Molybdenum(VI) tris(dithiolene) complexes as a new class of three-dimensional two-photon absorptior chromophores at telecommunications wavelengths

摘要

Two molybdenum(vi) tris(dithiolene) complexes with phenyl or naph-thyl substituents were synthesized and their two-photon absorption properties were investigated by an open-aperture Z-scan technique using near-infrared femtosecond laser pulses. Both of these complexes exhibited significant two-photon cross sections around the wavelength of 1.3 nm, with the naphthyl substituted complex showing a two-photon cross section of 660 x 10~(-50) cm~4 s~(-1) photon~(-1), suggesting a new class of three-dimensional chromophore for use at telecommunications wavelengths.
