Description
技术领域
本发明涉及新材料有机化学品技术领域,特别涉及一类新的含有硫杂蒽酮为共轭结构的硫鎓盐类化合物,其化学制备工艺技术,其作为辐射固化光敏引发剂的用途,以及其在辐射固化配方产品,特别是在UV-Vis-LED光固化涂料或油墨,等诸多场合的应用用途。
背景技术
光生酸剂是一类在外界光刺激下能够产生强酸的化合物。众所周知,光生酸剂由于本身具有良好的化学增幅特点,而被广泛应用于化学增幅成像体系如微刻技术、规模集成电路制造、微电子学、微流体学、数据存储等领域。例如在微电子学领域,一种非常重要的技术就是制造微电路板,通过把一层含有光生酸剂的聚合物薄膜(光阻剂Photoresist)沉积在硅片的表面,然后用光通过掩膜来照射此聚合物薄膜,在曝光的部分产生强酸,从而对特定高分子树脂起到催化作用(交联或分解),使其发生量子产率≥1的反应,从而导致曝光区域发生相关的化学变化,与未曝光区域形成溶解或者亲和性能的差异,在显影处理后形成影像。这类催化作用就叫做“化学增幅效应”。而在光生酸剂体系中,离子型光生酸剂,例如碘鎓盐和硫鎓盐一直占据重要的地位。特别是三芳基硫鎓盐等。但是这些商品化的分子结构由于其共轭结构基本上是苯环,因此其最大吸收波长通常位于紫外区。这对于新光源的应用产生了一定的限制,例如发光二极管。
LED是发光二极管的简称,是目前发展起来的特殊光源。具有节能,环保,单色性好,使用寿命长等优点。与传统的高压汞灯、低压汞灯等相比体现出非常多的优势,特别是环保方面。因为不需要使用剧毒的汞,所以是目前被全世界各个国家都广泛采用的新型光源。但是LED也有其自身的局限性,主要在于其发射波长处于近紫外-近红外区域(365nm~),在紫外和远紫外区很难实现足够高的光强,从而引发一系列的应用。很明显,LED和硫鎓盐的激发是一对矛盾。
发明内容
针对上述现有技术的挑战,本发明已经出人意料地发现,一些经由新合成方法得到的含有硫杂蒽酮基团的硫鎓盐类化合物,具备与LED非常匹配的吸收波长,并且在如引入联苯基团后,体现出很好的光生酸性质。发明人进一步证实,这样的新型LED可激发的硫鎓盐类光生酸剂分子可以作为自由基或者阳离子光引发剂引发丙烯酸酯类或者环氧类单体的光聚合。特别是,这样的光引发剂适用于节能环保LED光固化技术,这样的技术对木器绿色涂装,环保印刷,喷墨打印,节能材料等领域拥有深远的影响。
本发明将硫杂蒽酮作为共轭结构,通过Suzuki-Miyaura反应制备联苯结构,在间位取代上硫鎓盐基团,从而合成一种新型的光生酸剂,能够在紫外-可见光区具有优秀的光吸收的性能。
本发明给出的技术方案如下:
本发明提出的一类以硫杂蒽酮为共轭结构的硫鎓盐型光生酸剂,该光生酸剂具有以下化学式:
其中,R1可以为甲基、苄基或4-氰基苄基中任一种;R2为三氟甲烷磺酸根、六氟磷酸根或四氟硼酸根中任一种。
本发明提出的一类以硫杂蒽酮为共轭结构的硫鎓盐型光生酸剂的制备方法,具体步骤如下:
(1)制备溴代硫杂蒽酮
在室温下,向单口烧瓶中加入浓硫酸,然后加入溴苯液体,室温下搅拌0.5~1.0小时,得白色浑浊液体,然后分批加入巯基水杨酸,室温下搅拌20-24小时,然后在100℃加热2~3h,冷却至室温后,小心倒入冰水中,抽滤,得到固体,然后加入20%的NaOH水溶液,搅拌2~3h,抽滤,水洗至中性,得黄色固体,即溴代硫杂蒽酮。
(2)制备目标光生酸剂前体
氮气保护下,在配有回流冷凝管和搅拌器的烧瓶中依次加入溴代硫杂蒽酮,3-甲巯基苯硼酸,碳酸钾,Pd(PPh3)4和toluene/ethanol/H2O做为反应溶剂,搅拌下加热回流24~48小时。冷却到室温后用二氯甲烷萃取,饱和食盐水和去离子水洗涤,蒸干溶剂后用硅胶柱色谱分离(淋洗剂:二氯甲烷/石油醚,1:2)得到浅黄色产物,即光生酸剂前体。
(3)制备目标光生酸剂
将光生酸剂前体溶于无水二氯甲烷中,将体系放置与干冰丙酮浴中降温至-78℃,之后在避光条件下加入等摩尔的三氟甲烷磺酸银和卤代烷烃或卤代芳烃,低温搅拌1小时。之后移除干冰丙酮浴,室温避光条件下搅拌22~24小时。薄板层析检测反应结束,将二氯甲烷蒸干,用乙腈溶解,滤去固体杂质,浓缩溶液,用10倍体积的乙醚沉淀,得产物,过滤,干燥,得黄色粉末,即为光生酸剂目标产物三氟甲烷磺酸盐。需要盐交换时,把三氟甲烷磺酸盐与相应的四氟硼酸盐、六氟磷酸盐、六氟锑酸盐在丙酮和水溶液中进行。抽滤干燥后即为特定目标产物。。
本发明中,步骤2)中所述的惰性气体为氮气或者氩气。
本发明中,步骤(3)中所述卤代烷烃可以采用碘甲烷,苄溴或4-氰基苄溴中任意一种。
本发明中,所述的3-甲巯基苯硼酸,碳酸钾,Pd(PPh3)4,卤代烷烃,卤代芳烃,三氟甲烷磺酸银和六氟磷酸钾和四氟硼酸钠均为市售产品。
本发明的特点是:
1.选择硫杂蒽酮作为光生酸剂母体。硫杂蒽酮本身是一种具有紫外-可见光吸收的生色团,可在紫外-可见光区有较好的光吸收性能;另外,它是电子密度很大的的电子给体,可同时能够增加共轭链段的长度和共面结构,从而改善光生酸剂在LED激发上的性能;
2.选用间位作为硫鎓盐结构的取代位置,能够利用光生酸剂结构中C-S键的断裂,从而促进光酸的生成;
3.合成过程简单,步骤较少,提高了产率;
4.最大吸收波长发生了红移,具有良好的紫外-可见光吸收性能,适用于成本更低、效率更高的诸如385nm,405nm,425nm,450nm的紫外区到近可见光区的LED激发光聚合;
5.具有很高的化学稳定性,在黑暗室温的条件下,能够保持长时间的保存。
