In this study, a large-aperture hole-patterned liquid crystal (LHLC) lens was prepared from a mixture of nematic liquid crystal (NLC, E7) and organic material (N-benzyl-2-methyl-4-nitroaniline, BNA). The electro-optic properties of doped and undoped samples were measured, compared, and analyzed. The doped sample exhibited a response time that was ∼6 times faster than that of the undoped sample because BNA doping decreased the rotational viscosity of the NLC. BNA dopant effectively suppressed the RMS error of LHLC lens addressed at the high voltage. Furthermore, the BNA dopant revealed a considerable absorbance for short wavelengths (< 450 nm), automatically providing the LHLC lens with a blue light filtering function for ophthalmic applications.

掺杂有机N-苄基-2-甲基-4-硝基苯胺的快速响应液晶透镜

在这项研究中，由向列型液晶（NLC，E7）和有机材料（N-苄基-2-甲基-4-硝基苯胺，BNA）的混合物制备了大孔径孔型液晶（LHLC）透镜。测量，比较和分析了掺杂和未掺杂样品的电光特性。掺杂样品表现出的响应时间比未掺杂样品快约6倍，因为BNA掺杂降低了NLC的旋转粘度。BNA掺杂剂有效地抑制了在高压下处理的LHLC透镜的RMS误差。此外，BNA掺杂剂对短波长（<450 nm）显示出可观的吸收率，从而自动为LHLC镜片提供了用于眼科应用的蓝光过滤功能。
