Aggregation-induced emission (AIE) is a phenomenon wherecertainmolecules or materials become highly luminescent when they aggregateor come together in a condensed state, such as a solid or a solution.Moreover, new molecules which show AIE properties are designed andsynthesized for various applications like imaging, sensing, and optoelectronics.2,3,5,6-Tetraphenylpyrazine (TPP) is one of the well-established examplesof AIE. Herein, 2,3,5,6-tetraphenyl-1,4-dioxin (TPD) and 2,3,4,5-tetraphenyl-4H-pyran-4-one (TPPO), which are old molecules with TPP similarity,were studied, and new insights in terms of structure and aggregation-causedquenching (ACQ)/AIE properties were gained by means of theoreticalcalculations. Those calculations performed on TPD and TPPO aimed toprovide a better understanding of their molecular structures and howthey affect their luminescence properties. This information couldbe used to design new materials with improved AIE properties or tomodify existing materials to overcome ACQ.
