Tetrasubstituted Imidazole Derivatives and Their Imidazolium: Photophysical Properties in Aggregate State and Application in Adenosine Detection

Anion-π+ interaction as an important type of non-covalent interaction has great potential in the construction of aggregation-induced emission (AIE) molecules. In this work, tetraphenylimidazole (PI) and diphenylphenanthroimidazole (PPI) were used...
