Anthracene-centered Derivatives: Design, Synthesis And Optical Property Study

Organic photoelectric functional materials increasingly highlight its position inmaterial science and have attracted extensive attention. Because of their unique propertiesand prospective applications in organic electroluminescent, organic solid laser,photoelectric sensors, and biological imaging. In this paper, we synthetized three series of9,10-divinylanthracene derivatives and discussed the relationship between their molecularstructure and photophysical properties.1. We synthetized a series of FLA-Cn with strong AIE effect、 Chain lengthdependencity and piezallochromy. Futher study indicates that, the fluorescent color ofFLA-C12can recover after grinded at room temperature. That is, the color turns toorange yellow to green through simple grind under365nm UV light, and turns to theoriginal green after10min at room temperature. This phenomenon is interesting and canbe used in many fields. By the X-ray and DSC we found that, the mechanism ofpiezallochromy is contributed to the transformation between crystalline and amorphous.2. We synthetized a series of PT-Cn which showed strong AIE effect, chain lengthdependencity and piezallochromy. To futher study, we found that the recovery proceduresof these compounds after been grinded are distinctive. That is, when the length of thealkyl chain is long, the compound is sencitive to the temperature; when the length of thealkyl chain is short, the compound is dependent to the temperature. The study of therecorver after ground is contributed to the exploration of piezallochromy.3. We synthetized a series of A2Cn, which have strong AIE effect andpiezallochromy. Besides, these compounds are special compared to the other series ofACZn in the chain length dependency and fluorescence quantum efficiency. Furthermore, fluorescence quantum efficiency becomes higher and the chain length dependencyturns weaker. This fully shows that, adjusting the key position of the end group canobviously change the fluorescent property of these compounds, it’s guidingly significantto synthetize parallel compounds.
