Emissive supramolecular metallacages via coordination-driven self-assembly

The development of luminophores with favorable photophysical properties is highly demanding for chemical probing, biological sensing and imaging, optoelectronic materials, and theranostic agents. Light-emitting metallacages constructed by coordination-driven self-assembly represent a promising platform due to their high synthetic efficiency and structural versatility, which enable facile control over their photophysical properties. Scientists based in China and the United States summarized the latest advances in the field of light-emitting metallacages and outlined future development challenges.
