Summary: In this study, phenothiazine-fused boron complexes were identified as promising scaffolds for ratiometric fluorescent hypochlorite probes. The synthesized complexes demonstrated ultrafast and ratiometric absorption/fluorescence changes for hypochlorite. Additionally, an endoplasmic reticulum-targeting probe was developed and showed excellent real-time imaging ability for both endogenous and exogenous hypochlorite in living cells.

Summary: A pH-sensitive fluorescent probe was created through host-guest assembly, and its fluorescence intensity was dependent on the molar ratio of the two components. The probe showed different emission properties at different molar ratios and exhibited pH-responsive fluorescence. This supramolecular probe could discriminate between different cells based on their pH-dependent fluorescence.

Summary: The photophysical properties of anthracene-appended koneramines (L-An) were analyzed and utilized as chemosensors for the detection of Cd2+ and Zn2+. The compounds showed fluorescence turn-on signals upon binding with Cd2+ and Zn2+, and were found to be potentially useful for detecting these ions inside cells. The cadmium complex also exhibited bactericidal activity and antibiofilm activity against multidrug-resistant S. aureus.
