“…Fluorescence quantum yields of NB_I and NB_II are found to be 0.36 and 0.60, respectively. This is very similar to what we calculated in the case of naphthalene benzimidazole (NB_I) derivative [18][19][20]. The photophysical and electrochemical properties of naphthalene benzimidazoles (NBs) were compared to naphthalimides (NIs).…”
