This talk will mainly focus on the design, synthesis and optical properties of water-soluble conjugated ladder-type quinacridone derivatives. This class of compounds are composed of an extensive π -conjugated fused-ring backbone and ionic water-soluble side chains. The rigid, coplanar, and conjugated backbone can provide superior optical and electronic properties, while side chains with ionic functionalities enable the material to be processed or functional in aqueous solution. Although there are a large number of water-soluble conjugated polymers and small molecules that have been reported, the backbone structures are mostly limited to a few well-known categories. The unique integration of ladder-type conjugated backbone designed here are expected to provide an exciting new class of exotic materials processing water-solubility properties that are conventionally not compatible with each other, enabling unprecedented applications in electronics and bio-imaging. Herein, we have constructed quinacridone derivatives by using the highly efficient “condensation followed by annulation” synthetic method developed by our group previously. The optical properties of this series of quinacridone derivatives in different solvents are also studied in order to capitalize the opportunities for application on both organic electronic and biological fields.
