A series of boron-containing polycyclic aromatic hydrocarbons (PAHs) have been synthesized through the Ru-catalyzed cyclization of aryl ene-ynes. The benchtop-stable products show deep blue photoluminescence. Reversible electrochemical reduction is possible at moderate electrode potentials (about -2.0 V vs FcH/FcH(+)); some of the compounds also underwent reversible oxidation. The systematic expansion of the PAH scaffolds permitted the analysis of even subtle structure-property relationships.
通过钌催化的芳基烯炔环化反应合成了一系列含硼多环芳烃（PAHs）。这些在台面条件下稳定的产物呈现出深蓝色光致发光。在中等电极电位下（相对于FcH/FcH(+)约为 -2.0 V）可以进行可逆电化学还原；一些化合物还经历了可逆氧化。PAH骨架的系统扩展使得能够分析甚至是细微的结构 - 性质关系。
