Preparation of Highly Ordered Mesoporous Thiophene-Silica with Spherical Macrostructure
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 EO<SUB>16</SUB>(L<SUB>29</SUB>G<SUB>7</SUB>)EO<SUB>16</SUB> template were observed to have a well-defined spherical-like external morphology with a diameter of 2–5 μm, and a 2D hexagonal (<I>p</I>6<I>mm</I>) 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<SUP>2</SUP> g<SUP>−1</SUP>.
