Enlarged‐TriQuinoline (Enl‐TQ): Disparity in Chemical Behaviors by Geometric Scaling of the Trimeric Quinoline Ring System

open access: yesChemistry – An Asian Journal, EarlyView.
TriQuinoline (TQ), a quasi‐planar cyclic quinoline trimer in a head‐to‐tail arrangement, strongly captures a proton and exhibits unusual physicochemical properties. In this study, we designed and synthesized its expanded analog, Enlarged‐TriQuinoline (Enl‐TQ), in which three alkyne units are embedded between three quinoline units to acquire an expanded
