17: LIQUID CRYSTAL POLYMERS 391
Less common than in GC is the application of LCP
as a stationary phase in LC [87]. Two basic methods to
prepare liquid crystalline stationary phases are avail-
able, namely:
1. Bonding low-molecular-weight liquid crys-
talline molecules to silica gel particles, or
2. Coating or bonding of LCPs onto silica.
Of course, the first method results likewise in poly-
mers as the second method, however, in the first
method hybrid materials containing inorganic and
organic materials are produced.
An acid chloride functionalized liquid crystalline
material was tried to bond to the silanol group in
silica. The direct reaction does not
