We have synthesized a new family of directly-fused bisBODIPY BBP 1 through a key FeCl3-mediated intramolecular oxidative cyclodehydrogenation reaction and its derivatives 2 and 3 from the Knoevenagel reaction. These dyes display effective expansion of π-conjugation over the two BODIPYs due to their locked coplanar conformation, showing intriguing electrochemical and spectroscopic properties, such as intensive absorption/emission bands ranging from 676 to 877 nm and high photostability.
我们通过关键的FeCl₃介导的分子内氧化环脱氢反应合成了一个新的直接稠合双硼二吡咯BBP 1家族，并通过克诺文纳格尔反应合成了其衍生物2和3。由于其锁定的共平面构象，这些染料在两个硼二吡咯上显示出有效的π共轭扩展，展现出有趣的电化学和光谱性质，如676至877 nm范围内的强吸收/发射带以及高光稳定性。
