chromospheres, with ferrocene as the electron donor and pyridinium as the electron acceptor, were synthesized. The nonlinear optical absorption (NOA) properties in the solution state were investigated by the Z-scan technique. Both compounds exhibited reverse saturable absorption (RSA) and optical limiting effect under nanosecond pulse irradiation.
合成了两个电子供体-π-受体(D-π-A)色球,其中
二茂铁作为电子供体,
吡啶鎓作为电子受体。通过Z扫描技术研究了溶液状态下的非线性光学吸收(NOA)特性。两种化合物在纳秒脉冲辐射下均表现出反向饱和吸收(RSA)和光学限制效应。
