrogen atom and an aromatic ring group, R2 is selected from a cyano group and a group shown in formula (II), R3 is selected from an aromatic ring group, and R4 is selected from a hydrogen atom and an alkyl group with a carbon atom number of 1-20. The compound of the application can specifically target lysosomes in tumor cells, emit bright fluorescence, and has a good fluorescence co-localization effect with lysosomes in tumor cells. The compound can be used for lysosome imaging, and the fluorescence intensity thereof is positively correlated with the viscosity of lysosomes in living cells such as tumor cells. The compound can be used for monitoring the viscosity change of lysosomes in living cells under various conditions. The compound can be used as a photosensitizer and a treatment sensitizer, specifically ablates tumors through photodynamic therapy (PDT), restores the sensitivity of tumor cells to radiotherapy and chemotherapy, and enhances the treatment effect of radiotherapy and chemotherapy.
