Recently, the organic inorganic hybrid monolithic columns have been attracting great attention.A one pot process for the preparation of organic silica hybrid capillary monolithic columns by concurrently using organic monomers and alkoxysilanes was developed.Different types of organic-silica hybrid capillary monolithic columns with hydrophobic, hydrophilic, ion exchange functionality and chiral selectors have been fabricated, respectively, by this one pot process using different types of organic monomers.It is suggested that the different porogen solvents should be adopted in preparation of the monoliths by changing the hydrophobicity of organic monomers.
