英语翻译
As shown in Fig.4,there was a significant color change from
yellow to red upon the addition of TFA.This result implied that
the nanofibers of 3 could be a potential colorimetric acid sensor.
Therefore,we first tested such function in solution.The change in
the absorption behavior was monitored with UV-Vis spectroscopy
immediately after TFA was added to the chloroform solution of
compound 3.The absorbances at 422 and 402 nm decreased
gradually while new absorptions at 493 and 435 nm increased,and
eventually an absorption at 482 nm with a prominent shoulder at
ca.530 nm became dominant as the amount of TFA increased
(Fig.5(a)).However,it required a substantial excess of the acid to
saturate the spectral change.Note that there was no further
spectral change even after overnight standing,indicating that the
process is thermodynamic rather than kinetic.

如图4所示的那样,一旦添加TFA时,有从黄到红的明显颜色变化.这一结果告诉我们,化合物3的纳米纤维可以成为潜在的比色酸传感器.因此,我们首先在溶液中试验了这一功能.吸收性状用UV-vis(紫外-可见分光光度法)在TFA添加到化合物3的氯仿溶液中后立即进行检测.在422和402nm处的吸收度逐步降低,而在493和435nm处的新吸收度则增加,最终,在ca.530nm处带有突出的肩的482nm处的吸收就随着TFA量的增加而成为主导的(图5(a)).然而,要是光谱的变化饱和需要大大过量的酸.请注意,即使在过夜放置后也不会有进一步的光谱变化,这表明这一过程是热力学过程,而不是动力学过程.

如图4所示,加入TFA以后,颜色很明显地从黄色变成了红色。结果说明3号纤维有可能成为比色酸传感材料。因此,我们在溶液中测试了它的这个功能。3号化合物的氯仿溶液加入TFA以后 ,我们用UV-Vis分光光度计即时监测了它的吸光行为。 422nm和402nm处的吸光度逐渐减小,而在493nm和435nm处新的吸收峰的吸光度增加。随着TFA加入量的增加(如图5(a)),530nm峰肩上482nm处的吸收峰...

翻译不容易啊,后面有几句可能不是这么理解的,楼上用google翻的
