Description

一种具有红色聚集诱导发光特性的卟啉衍生物及其制备方法 和应用
技术领域
本发明属于发光材料技术领域，具体涉及一种具有红色聚集诱导发光特性的卟啉衍生物及其制备方法和应用。
背景技术
卟啉类化合物广泛存在于自然界的生命体内，如叶绿素、血红素和细胞色素等都是卟啉衍生物，在生命活动中发挥着重要作用。卟啉是一类具有18π电子共轭的刚性平面大分子杂环化合物，在可见光范围内具有强的吸收和发射性质。卟啉及其衍生物已广泛应用于金属离子分析检测、生物成像、液晶材料、有机电致发光材料和染料敏化太阳能电池等领域。
但是卟啉类化合物在较高浓度或固态下，由于刚性平面共轭结构，分子间存在强烈的π-π相互作用而紧密堆积，导致荧光猝灭；卟啉类化合物具有独特的光电性质，采用卟啉掺杂的有机电致发光材料已成为研究热点；由于卟啉分子间的聚集导致荧光猝灭，使得单一卟啉作为发光二极管很难实现，因此在发光器件方面的应用受到了限制。为解决这一问题，开发卟啉聚集态发光很有必要。聚集诱导发光(Aggregation Induced Emission,AIE)现象由唐本忠课题组2001年首次发现，噻咯和四苯基乙烯是典型的AIE分子，这类化合物与卟啉发光现象完全相反，在聚集态和固体时能够发射很强的荧光，为解决有机发光材料聚集荧光猝灭问题提供了新策略。
发明内容
本发明的第一个目的是为了解决上述问题，提供了一种具有红色聚集诱导发光特性的卟啉衍生物。
本发明的第二个目的是提供上述卟啉衍生物的制备方法。
本发明的第三个目的是提供上述卟啉衍生物的用途。
本发明的目的通过以下技术方案来具体实现：
一种具有红色聚集诱导发光特性的卟啉衍生物，结构式如下所示：
Figure BDA0002272929530000021
上述具有红色聚集诱导发光特性的卟啉衍生物的制备方法，具体包括如下步骤：
(1)制备5-(4-氨基苯基)-10,15,20-三苯基卟啉
首先采用Adler法合成四苯基卟啉，然后将四苯基卟啉溶于三氟乙酸，在低温条件下加入亚硝酸盐进行硝化反应，反应结束后，纯化分离得5-(4-硝基苯基)-10,15,20-三苯基卟啉，再在浓盐酸溶液中加入无机盐还原剂进行还原，加热回流，纯化分离得5-(4-氨基苯基)-10,15,20-三苯基卟啉；
(2)制备[1-(4-甲醛基联苯基)-1,2,2-三苯基]乙烯
将1-(4-溴苯基)-1,2,2-三苯基乙烯和4-甲酰基苯硼酸通过Suzuki偶联反应，合成[1-(4-甲醛基联苯基)-1,2,2-三苯基]乙烯；
(3)制备聚集诱导发光卟啉衍生物
将5-(4-氨基苯基)-10,15,20-三苯基卟啉和[1-(4-甲醛基联苯基)-1,2,2-三苯基]乙烯通过Schiff反应，得到四苯基乙烯基团修饰的卟啉衍生物。
进一步的，步骤(1)中，所述低温条件为-15℃，所述亚硝酸盐为亚硝酸钠，硝化反应的时间为30min；所述无机盐还原剂为SnCl2·2H2O；加热回流在80℃下回流12h。
进一步的，步骤(3)中，5-(4-氨基苯基)-10,15,20-三苯基卟啉和[1-(4-甲醛基联苯基)-1,2,2-三苯基]乙烯的摩尔比为1:2。
上述卟啉衍生物在有机电致发光、生物成像材料中的应用。
本发明通过四苯基乙烯分子共价连接卟啉，能够实现卟啉化合物在聚集态和固态下发射红色荧光，使卟啉从聚集荧光猝灭转变为AIE性质。该材料可广泛应用于有机电致发光等领域。
本发明具有以下有益效果：
本发明提供的具有红色聚集诱导发光特性的卟啉衍生物，通过四苯基乙烯基团修饰卟啉分子，由于四苯基乙烯“螺旋桨”状非平面结构的引入，在空间结构上极大的降低卟啉分子间的π-π堆积作用，使卟啉从聚集荧光淬灭转变为聚集诱导发光；该卟啉衍生物能够在聚集态和固体时发射强烈的红色荧光，能够在有机电致发光器件及近红外生物成像领域取得很好的应用。
