The commercially available 3,4,9,10‐perylenetetracarboxylic diimide (PTCDI) acted as a heterogeneous catalyst to catalyze aerobic oxidative synthesis of benzimidazoles, benzothiazoles, and quinoxalines from o‐substituted aniline derivatives and primary amines in high yields with oxygen as the terminal oxidant. The gram scale reaction and reusability (up to six cycles) of the PTCDI catalyst were also successful and would greatly benefit industrial applications.

Aluminum (Al) is widely used in food industry, but excessive absorption of Al3+ causes many serious health problems. Therefore, it is of great significance to determine the specificity of Al3+. In this study, we designed and synthesized a water‐soluble perylene diimide derivative (PDI‐Phe) for monitoring Al3+ rapidly and visually. Through absorption and emission spectroscopy techniques, we systematically explored the properties and mechanism of the sensor to Al3+. The limit of detection (LOD) of Al3+ was as low as 6.54 nM. And with the existence of Al3+, electrostatic interaction and intermolecular π‐π stacking promoted the aggregation and fluorescence quenching of PDI‐Phe. Even in the presence of other analytes, PDI‐Phe still had excellent selectivity and sensitivity for Al3+ detection. Besides, it also had the characteristics of low cost, good water solubility, excellent chemical and optical stability, and easy synthesis. Finally, this method can be further applied to tap water samples.
