non-linear optical (NLO) properties. For comparison, calculated UV–Vis absorptions and frontier molecular orbitals (FMO) analysis were computed using TD-DFT/M06/6–311G(d,p) approaches. The NBO analysis concludes that prolonged hyperconjugation and strong ICT exist in all the entitled compounds, which stabilizes the systems and also offers key evidence of charge transfer/NLO properties.
