Synthesis of Novel Monomeric Dyes with Anthraquinone Residue

Two novel polymerizable dyes with anthraquinone residue have been prepared, and their structures were characterized by FTIR, ^1HNMR and EA.     

Synthesis and Photocytotoxicity of Mono-functionalised Porphyrin with Valine Moiety

A mono-funtionalised tetraphenylporphyrin (TPP) bearing valine moiety at the phenyl ring was synthesized for photocytotoxicity examination in four steps, starting from regiospecific mono-nitration of TPP at the phenyl ring. The in vitro photocytotoxicitic effect against SPC-Al adenocarcinona cell line was tested.     

Studies on Synthesis and properties of Mg-Al-nitrate Layered Ouble Hydroxides

A positive Mg-Al-nitrate layered double hydroxides(LDHs) has been synthesized using a non-steady coprecipitation method.The shape.size,chemical composition,electrical property and anion exchange property of the positve nanoparticle were studied by SEM,XRD,FTIR,chemical analysis,spectroanalysis and meaxsuring of electrophoretic mobilities.Preliminary results show the positive nanoparticle is a promising precursor of polymer/LDHs nanocomposite.

偶氮接枝的聚氨酯薄膜光谱响应特性的实验研究

利用旋涂法，通过接枝共聚的方法制备了具有偶氮侧基的聚氮酯高分子聚合物薄膜。并利用二倍频YAG激光（532nm）作为激发光，白光光源作为参考光，在室温下测试了该薄膜在激发光作用前后的吸收光谱，发现该薄膜在430nm-530nm内有较强的吸收。以及随着激光能量的增大和撤去激发光后，随着无光照时间的延长，360nm与500nm波长处吸收强度的变化趋势。     

2—（4,6—二甲基—2—嘧啶巯基）乙酰芳胺的合成及其生物活性的初步研究
