A carbazole derivative (3-(2,2-dicyanovinyl)-9-hexylcarbazole, abbreviated as L) has been designed, synthesized and used to prepare a novel organic–inorganic nanohybrid consisting of silver nanocrystals (Ag NCs) uniformly dispersed on the surface of L nanoribbons. Detailed characterizations have been performed. The results reveal that L couples with Ag NCs through a π-conjugated unit, which results in a significant red-shift of the fluorescence (FL), an obvious increase of FL lifetime and enhanced Raman scattering.
我们设计、合成了一种咔唑衍生物(3-(2,2-二氰基乙烯基)-9-己基咔唑,简称 L),并用它制备了一种新型有机-无机纳米杂化物,该杂化物由均匀分散在 L 纳米带表面的银纳米晶体(Ag NCs)组成。对其进行了详细的表征。结果表明,L 通过 π 共轭单元与 Ag NCs 发生耦合,从而导致荧光(FL)显著红移、FL 寿命明显增加以及拉曼散射增强。
