Abstract
Achiral and chiral isomers of dipyrenoheteroles were
synthesized via alkyne benzannulation. The electronic properties of
these compounds were examined using cyclic voltammetry and
differential pulse voltammetry. The enantiomers of the chiral isomers
were separated, and their optical properties were examined in circular
dichroism and circularly polarized luminescence studies. The chiral
isomers exhibited a large bathochromic shift, relative to the achiral
isomer, in both absorbance and fluorescence, resulting from
decreased symmetry, rather than a change in the size of the
backbone.
