The thermal curing mechanism and property of low dielectric films based PPSQ were studied by FTIR, Gaussian curve fitting and Spectroscopic Ellipsometry.

FESEM测试表明PPSQ在485℃之前能得到平整致密的薄膜；在485～525℃由于苯基的氧化分解有致孔的效果，孔洞结构为圆孔；在525℃之后圆孔将变成连孔，薄膜在局部将变得致密。

The membrane micro-structure and its selectivity could be tailored by controlling the mole ratio of PTMOS to TEOS.

通过控制前驱物中的苯基的含量，即PTMOS／TEOS的比值，可以设计膜的结构和分离性能。

Cinnabarinus at 150 mg/L.The influences on bioactivity of substituted pyrazole and pyrimidine were discussed respectively: pyrazoles substituted with phenyls at 3 position had higher activity than thiophen and compounds with R_1=methyl had higher activity than that with R_1= hydrogen, pyrimidines substituted with methyl at 2 (R_3) and 5 (R_3) position and phenyl at 6 position were most active.

本论文对吡唑及嘧啶取代基对活性的影响分别进行了讨论，可知：吡唑3位为取代苯基的化合物杀菌活性优于取代噻吩的，吡唑4位(R_1)为甲基的杀菌活性高于R_1为氢的活性；嘧啶的2位(R_3)为甲基，5位(R_1)为甲基，6位为无取代基的苯基时活性最好。

So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。

When equimolecular ratio of the reactants was used, the addition products were 1-phenyl-2-phenylthiopropene-1and 1-phenyl-2-phenylthiobutene-1, respectively.

这加成反应是按自由基机理进行，苯硫基联结在与烷基相邻的碳原子表明中间生成的自由基之稳定性是加成方向的决定因素，因为苯基的共轭效应比烷基为强。

1H NMR and 13C NMR spectra were acquired at room temperature with a 500 MHz spectrometer and referenced to residual 1H and to 13C present in deuterated solvents.

GC-MS光谱是测量在与熔融石英血丝的一台仪器专栏(被交互相联的5%苯基的甲醇硅树脂)。
