Abstract

A pair of homochiral triple-stranded helicates [Eu<sub>2</sub>(o-<bold>L</bold><sup>RR</sup>)<sub>3</sub>](TOf)<sub>6</sub> and [Eu<sub>2</sub>(o-<bold>L</bold><sup>SS</sup>)<sub>3</sub>](TOf)<sub>6</sub> show light-responsive optical (UV and PL) and chiroptical (ECD and CPL) switching properties upon alternating UV and visible light irradiation.
