Abstract

Highly ordered mesoporous thiophene-silica powder was prepared using nonionic PEO-PLGA-PEO triblock copolymer templates and a 2,5-bis(triethoxysilyl) thiophene organosilica precursor under acidic conditions. The mesoporous thiophene-silica materials prepared with the EO₁₆(L ₂₉G₇)EO₁₆ template were observed to have a well-defined spherical-like external morphology with a diameter of 2-5 μm, and a 2D hexagonal (p6mm) array of mesopores with a lattice constant of 9.55 nm. The thiophene-silica also displayed a large surface area of up to 1410 m ² g^-1.
