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.
通过Diels-Alder环加成反应,用茚〓和1,1'-联茚〓及取代茂合成了一系列可溶性的〓环加成衍生物,发现可控制反应条件,使1,1'-联茚与〓反应,并高产率地得到具有新颖结构的单加成物,用HPLC、FTIR、FD-MS 及〓、HMQC、HMBC等多种波谱技术对其结构进行表征,测得它的两个〓杂化的桥头碳的化学位移为〓ppm,证明生成的衍生物为6∶6闭式环加成,〓NMR谱中共给出38个信号,表明〓联茚衍生物分子具有〓对称性;在波长532nm,脉冲宽度8ns的激光下,〓联茚衍生物的甲苯溶液的光限幅性能与〓的甲苯溶液相近,由于〓联茚单加成衍生物熱稳定性好,在四氢呋喃,丙酮等极性溶剂中溶解性好,能分别均匀地掺入溶胶-凝胶中,已发现它的溶胶(so1)光限幅性能优于纯〓的光限幅性能;使用Langmuir-Blodgett技术将〓联茚衍生物在空气和水的界面进行了LB单层膜和多层膜实验以及UV-Vis吸收谱研究,通过等温压缩曲线测试,证明浓度为〓〓时,〓联茚衍生物能够形成单层膜。

When feeding with undecylenic acid by fed-batch culture, there was a lag time when microorganism using undecylenic acid as a new carbon source. The molar fraction of unsaturated monomer could be achieved by 37.39% at 73 hr cultivation. We can see the property of PHA become flexible with cultivation time by the lower of Tg.
发酵槽馈加十一烯酸培养实验,产物为PHO与PHU(poly-3-hydroxy-8-noneneoate为主)所形成之混掺物,且双键所占比例随时间增加,培养第73小时可得到双键比例37.39%;随培养时间增加,玻璃转移温度(Tg, glass transition temperature)由-34.03℃下降至-42.40℃,显示PHA性质变得更加柔韧具有弹性。
