A series of 9,9'-bifluorenylidene-based conjugated microporous/mesoporous polymers (BF-CMPs) were constructed via Suzuki polycondensation. The porosities and electronic properties of BF-CMPs can be readily tuned by selection of proper monomers. Among three BF-CMPs, Py-BF-CMP exhibited an extraordinarily high adsorption capacity (1905 mg g(-1)) and excellent photocatalytic degradation performance of organic dyes in water. Moreover, Py-BF-CMP featured good recyclabiity with both high adsorption degree (99%) and photodegradation efficiency (92%) of RhB even after 10 recycles.
