Constructing polymers towards ultrathin nanosheets with dual mesopores and intrinsic photoactivity

We developed ultrathin dual-mesoporous polymer nanosheets by combining co-assembly of different templates with in situ synthesis of functional polymers, which featured inherent smaller and template-directed larger mesopores (2.6 nm and 15 nm, respectively), ultrathin nanolayers (20 nm), high surface area (268 m 2 g −1 ), intrinsic fluorescent properties and effective detectability for organophosphates. Ultrathin dual-mesoporous conjugated polymer nanosheets were exploited, which exhibited inherent fluorescence-based photoactivity and effective detectability for organophosphates.
