Stimuli-responsive polymers, based on their response to environmental changes. play important roles in sensor development. Sensors based on temperature-responsive polymers utilize the change in the interaction between the polymer and solvent, resulting in the aggregation of the polymer chains and the loss of transmittance of the solution at clouding point temperature (Tcp). The thermally induced phase transition behavior of the polymer is affected by various specific/non-specific interactions between the polymer chains, side/end-groups, and the solvent. In this research, we utilize the LCST behavior of poly(ethersulfone) (PES) in organic solvents to detect the hydrogenation state of benzene. We have found that the addition of benzene and its reduction products, as a non-solvent of PES, lowers the Tcp of the PES solution, and the Tcp decreases as the number of π electrons decreases, showing a linear correlation between the temperature and concentration. |
