| Abstract |
Aggregation-induced emission (AIE) is an abnormal phenomenon observed in certain organic luminophores. A remarkable fluorescence attributed to freely rotating group occurred via the solid state, which was not seen in its solution state. This material can be applied to various devices such as bio-devices and fluorescence sensors. In this study, we have synthesized various hydrazone materials using hydrazone chemistry, and some of them observed the AIE properties. The molecular structure showing the AIE property was confirmed by the difference of substitution pattern (para-, meta-) and the number of substitution (mono-, bis-, and tris-). We also restrict rotational motions in the molecular structure by functionalizing amine group. Thus, it was confirmed that fluorescence was also observed in the solution phase. These AIE materials can be applied to various devices using many hydrazone functional groups. We made poly(ethylene oxide) films with these materials and confirmed that they could be applied as sensors. |
