Abstract
Multiwalled carbon nanotubes (MWNTs) bonded with an amino-moiety-containing nonlinear optical (NLO) polymer, poly{[3-octylthiophene-2,5-diyl]-[p-aminobenzylidenequinomethane]} (POTABQ), were synthesized via amidiation reaction and were characterized using transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) spectroscopy, ultraviolet-visible absorption spectroscopy (UV-vis), and fluorescence (FL) spectroscopy. The micrograph of POTABQ-MWNTs showed a "bead-shaped structure", which indicated that the polymer was attached to the tubes by chemical linkage rather than as a homogenous coating. POTABQ-MWNTs showed fluorescence quenching, which is involved in the intramolecular photoinduced charge transfer process. A broad absorption band appeared at over 800 nm, indicating the ground-state interaction between POTABQ and MWNTs. Third-order NLO properties were studied by nanosecond degenerate four-wave mixing (DFWM) techniques. The resulting POTABQ-MWNTs exhibited large third-order NLO responses mainly due to the formation of an intramolecular photoinduced charge transfer system of polymers and carbon nanotubes.
