the combination of two effects: (i) the high PL quantum yield
(0.55), which increases the radiative recombination, and
(ii) the low lifetime of the generated exciton (3 ns), which
decreases its diffusion time. Thus, non-radiative decay
processes via impurities or grain defects from the different
domains24 have less chances to occur.

in the deep-red region. In-depth photophysical studies of the
dyad are on the way.
