ABSTRACT: Polypyrrole (PPy) and its
derivatives containing different were
synthesized by the interfacial polymerization reaction using
ammonium per sulfate as oxidant, and were characterized by using
Fourier transform infrared, Ultraviolet/visible absorption, and Raman
spectroscopic techniques. The third-order nonlinear optical properties of all
samples were measured by using nanosecond Z-scan measurements at 532 nm. At the
identical mass concentration of 0.15 mg·mL-1, all PPy derivatives
exhibited an obvious reverse saturable absorption performance,
while the saturable absorption response was observed for PPy. In addition,
significant differences in their nonlinear optical performances were observed,
highlighting the influence on optical nonlinearity of the aromatic segments of
conjugated polymers.
