coupling, and O-chelation. The absorption maxima of the BODIPYs ranged from the visible to near-infrared region and the compounds showed good solubility in organic solvents. The solubility of the bicycloBODIPY with 2-naphthyl groups at the α-position of the pyrrole units was particularly high. Heating converted distyrylBODIPY with bicyclo[2.2.2]octene to benzoBODIPY with absorption (748.5 nm) and fluorescence
通过结合Knoevenagel缩合,Suzuki偶联和O-螯合,从双环
吡咯合成了与双环稠合的新型扩展BODIPY 。BODIPYs的最大吸收范围是从可见光到近红外区域,并且这些化合物在有机溶剂中显示出良好的溶解性。在
吡咯单元的α-位置具有2-
萘基的双环BODIPY的溶解度特别高。将具有双环[2.2.2]
辛烯的转化的
苯乙烯基BODIPY加热至在近红外区具有吸收(748.5 nm)和荧光(775.0 nm)的苯并BODIPY。
