Web14 hours ago · The single crystal X-ray structure of the aromatic nitro group appended benzimidazoles is discussed. • Fluorescence properties were investigated and the compounds showed red emission. • Third-order Non-Linear Optical property, studied by Z scan technique, indicated that the compounds may be used in optoelectronic devices. In chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions (orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is electrostatically repulsive. What is more commonly observed (see figure to the …
