Synthesis, cation exchange, and optical properties of pyrene-based chromophores containing [CB9H9]− and [CB11H11]− cluster units
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.
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.
