Fig. 2 presents the emission spectrums of 2(a, b), and Fig. 3 presents the emission spectrums of 3(aei) in tetrahydrofuran solution (1 105 M). Their excitation wavelengths were all fixed at 450 nm. It can be found that their intensity ofchromophores interacted with each other in a manner leading to a red-shift of these bischromophore compounds. As shown in Table 2, the maximal emission bands were all in the range of 520e540 nm. Comparing the fluorescence of 3a with 3e, 3d with 3i, it was found that they had similar fluorescence wavelengths. Then we concluded that different carbon chain groups at N-position of 1,8-naphthalimide had little influence on the excitation wavelengths. |

不厚道，这段翻译已经不算短了，12个bb？ Fig. 2 presents the emission spectrums of 2(a, b), and Fig. 3 presents the emission spectrums of 3(aei) in tetrahydrofuran solution (1 10 5 M). 图2为化合物2的发射光谱，图3为化合物3在四氢呋喃溶液的发射光谱。Their excitation wavelengths were all fixed at 450 nm. 它们的激发波长均在450nm。It can be found that their intensity of chromophores interacted with each other in a manner leading to a red-shift of these bischromophore compounds.发色团强度相互作用，导致这些双发色团化合物光谱红移。 As shown in Table 2, the maximal emission bands were all in the range of 520e540 nm. 如表2所示，最大发射谱带均位于520-540nm范围内。Comparing the fluorescence of 3a with 3e, 3d with 3i, it was found that they had similar fluorescence wavelengths.分别比较3a和3e、3d和3i的荧光谱图，可见它们具有相似的有关波长。 Then we concluded that different carbon chain groups at N-position of 1,8-naphthalimide had little influence on the excitation wavelengths.于是我们得出结论认为，1,8-萘二甲酰亚胺N位上碳链集团的不同对激发波长几无影响。 |
