Photophysical parameters of the 2-APBA dimer in THF, water and its solid state.

ΦF (absolute) τ (ns) kF (s−1) knr (s−1) kF/knr
In THFa 20.1% 2.22 9.05 × 107 3.60 × 108 0.25
In water 46.6% 1.12 4.16 × 108 4.77 × 108 0.87
Solid 81.3% 4.78 1.70 × 108 3.91 × 107 4.35
a

amorphous 2-APBA dimer sample was used for preparing the THF solution.
