Synthesis of meso-substituted porphyrins as precursors in creating highly ordered electroluminescent polymer materials

Methods of obtaining porphyrin-containing polymer materials that have electroluminescent properties are analyzed. Based on the data, a strategy for producing the most effective porphyrin precursors for the further synthesis of highly ordered polymer materials is developed. Synthetic approaches are found and two meso-substituted porphyrins, i.e., 5,15-diphenyl-10,20-dibromoporphyrin (1a) and 5,15-diethynylphenylporphyrin (2a), are synthesized.
