Red- and blue-absorbing boron dipyrromethene dyes, bearing opposite electronic charges, associate in solution to form a 1:2 complex having a stability constant of ca. 10(17) M(-2). The complex can be dismantled by addition of a large excess of tetra-N-butylammonium cations. The same complex displays liquid crystalline properties on heating from rt to above 150 °C, as characterized by various experimental
吸收红色和蓝色的硼二吡咯亚甲基染料,带有相反的电荷,在溶液中结合形成 1:2 的复合物,其稳定性常数约为 10(17) M(-2)。可以通过添加大量过量的四正丁基铵阳离子来分解络合物。相同的复合物在从室温加热到 150°C 以上时显示出液晶特性,正如各种实验技术所表征的那样。从红色染料到蓝色染料的高效电子能量转移发生在初始复合物和随后的介晶状态。
