A novel material showing aggregation induced emission (AIE) is developed by reprecipitation method using 9‑Anthraldehyde (9-AC), where Sodium dodecyl sulfate (SDS) was used as morphology directing agent. 1-dimension rod and 2-dimension elongated hexagon shaped morphology of 9-AC aggregates have been synthesized. Morphology of the materials was characterized using optical microscopy. Photophysical properties of the hydrosol were studied using UV–Vis, steady state and time resolved fluorescence emission techniques. Computation of second order Fukui parameter as local reactivity descriptor on each atomic center of the titled compound also substantiate that the neighboring 9-AC molecules are arranged in trans conformation in its aggregated structures and this is in conformity with the crystal structure of 9-AC. The ‘turn off’ fluorescence property of aggregated 9-AC has been utilized for selective detection of picric acid and the fluorescence quenching has been explained due to ground state complexation between 9-AC and picric acid. The observed detection limit of picric acid was found as low as 8.07 μM.

通过使用9‑乙醛（9-AC）的再沉淀方法开发了一种显示聚集诱导发射（AIE）的新型材料，其中十二烷基硫酸钠（SDS）被用作形态学指导剂。合成了9-AC聚集体的1维杆和2维细长六角形形态。使用光学显微镜表征材料的形态。使用UV-Vis，稳态和时间分辨荧光发射技术研究了水溶胶的光物理性质。在标题化合物的每个原子中心上作为局部反应性描述符的二阶Fukui参数的计算也证实了相邻的9-AC分子以反式构象排列在其聚集结构中，这与9-AC的晶体结构相符。聚集的9-AC的“关闭”荧光特性已被用于选择性检测苦味酸，并且由于9-AC和苦味酸之间的基态络合，已经解释了荧光猝灭。发现观察到的苦味酸的检出限低至8.07μM。
