Synthesis, structural characterization and properties evaluation of two new zwitterionic siloxane compounds

摘要

1,3-Bis(3-aminopropyl)tetramethyldisiloxane is a valuable tool for the introduction of siloxane segments into different organic-inorganic structures. This paper demonstrates how 1,3-bis(3-aminopropyl)tetramethyldisiloxane can easily form crystalline salts with different counterparts with which it comes into contact. Thus, in the reaction chamber 1,3-bis(3-ammoniumpropyl)tetramethyldisiloxane chloride and nitrate were formed in the detriment of one stage metal (Ni and Cu) complexes of Schiff's base with 4-imidazole carboxaldehyde. The salt products were isolated in crystalline state and were structurally characterized by single-crystal X-ray diffraction, elemental and spectral (FT-IR, H-1 NMR) analysis. The thermal and moisture stability as well as the aggregation ability in solution and sorption capacity for certain molecules were evaluated by adequate techniques. (C) 2020 Elsevier Ltd.
