β‐Isoindigo‐azaDIPYs: Fully Conjugated Hybrid Systems with Broad Absorption in the Visible Region

Abstract A one‐step synthetic pathway for the preparation of fully conjugated β‐isoindigo‐azaDIPY hybrid chromophores comprised β‐isoindigo and azadipyrromethene moieties is reported. The target compounds were characterized by spectroscopic, crystallographic, theoretical methods show unprecedented broad absorption across visible region electromagnetic spectrum. X‐ray crystal structure octa(n‐butyl)‐β‐isoindigo‐azaDIPY derivative revealed that a trans‐configuration fragment accompanies planar core.
