Keep this handy ! Periodic mesoporous organosilica‐based compounds with chiral channels are prepared by using an achiral fluorinated surfactant (FC‐4911) and cetyltrimethylammonium bromide as structure‐directing agents. Spiral samples synthesized from 1,4‐bis(triethoxysilyl)benzene exhibit structural periodicity and a crystal‐like mesoporous wall (see TEM image).
