Three new aliphatic-aromatic polymers having naphthyl rings were prepared by the polycondenstion of dialdehydes or diketone monomers with 1,5-naphthalenediamine or 1,4-phenylenediamine. The monomers were prepared by the reaction of aromatic aldehyde or ketone with 1,6-dibromohexane. The molecular mass of the monomers was confirmed through E.I mass spectroscopy. The structures of monomers and polymers were characterized by 1HNMR, FT-IR, UV-Vis Spectroscopy, SEM and TG/DTA. Fluorescence emissions of monomers and polymers were recorded and their quantum yields were calculated, all the compounds showed fluorescence property and indicated violet, blue-green, orange and red light emissions. The quantum yields of the polymers were obtained within the range of 0.04 to 24.3%. The semicrystalline and amorphous nature of the polymers was analyzed through powdered X-ray diffraction. Antimicrobial activities of the polymers were examined against different bacterial and fungal species. Thin film forming ability of the synthesized polymers was evaluated by making their blends with PVC (poly vinyl chloride) in different w/w% ratios.
通过二醛或二酮单体与1,5-萘二胺或1,4-苯二胺的缩聚反应制备了三种含萘环的新型脂肪族-芳香族聚合物。单体通过芳香醛或酮与1,6-二溴己烷的反应制备。通过电子轰击质谱法确认了单体的分子量。通过1HNMR、FT-IR、UV-Vis光谱、扫描电子显微镜和TG/DTA对单体和聚合物的结构进行了表征。记录了单体和聚合物的荧光发射并计算了它们的量子产率，所有化合物均表现出荧光特性，并发出紫色、蓝绿色、橙色和红色光。聚合物的量子产率在0.04%至24.3%的范围内。通过粉末X射线衍射分析了聚合物的半结晶和非晶性质。检测了聚合物对不同细菌和真菌物种的抗菌活性。通过将合成聚合物与聚氯乙烯（PVC）以不同的w/w%比例混合来评估其成膜能力。
