Notes:
In this report we describe the coating of delonized glass surfaces with commercially available CH3O-terminated diphenyl-dimethylpolysiloxane (PS-090). This new type of reactive, high temperature stable stationary phases withstands temperatures up to 430°C. As already reported for OH-terminated polymers, the underlying stabilization process is a condensation of methoxy groups of the phase with surface silanol groups arising from high temperature silylation. The good selectivity of this medium polar coating for substrates bearing π-electron systems is demonstrated by the separation of various metalloporphyrins.
