Synthesis of Porphyrin-Containing Hydrogels under Microwave Radiation Conditions

摘要

The synthesis of new functional hydrogels on acrylamide and tetra-aryl-substituted porphyrins with N,N???-methylenebis-acrylamide and the study of their physical and chemical properties are described, the hydrogels being synthesized at different ratios of initial components under microwave conditions. Electron spectroscopy and scanning electron microscopy were used to characterize the hydrogels obtained; their sorption properties being also investigated. Best sorption properties were shown by hydrogels containing mono-meso-allyloxy substituted porphyrin. The values of the gel fraction, the swelling degree and the water content in the hydrogels were established to be significantly affected by the amount of crosslinking agent used in the hydrogels synthesis.
