We propose a facile soft template-mediated coupling construction strategy for one-step fabrication of sandwiched mesoporous PPy/Ag nanoplates at the liquid interface, and the hybrid showed great chemical sensing performance for NH3 gas.
A two-dimensional imine-linked covalent organic framework bearing pyrene has been prepared and exfoliated in water as nanosheets to produce a stable water colloid. This COF colloid has been used to detect the presence of several organic dyes and polynitro-aromatic derivatives.
Covalent organic nanosheets (CONs) were synthesised from imide functionalised COFs. TfpBDH-CONs exhibit a "turn-on" detection capability for 2,4,6-trinitrophenol in the solid state, but show a "turn-off" detection in the dispersion state.
