Cover Feature: Solvent‐Sensitive Emitting Urea‐Bridged bis‐BODIPYs: Ready Access by a One‐Pot Tandem Staudinger/Aza‐Wittig Ureation (Chem. Eur. J. 69/2017)

Abstract

Urea‐bridged bis‐BODIPYs, a new family of chemically stable dyads can be efficiently obtained by a one‐pot synthetic Staudinger/aza‐Wittig ureation protocol from o‐azidomethyl meso‐phenyl BODIPYs. These derivatives outstand by a high absorption probability and excellent fluorescence emission in less polar media, which decreases in more polar media. This ureation protocol can also be employed in the conjugation of BODIPYs to amines. The cover artwork was kindly created by Guillermo Corrales. More information can be found in the Full Paper by J.
