The changeable molecular dynamics of flexible polar cations in the variable confined space between inorganic chains brings about a new type of two-step nonlinear optical (NLO) switch with genuine "off-on-off" second harmonic generation (SHG) conversion between one NLO-active state and two NLO-inactive states.
柔性极性阳离子在无机链之间的可变受限空间中多变的分子动力学,带来了一种新型的两步非线性光学(NLO)开关,在一个 NLO 活性态和两个 NLO 非活性态之间具有真正的“关-开-关”二次谐波产生(SHG)转换。
