Occurrence of phosphorescence of organic compounds at room temperature in the presence of supramolecular structures based on different matrices

The works of domestic and foreign scientists for 1999-2024 devoted to the development of new methods of observation of phosphorescence of natural and synthesized chemical compounds at room temperature in the presence of various supramolecular structures and nanostructured molecular ensembles are considered. The analysis of the results of studies has shown that the occurrence of phosphorescence at room temperature in the studied systems provides the creation of either self-organizing supramolecular structures with controlled spectral properties or nanostructured molecular ensembles. These structures provide the rigidity necessary to reduce the collisions suppressing phosphorescence and prevent the radiation-free deactivation of the triplet state of phosphors both in liquid and solid solutions and on the nanoparticle surface.
