Abstract
AbstractThe carbazole styryl based fluorescent molecular rotors (FMRs) with different chemical functionalities at C=C bond were synthesized and characterized spectroscopically. These compounds exhibits bright solid state fluorescent and also exhibits aggregation induced emission (AIE) and fluorescent response towards viscosity. Apart from traditional p‐(dialkylamino)‐benzylidene malonitriles motifs, we have used carbazole styryl dyes as viscosity sensors. In this study we have discussed about the effect of chemical functionalities/ substituents on the fluorescent properties, aggregation induced emission (AIE) and viscosity sensitivity. These compounds can find potential applications in biomedical field as fluorescent molecular rotors for viscosity determination.
