Abstract

Four monocarborane anion-based compounds connected to a pyrene moiety were synthesized by combining two monocarborane anion scaffolds and two counter cations. The effects of the cage structure and the counter cation on the optical properties were investigated from UV‒vis absorption and photoluminescence (PL) measurements. The PL spectra in the solid state were unique for each compound, derived from the different shapes of the carborane cage and counter cation. These results suggest great potential for designing a monocarborane anion-based chromophore.

含有 [CB9H9]- 和 [CB11H11]- 簇单元的芘基发色团的合成、阳离子交换和光学特性

通过结合两种单碳硼烷阴离子支架和两种反阳离子，合成了四种连接芘分子的单碳硼烷阴离子基化合物。通过紫外-可见吸收和光致发光（PL）测量，研究了笼状结构和反阳离子对光学性质的影响。由于碳硼烷笼和阳离子的形状不同，每种化合物在固态下的光致发光光谱也各不相同。这些结果表明，设计基于单碳硼烷阴离子的发色团具有巨大的潜力。

期刊介绍： The Bulletin of the Chemical Society of Japan (BCSJ) is devoted to the publication of scientific research papers in the fields of Theoretical and Physical Chemistry, Analytical and Inorganic Chemistry, Organic and Biological Chemistry, and Applied and Materials Chemistry. BCSJ appears as a monthly journal online and in advance with three kinds of papers (Accounts, Articles, and Short Articles) describing original research. The purpose of BCSJ is to select and publish the most important papers with the broadest significance to the chemistry community in general. The Chemical Society of Japan hopes all visitors will notice the usefulness of our journal and the abundance of topics, and welcomes more submissions from scientists all over the world.
