Zusammenfassung:A titanium-mediated aza-BODIPY synthesis using diketopyrrolopyrrole bearing -anisyl substituents provided , -chelated pyrrolopyrrole aza-BODIPYs in a one-pot manner ether bond cleavage and chelation of the resulting nucleophilic oxygen to the boron atom. The , -chelation not only induces the redshifts of absorption and fluorescence but also endows chiroptical properties.
