mol/L水溶液的紫外-可见吸收强度减弱
且变化灵敏。当该溶液的pH从10.75减小到9.66时
荧光强度急剧降低; 当pH从9.66继续减小到5.12时
荧光强度减弱相对缓慢; 当pH值减小到5.12以下时
荧光强度迅速降低直至猝灭。pH的改变对发光团-堆积产生影响进而导致其荧光发射光谱和可见吸收光谱发生改变。该化合物是一个很好的水溶性pH荧光探针。

10-tetracarboxylic diimide(PTCDA)was synthesized and characterized. The UV-vis absorbance of PTCDA(10
-5
mol/L) solution is sensitive to pH value over a wide range from 10.75 to 3.97
and a gradual decrease with absorption intensity was observed as pH ranging from 10.75 to 4.73.A rapid decline in fluorescence intensity was found with pH varing from 10.75 to 9.66
while a trady reduction in fluorescence intensity was found upon a fall in pH from 9.66 to 5.12. The fluorescence of PTCDA was quenched when the pH was inferior to 5.12. The change of fluorescence spectrum and absorption spectrum can be attributed to the - stacking produced by pH value.This indicates PTCDA can be used as a pH probe in water solution.
