Abstract

Compared with traditional fluorescent materials exhibiting aggregation-caused quenching (ACQ), small organic molecules with aggregation-induced emission (AIE) characteristics demonstrate significant advantages in biomedical detection due to their special structures and optical properties. However, the single functionality of fluorescent materials can no longer meet the demands of multiple applications. The development of multifunctional materials is expected to become a major research focus. In this paper, a D-π-A organic small molecule (E)-9-Butyl-3-(2-(pyridin-4-yl)vinyl)-9H-carbazole (PC) was designed and synthesized through the Wittig reaction. In the molecule, modified carbazole group served as the electron donor (D) and pyridine as the electron acceptor (A). The results of X-ray single crystal diffraction, spectral measurements and theoretical calculations demonstrate that PC exhibits excellent aggregation-induced emission properties, attributed to its J-aggregation stacking model. Furthermore, PC was found to exhibit acid-stimulated fluorescence response properties, which expands its potential applications in encrypted information transmission, fluorescent ink, and cell imaging, thereby injecting new vitality into the field of multifunctional materials.

聚集体诱导发射有机小分子多功能材料的荧光特性及多方面应用

与具有聚集致猝灭（ACQ）特性的传统荧光材料相比，具有聚集致发射（AIE）特性的有机小分子由于其特殊的结构和光学性质，在生物医学检测中具有显著的优势。然而，单一功能的荧光材料已经不能满足多种应用的需求。多功能材料的开发有望成为一个重要的研究热点。本文通过Wittig反应设计合成了D-π- a有机小分子(E)-9-丁基-3-（2-（吡啶-4-基）乙烯基）- 9h -咔唑（PC）。在分子中，修饰的咔唑基团作为电子给体(D)，吡啶作为电子受体(A)。x射线单晶衍射、光谱测量和理论计算结果表明，PC具有良好的聚集诱导发射特性，这归因于其j聚集堆积模型。此外，研究发现PC具有酸刺激荧光响应特性，拓展了其在加密信息传输、荧光油墨、细胞成像等方面的应用潜力，为多功能材料领域注入了新的活力。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
