Apparent BET surface area.
Photoluminescent emission peak of polymer recorded in the solid state.
Calculated from the onset of the absorption spectrum.
Reaction conditions: 100 mg polymer was suspended in 100 mL diethylamine/water solution (20 vol %) and irradiated by a 300 W Xe lamp (λ > 420 nm visible filter) for 6 h.
