[2.2]Paracyclophane-dicyanorhodanine conjugates as planar chiral molecular photoswitches.

ABSTRACT: (Chir)optical molecular photoswitches have garnered significant attention for their applications in asymmetric synthesis, supramolecular chemistry, and the materials sciences. The planar chirality and associated photophysical and chiroptical properties of [2.2]paracyclophane ([2.2]pCp) derivatives have been long appreciated. Even so, chiral photoswitches incorporating the [2.2]pCp framework remain largely unexplored. Dicyanorhodanine (RCN), conjugated with oligothiophenes and pyrroles, has been recently shown as a highly competent photoisomerizable scaffold. The current work introduces a novel photoswitch system combining an electron-rich [2.2]pCp moiety with an electron-deficient RCN unit, as a planar chiral "push-pull" architecture. Single crystal X-ray study reveals the Z configu
