Polar-Endcapped Short Hydrocarbon Chains on Silica

5 Polar-Endcapped Short Hydrocarbon Chains on Silica 

A long-hydrocarbon-chain RP coating such as C18 attached to the silica will require endcapping of up to 50% of unreacted silanol sites on the silica (cf. Section 13.1.1, point 5). If instead of the short -Si-(CH3)3 cap, a longer one with a hydrocarbon spacer holding a polar end group such
