摘要：

We report the first-order hyperpolarizabilities (bHRS values) of individualized, length-sorted (700 +/- 50 nm long) (6,5) SWNTs and corresponding polymer-wrapped (6,5) SWNT superstructures. These SWNT-based nano-hybrids 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 bHRS at long wavelength (1280 nm).
