The present invention relates to one kind of composite light emitting materials comprising compound formed with porphyrin ligand and metal platinum and inorganic mesoporous molecular sieve, and the application of these materials in oxygen sensing. Through dispersing and dissolving the mesoporous molecular sieve with the organic template agent eliminated in solvent; adding the compound formed with porphyrin ligand and metal platinum into the solution with the weight ratio between the compound and the mesoporous molecular sieve being 1-8 to 100; stirring to react for 1 hr; filtering; washing the solid product with the solvent the same as that in the mother liquid for 3-6 times and naturally drying in the air, the composite light emitting materials may be prepared. The materials are light purple and can emit light with peak wavelength of 630-680 nm under the irradiation of ultraviolet lamp.

The invention belongs to the technical field of chemical analysis and detection, and relates to synthesis and application of a fluorescent probe for detecting trace water in dimethyl sulfoxide. The Mn-TCPP (BPDC) material can be prepared from porphyrin and manganese ions through a simple solvothermal method, and the material has relatively strong fluorescence response to water, has no response to an organic solvent dimethyl sulfoxide (DMSO) and has relatively good fluorescence linear range response to the water content in the DMSO. The fluorescent probe is simple and convenient to prepare, and has the advantages of high sensitivity, large linear range, good stability and repeatability and the like when being used for detecting moisture.

The present invention relates to the use of complexes of water soluble porphyrins of formula (I). The present invention relates to water soluble porphyrins of formula (I), wherein R₁ to R₁₁ and R₁′ to R₈′ are as defined in claim 1, their iron complexes, use thereof as catalysts for the selective electrochemical reduction of CO₂ into CO, electrochemical cells comprising them, and methods for reducing electrochemically CO₂ into CO using said complexes or said electrochemical cells, thereby producing CO or syngas.

The invention discloses an application of porphyrin in tin in preparation of medicines for treating thalassemia, which uses porphyrin in tin for intraperitoneal injection of beta thalassemia mice, and finds that porphyrin in tin can enable invalid red systems of thalassemia mice to return to normal, so that alpha/beta globin chain imbalance of red blood cells is effectively relieved, and the curative effect of thalassemia is improved. The red blood cell life, the total red blood cell number and the hemoglobin level are improved; meanwhile, the iron content and splenomegaly of serum and liver are reduced. After porphyrin in tin is used for treatment, invalid hematopoiesis, anemia and iron overload of thalassemia mice are effectively relieved, no obvious toxic or side effect exists, treatment is convenient to implement, and the curative effect can be kept only by maintaining low dosage after high dosage.
