Abstract
pH detection is related to human beings’ life closely. Herein, a porous metal hydrogen-bonded organic framework (MHOF) Co-CDI-CO32– was designed and synthesized, which could be utilized to detect the pH values of strong acids. The sensitivity of pH detection was in the range of pH 2.0–2.4 with an accuracy of 0.1, which mainly depended on the different degree of crystal surface damage. The MHOF Co-CDI-CO32– had potential applications with the advantages of low cost, easy storage, and great sensitivity for pH detection as a pH sensor.
