A porous β-cyclodextrin-based terpolymer fluorescence sensor for in situ trinitrophenol detection.

ABSTRACT: Permanent porosity plays a key role in fluorescent-based polymers with "on-off" emissive properties due to the role of guest adsorption at accessible fluorophore sites of the polymer framework. In particular, we report on the design of a porous fluorescent polymer (FL-PFP) composed of a covalently cross-linked ternary combination of β-cyclodextrin (β-CD), 4,4'-diisocyanato-3,3'-dimethyl biphenyl (DL) and tetrakis(4-hydoxyphenyl)ethene (TPE). The textural properties of FL-PFP were evaluated by the gas uptake properties using N₂ and CO₂ isotherms. The BET surface area estimates according to N₂ uptake ranged from 100-150 m² g^-1, while a lower range of values (20-30 m² g^-1) was estimated for CO₂ uptake. Mod
