Abstract
AbstractThis review is about anthraquinone dyes. One of the advantages of organic NLOphores materials is the variety of chromophores explored for a wide range of potential applications in optoelectronics and biology. The second and third harmonic generations, as well as hyper‐Rayleigh scattering (HRS), the Z‐scan technique, degenerate four‐wave mixing (DFWM), and density functional theory (DFT), are all covered in this review. The most active sites for establishing enhanced NLO properties were found to be positions 2 and 6 of the anthraquinone core. The structural characteristics of dyes are used to divide them into subcategories. In each section, structures with a higher NLO response are highlighted. Researchers will benefit from this review when designing and synthesizing NLOphores.
