dc.description.abstract | A series of six azaborahelicenes with varying electron-donor substitution at the 4-position of the aryl
residue (i.e., naphthyl) or with variable π-extension of the aryl residue (thianthrenyl, anthryl, pyrenyl) was
prepared with an efficient and flexible synthetic protocol. These different types of functionalization
afforded notably pronounced intramolecular charge-transfer (ICT) character for the dyes with the strongest electron donor substitution (NMe2) or easiest to oxidize aryl residues, as evidenced by photophysical
investigations. These effects also impact the corresponding chiroptical properties of the separated M- and
P-enantiomers, which notably display circularly polarized luminescence (CPL) with dissymmetry factors in
the order of magnitude of 10−4 to 10−3
. Theoretical calculations confirm the optical spectroscopy data
and are in agreement with the proposed involvement of ICT processes. | es |
