A novel and general route to high Tg nanoporous organic thin films (see Figure) is described. The addition of reactive diluents to the thermosetting polyarylene resin creates a situation where the Tg exceeds the highest cure temperature. Hence, the sacrificial polymer used to generate the porosity can be decomposed in the glassy state, mitigating pore collapse.
