2,2′-Biphen[n]arenes (n = 4–8): one-step, high-yield synthesis, and host–guest properties†
Abstract
A new family of biphen[n]arenes (n = 4–8) with 2,2′-disubstituents (2,2′-BPns) has been designed and synthesized. The host–guest properties of the 2,2′-BPns have been examined; they exhibit strong binding affinities towards selected organic cationic guests.
