水解合成后得到的是羟基乙酸的水溶液，其中含有大量的氯化钠和少量未水解的氯乙酸及其它杂质，采用减压蒸馏及有机溶剂萃取方法进行精制是比较适宜。

In order to improve the solubility of the CNTs in solution without any structural damage, the surface-modified approach with noncovalent bond is considered. Anionic polyelectrolyte, poly(sodium 4-styrenesulfonate), used as modifier was applied to overcome the difficulty of CNT's dispersion into insoluble and infusible polymer matrix.

为了使奈米碳管在高分子基材中达到良好的分散性，又不会破坏其原始特性，本研究采用非共价键结表面改质的方式来进行奈米碳管之分散，研究中以阴离子型聚电解质，Poly(Sodium 4-Styrenesulfonate)，为奈米碳管分散剂。

Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides. The ν OO value ranged from 850 to 899 cm -1 varies regularly with the substituent on the phenyl ring.

合成了全氟和其它对位、间位取代的共10种过氧化苯甲酰，测定了它们的固体和溶液(溶剂为F113， CCl2FCClF2)的激光拉曼光谱，首次发现这类化合物中高度对称的过氧键有较强的特征谱带，即νOO在850至899 cm-1之间，并随取代基不同而呈现规律变化。

Diphenyl-5-pyrenyl-2-pyrazoline shows the emission characteristics of pyrene in solution or the emission characteristics of pyrazoline in films and bulk crystals.

但是，DPP超微粒则表现出了分别出自于芘坏386 nm、吡唑啉环465 nm和分子之间的吡唑啉坏-芘环电荷转移激子570 nm的三重发射，而且各自对应各自的激发光谱，即三重发射的光通道互不干涉。

This thesis includes two parts. One part studied the two photon excited luminescent properties of thirty pyridinium compounds in solution, another part studied the two photon excited luminescence properties of HMASPS and HEASPS in polymer matrix.

Moreover, the matrix effect was investigated. The results showed that samples could be completely decomposed by melting in lithium tetraborate and lithium carbonate mixed flux at about 1000℃. The introduction of lots of lithium and matrix magnesium in solution affected the determination, which could be corrected by matrix matching. Calcium, iron and aluminium with high content had no spectral interference with other elements with low content.

结果表明，样品用四硼酸锂和碳酸锂混合熔剂在1000℃左右的温度下熔融，可以完全分解试样；引进试液中大量锂和基体铁时测定有影响，用基体匹配的方法克服，含量较高的钙、铁和铝对含量低的其他元素没有光谱干扰。
