Propeller Chirality

Abstract

Chirality is ubiquitous in biology and chemistry. Indeed, molecular chirality plays crucial roles in biological activity. Recently, chiral materials are extensively explored for the use in 3D displays, medical endoscopes, information storage/communication, as well as studying excited-state chirality and enantioselective sensing. Among various types of chirality, propeller chirality is unique for its cooperative dynamism. In this report, we will demonstrate how the propeller chirality of hexaarylbenzenes and related molecules offers exceptional chiroptical responses derived from its dynamics.
