Large π-conjugated systems are key in the
area of molecular materials. Herein, we prepare via AuI

catalyzed cyclization a series of fully π-conjugated
anthracene-fused oligo-BODIPYs. Their structural and
optoelectronic properties were studied by several techniques, ranging from X-ray, UV/Vis, and cyclic voltammetry to transient absorption spectroscopy. As a complement, their electronic structures were explored by
means of Density Functional Theory (DFT) calculations.
Depending on the size and shape of the π-conjugated
skeleton, unique features—such as face-to-face
supramolecular organization, NIR absorption and
fluorescence as well as strong electron accepting character—were noted. All in all, the aforementioned features
render them valuable for technological applications
