We have measured the third-order optical nonlinearity of the organic-inorganic hybrid materials of supermolecules (C19H25N2)(7)H-n[P2Mo18-nVnO62] (n = 1,2,4,5) and their reactants (C19H25N2)Br and Hn+6[P2Mo18-nVnO62] by using the ultrafast optical Kerr effect at 830nm wavelength, with time resolution of 115 fs. By comparing the gamma values of the supermolecules and their reactants, it is concluded that the charge-transfer enhanced remarkably the third-order optical nonlinearity of the compounds. With the increment of the number of the vanadium atoms, the electron distribution changed strongly and the gamma value decreased dramatically.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyU...
