Abstract

Polarization micro-Raman spectroscopy (PMRS) shows that the spatial organization of bridge-bonded ethane, ethene, thiophene, and benzene groups housed "inside" the channel walls of oriented periodic mesoporous organo-silica film (OPMOF) is random, endowing the structure with "crystalline porosity" at the mesoscale and a "classy" organosilica framework at the microscale. The Figure shows an image of an oriented mesoporous thiophene-silica film.
