Abstract
A polyyne propeller was synthesized and the structure was characterized via 1H, 13C NMR and FT-IR, etc. Subsequently, its photophysical properties in a series of solvents were investigated by steady-state spectroscopy and transient spectroscopy. Intriguingly, the polyyne in ethyl acetate solution exhibited intense electron absorptions, fluorescence emission. In addition, electrochemiluminescence (ECL) properties of the polyyne was further studied and it displayed strong and stable cathodic ECL emission. Considering its extraordinary ECL performance, the polyyne was used as an ECL material to construct a sensor for dopamine assay, which exhibited wide linearity (10 pM to 1 mM) with a low detection limit of 3.72 pM. This work offered new insight for preparing high-performance ECL material and will be beneficial for developing efficient sensors for biological application.
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.
