We report the first-order hyperpolarizabilities (β values) of individualized, length-sorted (700 ± 50 nm long) (6,5) SWNTs and corresponding polymer-wrapped (6,5) SWNT superstructures. These SWNT-based nanohybrids feature semiconducting polymers that wrap the SWNT surface in an exclusive left-handed helical fashion. Manipulation of the polymer electronic structures in these well-defined nanoscale objects provides a new avenue to modulate the magnitude of β at long wavelength (1280 nm).
我们报告了个体化的、长度分类（700±50纳米长）的（6,5）单壁碳纳米管（SWNTs）以及相应的聚合物包裹的（6,5）SWNT超结构的一阶超极化率（β值）。这些基于SWNT的纳米杂化物具有以独特的左手螺旋方式包裹SWNT表面的半导体聚合物。在这些明确的纳米级物体中对聚合物电子结构的操控为在长波长（1280纳米）下调节β的大小提供了一条新途径。
