tetra‐aminated pyrenes. All bisazoliums show fluorescence properties, with emissions in the range of 370–420 nm, and quantum yields ranging from 0.29 to 0.41. The PBIs were used as bis‐NHC precursors in the preparation of a series of dirhodium and diiridium complexes, which have been fully characterized. The electrochemical studies on selected dimetallic complexes reveal that the electronic communication between
从4,5,9,10-四溴-2-2,7-二叔丁基starting开始获得一系列of基双偶氮盐。bis-双偶氮鎓(PBI)的合成程序显示出出乎意料的行为,这是由于最终产物中三烷氧基甲酸酯的烷基(烷基= Me,Et,n- Pr和n- Bu)的存在,而不是预期的牛逼卜ŧ起始四胺基from的戊基。所有的双偶氮鎓均显示荧光性质,发射范围为370–420 nm,量子产率为0.29至0.41。PBI被用作双-NHC前体,用于制备一系列已充分表征的二ho和二铱配合物。对选定的双金属配合物的电化学研究表明,金属之间通过多芳族连接基的电子通讯可忽略不计。
