Superficially porous organic polymer particles

Abstract

In various embodiments, the present disclosure pertains to organic polymer core-shell particles that comprise a non-porous organic polymer core (i.e., having a pore volume of less than 0.1 cc/g) and a porous organic polymer shell (i.e., having a pore volume of greater than 0.1 cc/g), in which the porous organic polymer shell has a pore size ranging from 100 Å to 3000 Å. In some embodiments, the present disclosure pertains to chromatographic separation devices that comprise such organic polymer core-shell particles. In some embodiments, the present disclosure pertains to chromatographic methods that comprise: (a) loading a sample onto a chromatographic column comprising such organic polymer core-shell particles and (b) flowing a mobile phase through the column.
