Abstract

A polyyne dendrimer (PD) was synthesized in four-steps and characterized by ¹H NMR, ¹³C NMR, MS, FT-IR, etc. Subsequently, ultraviolet visible (UV-Vis) absorption spectra and fluorescence spectra were further investigated in a series of solvents, in which obvious aggregation-induced emission (AIE) were observed. In addition, the electrochemiluminescence (ECL)properties in solid state were also investigated. Interestingly, the π-extended PD with slight distorted configuration possessed intense and stable cathodic ECL emission, which indicatedthat it has potential application in the future construction of high-performance ECL emitters.

聚炔树枝状聚合物的合成与光学特性

通过四个步骤合成了一种聚炔树枝状聚合物（PD），并利用 1H NMR、13C NMR、MS、FT-IR 等对其进行了表征。随后，在一系列溶剂中进一步研究了紫外可见（UV-Vis）吸收光谱和荧光光谱，观察到了明显的聚集诱导发射（AIE）。此外，还研究了固态下的电化学发光（ECL）特性。有趣的是，具有轻微扭曲构型的π-扩展 PD 具有强烈而稳定的阴极 ECL 发射，这表明它在未来构建高性能 ECL 发射器中具有潜在的应用价值。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
