The IR absorption spectra of PPD was observed at 830~840cm-1, which was assigned to the skeletal vibrations of the phenazine ring. The UV-vis absorption spectra of PPD was at 430nm in dimethyl sulfoxide. Through the analysis of thermogravimetry and derivative thermogravimetry of PPD, the PPD powders char yield at 850 C, which exhibited perfectly stability.

之间有吩嗪环特征吸收峰，说明聚邻苯二胺含有吩嗪环结构；用紫外—可见光谱研究聚合物的吸收峰，发现聚合物在430nm附近有很强的吸收峰；由热重分析发现聚合物在850℃时炭化，所以聚合物有较高的热稳定性。

The preparation of a novel porphyrin derivative bearing oligo( p -phenylene) group and its zinc complex was reported, which involved a microwave irradiation and a synthesis based on the template effects, respectively.

利用微波反应和模板效应合成了带有苯乙烯撑单元的新型卟啉化合物和锌卟啉配合物。

Winckelmann, the spokesman for philhellenism, extolled Greek art and dismissed all Roman art as derivative and Virgil as second rate and incapable of understanding true beauty.
