The Diels-Alder cycloadditions of [60] fullerene for preparation of optical limitingmaterials are discussed in chapter 3 and 6. Soluble cycloaddition derivatives of 〓aresynthesized by the reaction of 〓 with indene,1,1'-biindene andcyclopentadiene derivatives.〓Particular, the Diels-Alder cycloaddition of 〓 with1,1'-biindene under controlled conditions affords the stable monoadduct 〓〓of novel structure, which was confirmed by HPLC, FTIR, FD-MS,〓NMR,〓 NMR, HMQC and HMBC spectra, Its two bridgehead cage carbons resonate at70.91ppm, The 〓 NMR spectra showed 38 lines consistent with the 〓 symmetryassociated with [6,6] addition. The 〓 shows similar optical limitingproperties to that of 〓 in toluene for 8ns laser at wave length 532nm. Moreover, thehigh solubility of this adduct in polar solvents such as THF, acetone enables itsincorporation into sol-gel glass matrix. The thin films prepared via the sol-gel methodshow improved OL behaviour compared to those of 〓. The langmuir-Blodgett filmformation and uv-visible absorption of 〓 are also investigated. LBmonolayer of this compound is prepared on the air-water interface at 〓 mol/l. In chapter 4, three water-soluble derivatives of [60] fullerene: fullerol(1), theaddition product (2)of fullerol (1)with polyvinylpyrrolidone and fumaric acidderivative of 〓(3) are synthesized and characterized.

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.
