“…In such a situation, the development of a chloroform sensor is of great necessity. Up to present, various materials as chemical probes have been tested and reported for chloroform detection, such as metal–organic frameworks, , nanocomposites, , carbon black, polymers, − and organic dyes. , Among these materials, most of them suffer from many drawbacks, such as low sensitivity, poor selectivity, nonrepeatability, (Table S1) etc. Therefore, it is desirable to develop a new probe with high sensitivity, excellent selectivity, and good repeatability, as well as simultaneously visual detection for chloroform.…”
