Synthesis and characterization of a novel calix[4]arene-based periodic mesoporous organosilica
A new calix[4]arene-based periodic mesoporous organosilica has been synthesized using tetraethoxysilane (TEOS) and a calix[4]arene-based silane monomer as the precursors and cetyltrimethylammonium bromide (CTAB) surfactant as the structure-directing template, and is shown to be capable of visual detection and entrapment of NO2.
