A novel ionic AIE smart responsive material with multiple structural transformations.

A novel ionic liquid [TPE-Dim-DMe] (Br) was successfully synthesiszed. With the change of temperature, quadruple transformations of structure were observed in the [TPE-Dim-DMe] (Br) crystal, and it simultaneously displayed mechanochromic phenomena. In addition, its excellent solubility in water makes it a novel bioimaging agent.

A novel ratiometric AIEE/ESIPT probe for palladium species detection with ultra-sensitivity.

Existing fluorescent probes for palladium (Pd) species detection have revealed their vulnerabilities, such as low sensitivity, poor anti-interference ability and long reaction time. In order to develop a faster and more accurate detection method for palladium species at extremely low concentrations, in this study, we designed a novel ratiometric AIEE/ESIPT probe (HPNI-1) based on the Tsuji-Trost reaction for Pd. According to the data obtained, the probe was able to detect Pd species with an ultra-high anti-interference ability (Pd : other metals = 1 : 1000), rapid detection time (within 2 minute) and ratiometric fluorescent signal changes with a 1.
