A fluorescent dye, the pyridomethene-BF(2) complex, has been synthesized. Although pyridomethenes did not exhibit fluorescence, pyridomethene-BF(2) complexes exhibited fluorescence both in solution and in the solid state. The trifluoromethyl-substituted BF(2) complex formed a J-aggregate and showed the highest fluorescence quantum yield in the solid state among all pyridomethene-BF(2) complexes.
一种荧光染料，即吡咯并[B,F]噻唑-BF2配合物已被合成。尽管吡咯并[B,F]噻唑本身不发荧光，但吡咯并[B,F]噻唑-BF2配合物在溶液和固态中均表现出荧光。三氟甲基取代的 BF2配合物形成 J-聚集体，在所有吡咯并[B,F]噻唑-BF2配合物中，其在固态下具有最高的荧光量子产率。
