Dual emission of the target dyad is pressure sensitive in weakly polar solvents (see picture) and also susceptible to changes in temperature and local polarity. This behavior can be traced to the interplay between π, π* fluorescence and emission from an intramolecular exciplex. The two species exhibit comparable emission quantum yields under ambient conditions but formation of the exciplex is influenced by the local environment.
