NIR-absorbing and emitting α,α-nitrogen-bridged BODIPY dimers with strong excitonic coupling
Chem Commun (Camb). 2024 Apr 18. doi: 10.1039/d4cc00878b. Online ahead of print.ABSTRACTThree new distinct NIR α,α-NH-bridged BODIPY dimers were prepared by a direct nucleophilic substitution reaction. The synergistic effects of the nitrogen bridges and strong excitonic coupling between each BODIPY unit play major roles in enhancing the delocalization of an electron spin over the entire BODIPY dimers. The in situ formed aminyl radical dimer showed an absorption maximum at 1040 nm.PMID:38634482 | DOI:10.1039/d4cc00878b (Source: Chemical Communications)

Exploring mitochondrial targeting: an innovative fluorescent probe reveals Nernstian potential and partitioning combination
This study introduces a paradigm-shifting approach to optimize mitochondrial targeting. Employing a new fluorescent probe strategy, we unravel a combined influence of both Nernst potential (Ψ) and partitioning (P) contributions. Through the synthesis of new benz[e]indolinium-derived probes, our findings redefine the landscape of mitochondrial localization by optimizing the efficacy of mitochondrial probe retention in primary cortical neurons undergoing normoxia and oxygen-glucose deprivation. This methodology not only advances our understanding of subcellular dynamics, but also holds promise for transformative application...
