摘要

采用希夫碱与醛醇缩合反应合成了3种具有不同取代基的新型三乙苯衍生物（B1、B2和B3）。B1、B2和B3表现出反向饱和吸收。由于能隙小，B1在三种衍生物中具有最低的初始光学限制阈值。而B3具有较大的π共轭结构和吸电子羰基，在较高的激光能量下表现出较强的反向饱和吸收。合成的三乙基苯衍生物在激光防护领域具有潜在的应用前景。

Synthesis and nonlinear optical properties of triethylbenzene derivatives with different substituents

Three novel triethylbenzene derivatives (B1, B2 and B3) with different substituents have been synthesized by Schiff-base and aldol condensation reaction. B1, B2 and B3 exhibit reverse saturable absorption. B1 has the lowest initial optical limiting threshold among the three derivatives because of its low energy gap. However, B3, which has a larger π-conjugate structure and electron-withdrawing carbonyl groups, exhibits strong reverse saturable absorption at higher laser energy. The synthesized triethylbenzene derivatives may be potential candidates for applications in the field of laser protection.
