Morphology controllable conjugated network polymers based on AIE-active building block for TNP detection

Three conjugated network polymers with different morphologies based on the same monomer and linker have been prepared, in the form of two-dimensional nanosheets, conjugated microporous polymers and conjugated organic frameworks. The conjugated polymers exhibit high fluorescence quantum efficiency and favorable stability, as well as obvious fluorescence quenching response to 2,4,6-trinitrophenol (TNP).
