Researchers revealed the important role of intermolecular hydrogen bond in the separation and purification of structurally similar compounds

The study reveals that N,N-dimethylformamide (DMF) separates carbazole and anthracene due to strong intermolecular hydrogen bonds. Researchers used advanced liquid-state NMR techniques to analyze the interaction mechanism, finding a C=O···H-N bond between DMF and carbazole.

Review of fluorescent probes for detecting G-Quadruplex DNA

G-Quadruplex DNA structures play a crucial role in regulating genes and cell processes, but their visualization is challenging due to the dynamic nature of double standard DNA. Fluorescence-active small molecule probes have emerged as a real-time visualization method, enabling researchers to detect G-quadruplexes with high selectivity.
