吸收红色和蓝色的硼二吡罗甲烷染料，携带相反的电子电荷，在溶液中结合形成1:2的络合物，稳定常数约为10(17)M（-2）。配合物可以通过添加大量过量的四正丁基铵阳离子来分解。相同的配合物在从室温加热到150°C以上时显示出液晶性质，这是通过各种实验技术表征的。从红色到蓝色染料的高效电子能量转移发生在初始络合物和随后的亚形态状态。
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 techniques. Highly efficient electronic energy transfer from the red to the blue dye occurs in both the initial complex and the subsequent mesomorphic state.
