Considering the widespread interest in the chiroptical properties of materials, especially
circularly polarized luminescence (CPL), the functionalization of bipyrenol (BPy)
was carried out aiming at future advanced chiral materials (ACMs) in which BPy shows
a high quantum yield and clear CPL spectra. To create ACMs using BPy units that contain
nucleophilic substituents, amine and thiol were selected as the functional group and
attached to BPy by means of alkyl linkages. The obtained thiol and amine derivatives
are stable under ambient conditions. To demonstrate the potential of these molecules,
photoinduced electron-transfer systems were synthesized.
