N2 - Organic dyes with conformational sensitivity can be used to probe weak interactions at the molecular level. Here, three molecules based on tetraphenyl-1,3-butadienes (TPBs) were synthesized and studied with respect to their synthesis, structural characterization and potential application. All TPBs showed aggregation-induced emission (AIE) characteristics and sensitive conformational properties, in which the emission wavelengths could be changed in different states. The TPBs single crystals revealed that the phenyl groups at the 4-position of the 1,3-butadienes contributed to their conformational sensitivity. Furthermore, the potential application for monitoring the interactions among polyelectrolyte complexes and metal ions was explored, and the results showed that TPBs could be used for sensitively probing some weak interactions by changing the emission wavelengths due to their conformation-sensitive properties. TPBs may become a new star in AIE research fields.
