The DSC/TG curves of BBPAB were determined, and the results showed that the thermal stability was good. The UV-Vis spectrum was measured, and there was a high linear transmittance in the visible range. The nonlinear absorption propertie of BBPAB was investigated under 190 fs (515-700nm) by Z-scan measurements. It was found that the BBPAB realized broadband reverse saturable absorption (RSA) under femtosecond excitation, and Third-order nonlinear absorption coefficient and fifth-order nonlinear absorption coefficient are obtained by fitting. Quantum chemical calculations indicated that There are strong transfer phenomena inside the molecule and larger polarizability of BBPAB. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1版权转让声明书附件1附件1附件2 -->
