Tuning the sumanene receptor structure towards the development of potentiometric sensors

Herein, we report for the first time the application of a sumanene derivative in potentiometric recognition of caesium cations. The structure of the sumanene receptor was carefully tuned to obtain its compatibility with polyvinyl chloride plasticized membranes of potentiometric sensors. The developed ion-selective electrodes based on membranes doped with octyloxybenzene sumanene exhibited a near theoretical sensitivity towards caesium cations, with a detection limit of 4 mu M Cs+.

Automated summary

This study reports the first application of a sumanene derivative in the potentiometric recognition of caesium cations, showing near theoretical sensitivity and a detection limit for 4 μM Cs+. The structure of the sumanene receptor was carefully adjusted for compatibility with polyvinyl chloride plasticized membranes of potentiometric sensors.
