Novel mycophenolic acid precursor–based fluorescent probe for intracellular H2O2 detection in living cells and Daphnia magna and Zebrafish model systems Innovative for the scientific community and attracting attention in the extensive biomedical field are novel compact organic chemosensing systems built upon unique core molecular frameworks. These systems may demonstrate customized responses and may be adaptable to analytes, showing promise for potential in vivo applications.

By Youngsam Kim and Sungseo Cho, Miwon Specialty Chemical; and Rami Awad, Miwon Austria As environmental issues are becoming an industry-wide topic, the interest in water-based systems continues to rise globally. In addition to providing eco-friendly and nonflammable advantages, such systems also can be used in applications such as wood flooring, furniture, PVC flooring and others.

A new BODIPY system displaying an intramolecular ?-?-interaction was synthesized and studied. When the selenium center was oxidized, the substituted phenyl group undergoes ?-? stacking with one side of the BODIPY core. The oxidized form showed, not only a down-field shift in the NMR peak, but also splitting due to geometrical changes that arise when going from Cs to C1. The compound was characterized by X-ray diffraction; DFT methods helped elucidate the influence of the unexpected ?-?
