Results and discussion General photophysical properties As expected, these cruciforms show the same absorption and emission spectra (Fig. 1a) and fluorescence quantum yields (F ¼ 10–12%) in THF solution because of their identical conjugated skeletons, indicating the N-alkyl chain lengths do not substantially affect their solution photophysical properties. However, it is noted that the F values of FCn in THF solution are obviously higher than those of the linear 9,10-distyrylanthracene derivatives whose solutions are weak or non-fluorescent. This implies that the non-radiative decay caused by the free intramolecular torsion of the two styryl moieties at the 9,10-positions of the anthracene core has been depressed in the cruciform configuration. As a result, FCn may show a weak AIE effect in aqueous media. This is evidenced by the emission spectra and uorescence images of FC4 in THF solution and a THF–water (1/9) mixture (Fig. 1b). The emission spectrum in aqueous media is slightly blueshifted relative to that in THF solution, and the ϕ value in the aqueous dispersion is only about twice that in THF solution (inset in Fig. 1b) |

結(jié)果與討論 一般光物理性質(zhì)。如所預(yù)期，在THF溶液中這些cruciforms具有同樣的吸收光譜和發(fā)射光譜（圖1A）和熒光量子產(chǎn)量 (F ¼ 10–12%)，因為他們的共軛骨架是相同的，表明N烷基鏈長度對它們在液相中的光物理性質(zhì)沒有實質(zhì)性影響。 但應(yīng)當(dāng)注意的是，在THF溶液中FCN的F值明顯高于線性9,10 - 二苯乙烯基蒽衍生物，后者在液相中呈弱熒光或無熒光。這意味著，蒽核的9,10位的兩個苯乙烯基團(tuán)分子內(nèi)的自由扭轉(zhuǎn)引起的非輻射衰減在十字形結(jié)構(gòu)中被抑制。其結(jié)果是FCN在液相介質(zhì)中可能具有弱AIE效應(yīng)。這是通過FC4在THF溶液和THF-水（1/9）混合物中的發(fā)光光譜和熒光圖像證實的（圖1b）。在液相介質(zhì)中的發(fā)射光譜比在THF溶液中稍微向藍(lán)偏移，并且在液相分散φ值大約只是在THF溶液中的兩倍（圖1b內(nèi)的插圖） |
