Modification of Magnesium Silicate with 15(2)-Methyl Ester of 13(1), 17(3)-Diamino-N,N'-bis(2-hydroxyethyl)-13(1), 17(3)-dioxochlorin e(6)

摘要

Magnesium silicates modified with 15(2)-methyl ester of 13(1), 17(3)-diamino-N,N'-bis(2-hydroxyethyl)-13(1), 17(3)-dioxochlorin e(6) have been synthesized by heat treatment in water containing small fraction of ethanol. X-ray phase analysis, differential scanning calorimetry, thermogravimetry, and UV-Vis spectroscopy studies have shown that the synthesized samples contain individual molecules of 15(2)-methyl ester of 13(1), 17(3)-diamino-N, N'-bis(2-hydroxyethyl)-13(1), 17(3)-dioxochlorin e(6) held on the inorganic substrate surface by electrostatic interaction and hydrogen bonding.
