一种新型自聚集诱导发光材料的研究

Study on new aggregation-induced emission material

为了研究一种新型的聚集诱导发光材料(1-绕丹宁-芘),采用荧光光谱测量法和ORIGIN软件对样品进行了实验验证和理论分析,发现其具有一些新颖的光学性质。结果表明,在稀释溶液浓度时,样品的发射峰出现大幅蓝移;在升高温度时,样品出现了荧光增强现象。这些性质不同于常见的聚集诱导发光材料,与1-绕丹宁-芘在溶液中聚集时生成超分子结构有关。该研究在生物成像、医学领域、传感器、探测器及有机显示方面有一定的应用前景,对有机发光材料的研究有重要的意义。

By using fluorescence spectroscopy measurement method and ORIGIN software , new type of aggregation induced emission（AIE） material （1-rhodanine-pyrene） was studied by theoretical analysis and experimental verification and some new optical properties were discovered .The results show that when the concentration of solution dilutes , the emission peak of the sample shows a sharp blue shift .When the temperature increases , fluorescence strength of the sample enhances .These properties are different from common AIE materials , and it is related to super molecular structure induced from 1-rhodanine-pyrene aggregation in solution.The material has certain application prospect in biological imaging , medical field, sensors, photoelectric detection and organic display .The study has important significance in organic light-emitting materials .
