Light induced nonlinear optical switch in boronated chromophores: A theoretical search towards high contrast switches in the azobenzene series

Searching NLO switches in azobenzene boronated derivatives. Large DFT static computed hyperpolarizabilities, for E-2 (52.8 × 10−30 cm5 esu−1) and for Z-2 (6.19 × 10−30 cm5 esu−1) with a switching contrast (βon/βoff = 8.53).
