Absorption spectra indicate that there is little or no interaction between chromphores in the ground state. However, the fluorescence emission of oxadiazole and triphenylamine moieties are almost quenched, which shows that in the excited ground state there exists very effective intramolecular singlet-singlet energy transfer .

研究发现，这些多发色团化合物在基态发色团之间没有作用或作用很小，而其中噁二唑和三苯基胺单元的荧光被严重的猝灭，这说明在激发态下，萘酰亚胺发色团与噁二唑、三苯胺功能团之间发生了分子内单线态—单线态能量转移。
