Nucleophilic addition of carbon-centered nucleophiles to nanographene ketones represents a valuable late-stage method for the functionalization zigzag nanographenes, but its use is rare in chemical literature. Using two model systems, non-Kekulé triangulene-4,8-dione and Kekulé anthanthrone, we identify unexpected regioselectivities uncover rules that govern these reactions. Considering large n...

By using molecular dynamics simulations we demonstrate that at high P\'eclet numbers a nanographene suspended in shear flow aligns constant orientation angle, contrast with the rotary motion predicted by Jeffery's theory. This instantaneous alignment of is due to hydrodynamic slip fluid-particle interface, and produces marked reduction suspension viscosity compared no-slip case.

Different electronic effects in the starting anthracene-containing polyphenylene substrate (bottom) afford two different nanographenes under Scholl reaction conditions, namely spironanographenes (R=H) on left and a helically arranged molecular nanographene having orthogonal aromatic moieties linked by an octafluoroanthracene core (R=F) right. The stabilities of intermediate trityl cations conco...

The objective of this work is to evaluate the corrosion behaviour nanographene oxide reinforced aluminium (Al/GO) metal matrix composites with different immersion time periods using technique. Al/GO were fabricated by ultrasonic gravitational stir casting process. corrosions evaluated a scanning electron microscope. experimental results revealed that rate decreased and weight losses increased i...
