Intramolecular Direct Arylation Enables Access to Diverse Photophysical Properties for π‐Expanded 1,4‐Dihydropyrrolo[3,2‐ b ]pyrroles
Dyes incorporating 1,4‐dihydropyrrolo[ 3,2‐b ]pyrrole (DHPP) units are attractive platforms for organic optoelectronics because of their tunable electronic structures and intense fluorescence. Herein, we report a modular synthetic route to a diverse family of π‐expanded DHPPs. The approach relies on double intram...
