Porphyrin derivative-based tandem response nanochannels triggered by Zn2+ and NO

Chem Commun (Camb). 2022 Jul 21;58(59):8286-8289. doi: 10.1039/d2cc02163c.

Abstract

We describe tandem response solid nanochannels tailored with a porphyrin derivative that show Zn2+ and NO gating behaviors with good selectivity, stability, and reversibility. EXAFS and fluorescence experiments showed that zinc coordinated with the porphyrin derivative as the ratio of 1 : 1 with the binding constant for 3.39 × 105 M-1. These studies are beneficial for simulating the physiological functions of ion/gas in organisms and have the potential for designing complicated logic circuits and fabricating novel biosensors.
