Abstract

A synthetic method for 2-thiomorpholinopyridine-3,4-dicarbonitrile derivatives was developed based on 2-chloropyridine-3,4-dicarbonitriles and thiomorpholine. The obtained compounds exhibit a rare type of dual-state emission (DSE), featuring fluorescence both in solution and in the solid state. The fluorescence maxima in benzene solution depend on the nature of the substituents and range from 470 to 508 nm, while in the solid state, they vary from 473 to 534 nm.

吡啶二腈噻吩啉衍生物的合成及双态发射

以2-氯吡啶-3,4-二碳腈和噻吩啉为原料，合成了2-硫代氨基吡啶-3,4-二碳腈衍生物。所获得的化合物表现出一种罕见的双态发射（DSE），在溶液和固体中都具有荧光。在苯溶液中，荧光最大值取决于取代基的性质，范围为470 ~ 508 nm，而在固态中，荧光最大值为473 ~ 534 nm。

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.
