Description
技术领域
本发明涉及共轭聚合物，具体属于一种光动力杀菌聚合物及其制备方法和应用。
背景技术
自从青霉素被发现以来，许多抗生素接连被报道，在一段时间内起到了很好的杀菌效果。然而抗生素的广泛使用和滥用，导致耐药菌不断出现，人们迫切需要新的有效的抗感染方法。
与抗生素相比，光动力杀菌疗法利用光敏剂在光照下产生活性氧(包括单线态氧、超氧阴离子自由基、过氧化氢、以及羟基自由基等)来损伤细菌并致病菌死亡，且不会使细菌产生耐药性，优势更加突出。其中光敏剂是重要的一个元素，发展性能良好的光敏剂可减少使用剂量及光照强度，减少对正常组织的伤害。
共轭聚合物由于其良好的光电性质，近年来被广泛应用于生物医疗领域。在光照条件下，共轭聚合物可以直接敏化周围的氧气分子产生活性氧，从而发挥杀菌作用。季铵盐类化合物已经被证明能够与细菌膜发生静电吸引，增强细菌膜的通透性达到杀死细菌的目的。将共轭聚合物的光活性与季铵盐的杀菌活性结合，实现对细菌的快速杀伤，对于治疗因致病菌引起的感染有重要意义。然而，目前已经报道的季铵盐类化合物杀菌效果一般，杀菌范围有限，如只能杀细菌，不能杀真菌等，鉴于此，获得杀菌性能优良且广谱的抗菌材料是本发明的宗旨。
发明内容
本发明的目的是提供一种光动力杀菌聚合物及其制备方法和应用；所述的聚合物在光照射下具有高的杀菌活性，可作为光动力杀菌剂应用；所述聚合物制备方法操作简单、反应条件温和、产率较高。

2)、氮气保护下，按摩尔比1∶2.5∶6，将2,7-二溴芴、频哪醇硼酸酯和醋酸钾加入二氧六环中，再加入催化量的Pd(dppf)2Cl2，加热到110℃搅拌反应12h，得到2,7-二(4,4,5,5-四甲基-1,3,2-二氧杂硼酯)芴(III)；反应式如下：
3)、氮气保护下，按摩尔比1∶2∶1，将1,4-二溴-2,5-二(12-溴十二烷氧基)苯(II)、2,7-二(4,4,5,5-四甲基-1,3,2-二氧杂硼酯)芴(III)和4,7-二(2-溴-5-噻吩基)-2,1,3-苯并噻二唑加入体积比为1∶5的碳酸钾水溶液和甲苯的混合液中，再加入催化量的Pd(PPh3)4，加热回流反应48h得中间体产物，经甲醇沉淀后所得中间体产物加入含有10倍当量三甲胺的三氯甲烷溶液中，40℃下搅拌反应48h，得到聚合物(I)；反应式如下：
本发明光动力杀菌聚合物具有广谱抗菌的功效，对革兰氏阴性菌(大肠杆菌Top10)和革兰氏阳性菌(金黄色葡萄球菌ATCC6358)以及真菌(白色念珠菌)都具有杀菌活性，尤其是在光照下，杀菌率达到94％以上，可作为杀菌剂应用。
本发明光动力杀菌聚合物在长波区发射荧光，也可在生物荧光成像中应用。
与现有技术相比本发明的有益效果：本发明得到的光动力杀菌聚合物由主链和侧链组成，侧链由末端季铵化的长烷基链构成，能够与带负电荷的细菌表面结合并形成紧密的组合体，使细菌膜通透；主链由苯、芴及噻吩组成，具有较强的刚性结构，在光照的条件下，受光激发敏化周围的空气产生活性氧，达到高效杀菌效果。该聚合物可作为杀菌剂应用，具有光谱抗菌的能力，不仅能够杀伤真菌，而且对细菌也有强的杀伤能力。该聚合物制备方法简单、反应条件温和、产率较高。该聚合物杀菌所需浓度低、光剂量小，普通白光照射就能达到高效的杀菌效果。本发明聚合物在长波区发射荧光，还可用于生物荧光成像。
