1. A method for preparing a mesoporous polymer, comprising the steps of:
- (a) providing a solution containing a polymerizable organic compound and a surfactant;
(b) allowing the surfactant to form ordered structures in the solution; and
(c) polymerizing the polymerizable organic compound to form a porous polymer having a BET surface area of at least about 50 m2/g.

Abstract
A mesoporous material prepared by polymerizing a resorcinol/formaldehyde system from an aqueous solution containing resorcinol, formaldehyde and a surfactant and optionally pyrolyzing the polymer to form a primarily carbonaceous solid. The material has an average pore size between 4 and 75 nm and is suitable for use in liquid-phase surface limited applications, including sorbent, catalytic, and electrical applications.
