Triphenylvinyl (TPV) substituted bisthiazole 4 and tetraphenylethylene (TPE) substituted triphenylamine functionalized oxazole 5 were designed and synthesized by the Pd‐catalyzed Suzuki cross‐coupling reaction. The TPV 4 shows Aggregation‐induced emission (AIE) behavior and TPE 5 shows aggregation‐caused quenching (ACQ) in THF/water mixture due to π‐π stacking. The TGA analysis reveals that the TPE 5 show better thermal stability as compared to TPV 4 .
