dimerization by oxidative coupling with phenyliodine(III)-bis(trifluoroacetate) (PIFA). This dimerization was achieved for BODIPYs substituted in the 3,5-positions with either methyl or thienyl groups. The position and the type of the linkage in the resulting dimers depended on the nature of the substituent. The 3,5-dimethyl-BODIPY dyes were linked either via direct 1,1′-pyrrole–pyrrole coupling or via a 1,3′-methylene
我们报告了具有未取代的1,7,8位的BODIPYs的合成及其通过与苯基碘(III)-双(三氟乙酸)(PIFA)的氧化偶联而二聚化。对于在3,5-位被甲基或噻吩基取代的BODIPY,可以实现这种二聚化。所得二聚体中键的位置和类型取决于取代基的性质。3,5-二甲基-BODIPY染料通过直接的1,1'-吡咯-吡咯偶联或通过1,3'-亚甲基桥连接。3,5-二噻吩基-BODIPY染料以优异的产率提供了仅通过α-噻吩基位置连接的独特化合物。所有染料在8位均不反应。对单体和二聚体的电化学和光谱测量提供了二聚体的两半之间相互作用的证据。因此,
