The 2D hyperbranched conjugated polymer P2 was synthesized and used as a sensor for detecting TNT.
Thermal stability, solubility, sensitivity and thermodynamic driving force of the hyperbranched conjugated polymer were improved.
The quenching speed of P2 positively correlates with the rate of electron transfer.
Hyperbranched conjugated polymers afford multi-dimensional transport pathways for exciton migration.
Quantum-chemical calculations were performed to study the binding mode of sensors and TNT.
