【摘要】：熒光成像技術作為一種無創(chuàng)傷的技術,已被廣泛用于跟蹤和了解生物體內或體外復雜的環(huán)境,這在現(xiàn)代生命科學研究中都具有重要意義。與其他成像方式相比,熒光成像具有很高的時空分辨率。熒光成像的核心是熒光材料。因此,各種各樣具有高熒光強度,良好光穩(wěn)定性,高靈敏度,高信噪比,毒性低等特點的熒光材料已被設計和合成。本論文主要研究三種不同的共軛有機熒光材料在生物方面的應用,包括近紅外熒光材料、固態(tài)熒光材料和熱激活延遲熒光材料。具體主要包括下面三方面:(1)通過幾種比較常見的合成方法制備了一種具有給體-受體-給體結構的材料TAT-DPP-TAT。一方面,由于常見的近紅外的有機半導體熒光材料具有良好的光熱效應,所以將材料TAT-DPP-TAT用于光熱治療;另一方面,由于中心體吡咯并吡咯二酮在光動力治療方面具有良好的作用,所以進行了光動力治療方面的測試,最終實現(xiàn)了材料的多應用。(2)本章通過對傳統(tǒng)氟硼二吡咯材料結構的改變,設計合成了一種在固態(tài)狀態(tài)下依然保持強熒光特性的材料。通過一系列的表征,研究其結構與性能的關系。(3)通過Cadogan關環(huán)設計合成了幾種咔唑衍生物,然后通過一步法反應合成了幾種具有給體-受體結構的熱激活延遲熒光材料。通過對其性能的研究,主要包括其性能與結構之間的關系,并在有機電致發(fā)光器件中得到應用。
[Abstract]:As a non-invasive technique, fluorescence imaging technology has been widely used to track and understand the complex environment in vivo or in vitro, which is of great significance in modern life science research. Compared with other imaging methods, fluorescence imaging has high spatial and temporal resolution. The core of fluorescence imaging is fluorescent material. Therefore, various fluorescent materials with high fluorescence intensity, good light stability, high sensitivity, high signal-to-noise ratio and low toxicity have been designed and synthesized. In this paper, three kinds of conjugated organic fluorescent materials are studied in biological applications, including near infrared fluorescent materials, solid state fluorescent materials and thermal activated delayed fluorescence materials. A novel material with donor-receptor-donor structure, TAT-DPP-TAT, was prepared by several common synthetic methods. On the one hand, the common near infrared organic semiconductor fluorescent materials have good photothermal effect, so the material TAT-DPP-TAT is used for photothermal therapy; on the other hand, Since pyrrolidine pyrrolidone has a good role in photodynamic therapy, it has been tested in photodynamic therapy, and finally the multi-application of materials has been realized.) in this chapter, the structure of traditional fluoropyrrole dipyrrole materials has been changed by means of changing the structure of traditional fluoropyrrole dipyrrole materials. A material with strong fluorescence properties in solid state was designed and synthesized. Several carbazole derivatives were synthesized by Cadogan closed loop design, and then some heat-activated delayed fluorescence materials with donor-receptor structure were synthesized by one-step reaction. Through the study of its performance, including the relationship between its performance and structure, it has been applied in organic electroluminescent devices.
