摘要：

Organic crystals demonstrating efficient nonlinear optical (NLO) effects are highly promising candidates for the next-generation photonics. However, the assembly of NLO molecules with high dipoles in a non-centrosymmetric (NCS) manner for second-order NLO effects remains a formidable challenge. Here, we develop the self-assemblies of a fluorenone derivative, 2-([1,1′-biphenyl]-4-yl)-7-phenyl-fluoren (2-Bp-7-PFO), with an asymmetric configuration, which exhibits efficient second-harmonic generation (SHG) response, large polarization ratio, and outstanding optical stability. Driven by the synergetic intermolecular interactions, 2-Bp-7-PFO molecules arrange in an NCS way with two different morphologies. The exploration of NLO properties of fluorenone derivate with asymmetrical configuration could provide a new platform for the construction of organic NLO materials and devices in the future. © 2022 American Chemical Society.
