D‐Carbazole‐A Compounds: Modulation of Second‐Order Nonlinear Optical Properties by Substituent Types and Positional Isomerism
Three‐dimensional materials exhibiting through‐space charge transfer (TSCT) have garnered extensive research interest in the field of nonlinear optics (NLO). In this work, density functional theory (DFT) was employed to systematically investigate a series of donor (D)‐carbazole‐acceptor (A) type compounds ( 1–6 )...
