In summary, we have successfully designed, synthesized, and thoroughly characterized a new class of chromophores based on the indoloindolizine framework. Guided by the Glidewell-Lloyd rule-which predicts that in fused polycyclic systems, larger rings tend to lose aromaticity in favor of smaller ones-we strategically merged indole and indolizine moieties into a single polycyclic aromatic system. Through targeted benzannulation, we deliberately adjusted the aromatic character of the indolizine moiety, fine-tuning the HOMO-LUMO gap by intensifying or diminishing the aromaticity of specific rings. This approach allowed us to precisely control the electronic and optical properties of the chromophores.
