A series of π-extended aromatic indenofluorene (IF) analogs with naphthalene and anthracene cores were synthesized through acid-catalyzed intramol. cyclization. The regioselectivity of the reaction is controlled by a combination of steric and electronic factors and in some cases several possible regioisomers have resulted from the same precursor. The effects of ring connectivity on the optoelectronic properties were studied by DFT calculations, absorption/emission spectroscopy, cyclic voltammetry, and spectroelectrochem. studies. All regioisomers exhibited a red shift of their absorption/emission bands relative to the parent IF analogs, but the magnitude of this shift and other optoelectronic properties (luminescence quantum yield, etc.) depends on the ring connectivity in a less obvious manner.
