Photoluminescent and Photoresponsive Iptycene‐Incorporated π‐Conjugated Systems: Fundamentals and Applications
Chun‐Wei Chiu, Jye‐Shane Yang
Abstract
Abstract Iptycene is a class of 3D, rigid, and arene‐rich frameworks and has been incorporated into photoactive π‐systems for a variety of purposes, including tuning interchromophore interactions and thus the luminescence properties, creating active sites for excited‐state host–guest interactions, controlling the planarity of the π‐backbone for exciton delocalization activity, serving as a template for gating the charge/electron/energy‐transfer or intersystem crossing efficiency, generating structural chirality for chiroptical properties, and acting as a multiblade rotator in photoresponsive molecular devices. This Review outlines these concepts with examples reported over the past two decades.
