  1. A method to calculate quantitatively the adsorption volume or adsorption space of per mass of adsorbent derived from both the adsorbed molecule volume and the maximum adsorbance of a solute in an adsorption isotherm under a given experimential condition is presented firstly for a solid / liquid adsorption system of the solute in a dilute aqueous solution. this method is suitable for not only mono - layer adsorption, but also mani - layer adsorption and micelle adsorpion of surfactant constructed by hydrophile and lipophile groups. therefore, the surface concentration of the adsorbate, cs, deduced from the adsorption volume is possessed of the meaning of true concentration, and the value of the patition coefficient of the adsorbate between solid and liquid phass, p, attained by the cs and the c, solution concentration of the adsorbate, can be accurate. the foregoing a set of calculations are presented for the solid - liquid adsorption systems consisted of the wool fiber and separately dodecyltrimethyl - ammonium bromide ( dtab ) and hexadecyltrimethyl - ammonium bromide ( ctab ) in this paper. this provides a strong basis for adsorption thermodynamic investigation of adsorbate

    對稀溶液中溶質的固/液吸附體系，首次提出了根據吸附分子體積和實驗條件下吸附等溫線中的最大吸附量計算單位質量吸附劑的吸附體積或吸附空間的方法.此法適用於單層吸附，也適用於多層吸附和具有親水親油結構的表面活性劑分子的膠團吸附.由此，吸附質的表面相濃度cs具有真實濃度的含義，相應地，計算得到的溶質的固/液分配系數p就有了準確值.分別計算由溴代十二烷基三甲銨（ dtab ）和溴代十六烷基三甲銨（ ctab ）與羊毛纖維構成的液/固體系分配系數等，為溶質吸附的熱力學研究奠定了基礎
  2. Recent progress in molecular design of organic second - order nonlinear optical chromophores with both large first - order molecular hyperpolarizability and good transparency

    兼具大的二階光學非線性與良好透明性的有機生色團的分子設計進展
  3. In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule

    本文報道首次以x ? l的層狀（脯氨酸十一甲基磷酸一磷酸氫）鉛（ a zpmpp ）為主體底物，成功地將客體分子：正丁胺、正慶胺、正癸胺、乙醇胺、二乙烯三股、三乙烯四胺、四乙烯五股插入層狀化合物a zpmpp的層間，通過紅外光譜（ ir ） 、 x射線衍射（ xrd ） 、熱重分析（ tg dsc ）等手段對插層復合物進行結構表徵，結果表明： x ? l的層狀（脯氨酸件一甲基磷酸一磷酸氫）鉛具有不同於無機磷酸結的插層性能，由於層間脯氨酸基團的體積較大，影響客體分子進入的數量，胺分子在層板間取單層排列。
  4. The classic synthesis methods of polycyclic aromatic hydrocarbons ( pah ), the most recent development in the synthetic methodology of the functional pah, their application to construction of complex architectures ( liquid crystals, shape persistent linear and cyclic macromolecules ), and their supramolecular behavior are reviewed in this article

    摘要對稠環芳香烴的合成方法、官能團化稠環芳香烴最新合成進展、官能團化稠環芳香烴構建的復雜分子體系（液晶、剛性線型和環狀的大分子）及其超分子化學進行了評述。
  5. Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process

    將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中，獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合，在分散體粒子內產生擴鏈交聯反應，生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明，此分散體具有極大的工業應用價值
  6. It also has stronger hydrogen bond which can result in partly physical crosslinkage in polymers, which can fasten orienting of chromophore. all these benefit to obtain high nlo coefficient. in chapter one, some basic conceptions about lc and the advance in lcpu are described, especially the synthesis methods on lcpu and the influence factors of lcpu formation liquid crystalline phase

    聚氨酯液晶是分子排列具有一定取向的聚合物材料，可為非線性光學聚氨酯提供一種較好的非對稱取向的介質環境，聚氨酯中還存在較強的氫鍵作用，使得聚合物材料有部分物理交聯，能固定發色團的取向，這些因素有利於獲得較大的非線性光學效應。
