Abstract

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.
