摘要
本文制备了一种新型的含卟啉结构聚芳醚砜共价键修饰的多壁碳纳米管杂化材料。由于体系中作为电子给体的卟啉结构与电子受体碳纳米管之间存在高效的电子和能量转移效应,导致卟啉的荧光大部分被淬灭,荧光寿命显著降低。Z扫描测试表明杂化材料在532 nm和1064 nm的纳秒激光脉冲下均表现出增强的非线性光学性质,这是源于非线性吸收、散射和光致电子/能量转移等不同机制的协同作用效果[1]。此外,杂化材料的分散性得到改善,可均匀地分散在聚合物基质中制备薄膜光限幅材料。
A novel multi-walled carbon nanotubes(MWNT) hybrid was synthesized by covalently attaching a porphyrinated poly(arylene ether sulfone) onto the surface of nanotubes. Considerable fluorescence quenching and shortened fluorescence lifetime were observed in the MWNT hybrid due to an efficient electron/energy transfer behavior. Z-scan measurements demonstrated the improved broadband nonlinear optical performance of the MWNT hybrid at both 532 and 1064 nm in nanoseconds, which is attributed to the accumulation effect of nonlinear absorption and scattering, and a remarkable photo-induced electron/energy transfer process from porphyrin moieties to MWNTs. Meanwhile, the MWNT hybrid was found to exhibit good solubility and could be homogeneously dispersed in polymer matrix, further fabricated into uniform film with high transparency and fast optical limiting response under femtosecond laser pulses.
