An ordered mesoporous hybrid material, with ethane-silica framework, has been prepared by a sol-gel synthesis route involving the condensation of 1,2-bis(triethoxysilyl)ethane (BTEE) under basic conditions, in the presence of octadecyltrimethylammonium bromide (ODTMABr) as a structure directing agen
for 0.5 h. The monomers 2,8-dibromo-6,6,12,12-tetraoctylindenofluorene (1) (600 mg, 0.7 mmol) and 9,10-dibromoanthracene (2) (35 mg, 0.1 mmol), dissolved in 15 mL dry and degassed toluene, were added to the above solution and the polymerization maintained at 80 C for 3 days. After cooling, the worku
