Three types of bichromophoric styrylquinoline
(SQ) dyads are discussed in the review: bisstyrylquinoline
dyads, styrylquinoline-merocyanine
dyads, and styrylquinoline-naphthol dyads, in comparison
with the corresponding model monochromophoric
compounds. A variety of photochemical and photophysical
processes is observed in the dyads: photoluminescence,
reversible and kinetic-driven one-way photoisomerization,
[2+2]photocycloaddition with formation of a
single rctt-isomer of the cyclobutane derivative, Forster
resonance energy transfer (FRET) where the SQ chromophore
can act as an energy donor or acceptor. Operation
of the dyads as photoswitches and molecular logic
gates is also considered.
