Pyrene‐Based Polyimide Covalent Organic Framework with Temperature‐Dependent Fluorescence (Advanced Optical Materials 14/2023)

Abstract

PEPy‐COF, a new covalent organic framework (COF), exhibits a shiny blue fluorescence under UV and visible light. In article number 2300412, Amin Zadehnazari, Alireza Abbaspourrad, and colleagues built PEPy‐COF via a one‐pot condensation reaction using perylene and pyrene building blocks. PEPy‐COF features temperature‐dependent and solvent‐independent fluorescence and a semiconductor band gap making it an excellent candidate for temperature sensing devices.
