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 m2 g-1), intrinsic fluorescent properties and effective detectability for organophosphates.
