Abstract
本发明提供了一类710nm激发的高亮度荧光染料及其合成方法,该荧光染料为通过在苝酰亚胺9,10‑位引入乙二胺类似物设计合成的一系列高亮度的710nm荧光染料,其结构式如(1)所示,环己二胺结构的平面性使供电性进一步增加,乙醇中吸收波长达到712nm,荧光发射波长达到750nm。由于乙二胺结构与苝酰亚胺之间形成的强烈环张力导致分子内扭转受到严格的限制,这使得在近红外区分子仍然能够保持0.40以上的量子产率。此外本系列染料荧光半峰宽只有40nm,能够广泛应用于活细胞、活体等实时多色荧光成像。
Description
技术领域
本发明属于近红外荧光染料领域,具体涉及一类710nm激发的高亮度荧光染料及其合成方法。
背景技术
由于具有深的组织穿透性、低背景荧光干扰、小的生物样本光损伤等特点,近红外荧光生物成像技术引起了研究工作者越来越多的关注。在众多荧光信使中,有机小分子荧光染料以其生物相容性好、结构易改造等优势也被广泛应用于近红外荧光成像。但是,结构简小的有机小分子荧光染料荧光发射波长通常在400-700nm,吸收与发射波长达到700nm以上的单个共轭的有机小分子体极为匮乏,这也使得近红外区域的多色成像变得极为困难。
目前,被广泛应用于近红外荧光成像的有机小分子多为花菁染料染料及其类似物。Alexa系列染料中Alexa700为633-647nm激发,723nml发射;Alexa750 为Cy7类染料,激发与发射分别为753nm/782nm。可见在Alexa系列染料中 700-750nm激发与发射的染料存在一定空白,这也限制了多色的近红外荧光成像。如何通过分子的简单改造使荧光染料红移至近红外区的同时保持荧光的高亮度是亟待解决的问题,同时又极富挑战性。
发明内容
本发明的目的是提供一类710nm激发的高亮度荧光染料及其合成方法,该系列染料荧光量子产率在不同溶剂中达到0.40以上。
本发明提供一类710nm激发的高亮度荧光染料,以苝酰亚胺为荧光团,通过9,10-位乙二胺类似结构的引入使苝酰亚胺的荧光稳定性、亮度得到大幅度提升,乙醇中荧光波长红移750nm。
一类710nm激发的高亮度荧光染料,该系列荧光染料具有如下结构 :
其中R1为C1-C4烷基、(CH2CH2O)nH、(CH2)nCOOMe,n为1,2,3,4等整数。
一类710nm激发的高亮度荧光染料的合成方法,此系列荧光染料合成路线,如下:
具体合成步骤如下:
(1)中间体N-烷基-9,10-二溴-1,6,7,12-四氯苝酰亚胺的合成:
将9,10-二溴-1,6,7,12-四氯苝酰亚胺与醇伯胺或脂肪伯胺溶于N-甲基吡咯烷酮与冰醋酸混合液中;将反应液加热至100-140℃,搅拌1-10h;将反应液泠却至室温后倒入冰水中抽滤得黑色固体,真空干燥,硅胶柱(200-300目二氧化硅) 分离,以二氯甲烷:石油醚(体积比1:0.25~6)为洗脱剂,减压除去溶剂得深红色固体N-烷基-9,10-二溴-1,6,7,12-四氯苝酰亚胺。
其中,9,10-二溴-1,6,7,12-四氯苝酰亚胺与醇伯胺或脂肪伯胺的质量比为 1-5:1;9,10-二溴-1,6,7,12-四氯苝酰亚胺的质量与N-甲基吡咯烷酮与醋酸混合液的体积比为1:20-60(g:mL);N-甲基吡咯烷酮与冰醋酸的体积比为3:1-3。
(2)探针N-烷基-9,10-环己二胺基-1,6,7,12-四氯苝酰亚胺的合成:
将N-烷基-9,10-二溴-1,6,7,12-四氯苝酰亚胺,溶于乙二醇甲醚中,并向其中加入氮杂环丁烷;而后将反应液缓慢升温至90-130℃,并在氮气保护下反应 10-24h;减压除去溶剂,硅胶柱(200-300目二氧化硅)分离,以二氯甲烷:石油醚(体积比1:0~1)为洗脱剂,减压除去溶剂,得蓝色固体探针N-烷基-9,10- 二-氮杂环丁基-1,6,7,12-四氯苝酰亚胺。
其中,N-烷基-9,10-二溴-1,6,7,12-四氯苝酰亚胺与反式环己二胺的质量比为1-4:1-6;反式环己二胺与乙二醇甲醚的质量与体积比为5-60:1(mg:mL)。
