Abstract
本发明公开一种如通式(I)所示的芴类多官能度光引发剂。该化合物合成简单、成本低、溶解性好,在光固化组合物中应用效果佳,相比于传统小分子光引发剂,不仅光引发活性优异,而且具有低迁移性、低气味性、耐黄变等优点。
Description
技术领域
本发明属于有机化学领域,具体涉及一种芴类多官能度光引发剂及其制备,以及该引发剂在光固化领域中的应用。
背景技术
传统小分子光引发剂具有优异的感光性能和溶解性,但在实际应用中存在光解碎片容易迁移和挥发性大等问题。人们设法通过增加化合物分子量来解决这些不足,但是分子量增加通常会降低光引发效果。
芴类化合物分子量较大,且在紫外光固化中的应用已被本领域所熟知。若能将芴类化合物与传统小分子光引发剂的优势相结合,制成多官能度光引发剂,那么不仅能够降低光引发剂分子及其光解产物的迁移作用,缓解挥发性问题,而且有望通过多个不同光活性基团彼此之间的共同作用乃至协同作用,提高光引发效率,进一步提高其在感光性组合物中的应用性能。因此,寻求具有这种结构和特性的光引发剂化合物具有很高的应用价值。
发明内容
本发明的目的首先在于提供一种芴类多官能度光引发剂。该化合物合成简单、成本低、溶解性好,在光固化组合物中应用效果佳,相比于传统小分子光引发剂,不仅光引发活性优异,而且具有低迁移性、低气味性、耐黄变等优点。
本发明所述的芴类多官能度光引发剂,具有如下式(I)所示的结构:
其中,
R1各自独立地表示氢、卤素、C1-C20的直链或支链烷基、C4-C20的环烷基烷基、C2-C20的链烯基;
R2和R3相互独立地表示C1-C20的直链或支链烷基、C3-C20的环烷基、C4-C20的环烷基烷基、C4-C20的烷基环烷基、C6-C20的芳基,且R2和R3可彼此相连以形成环;
R4表示光活性基团;
A表示氢、硝基、卤素或-CO-CR2R3R4基团。
作为优选技术方案,在上述式(I)所示多官能度光引发剂中,R1各自独立地代表氢、卤素、C1-C10的直链或支链烷基、C4-C10的环烷基烷基。进一步优选地,R1各自独立地代表氢、C1-C4的直链或支链烷基、被C3-C6环烷基单取代的C1-C3烷基。
优选地,R2和R3相互独立地表示C1-C10的直链或支链烷基、C4-C10的环烷基烷基,或R2和R3彼此相连以形成C3-C10的环烷基。进一步优选地,R2和R3相互独立地表示C1-C4的直链或支链烷基、C4-C8的环烷基烷基,或者R2和R3彼此相连以形成C3-C6的环烷基。
优选地,R4表示羟基或者N-吗啉基。
优选地,A表示氢、硝基、或-CO-CR2R3R4基团。当取-CO-CR2R3R4基团时,R2、R3和R4具有如上所述的相同定义。
本发明还包括上述式(I)所示芴类多官能度光引发剂的制备方法,包括以下步骤:
(1)傅克反应
原料a与原料b在三氯化铝或氯化锌的催化作用下于有机溶剂中发生傅克反应,得到中间体a,
(2)溴代反应
中间体a在溶剂存在条件下与液溴发生溴代反应,生成中间体b,
(3)脱卤反应
中间体b经水解或者与含非羟基光活性基团的化合物反应,得到目标产物,
本领域技术人员容易理解的是,当原料a是仅由R1取代的芴(即A取H)时,通过调整反应原料比例,可以使A保留为氢或者经傅克、溴代和脱卤反应成为-CO-CR2R3R4基团,从而得到两种不同结构的产物。
上述制备方法中,使用的原料均是现有技术中的已知化合物,可通过商业购得或者经已知的合成方法简便地制备而成。并且,步骤(1)-(3)中涉及的反应都是本领域合成类似化合物的常规反应。在知晓了本发明公开的合成思路的基础上,具体反应条件对本领域技术人员而言是容易确定的。
步骤(1)的傅克反应中,反应温度通常为-10-30℃。对反应中使用的有机溶剂种类并没有特别限定,只要能够溶解原料且对反应无不良影响即可,优选二氯甲烷、二氯乙烷、苯、二甲苯等。
步骤(2)的溴代反应温度通常为30-50℃。对使用的溶剂种类并没有特别限定,只要能够溶解原料且对反应无不良影响即可,优选二氯甲烷、二氯乙烷、苯、二甲苯等。
在步骤(3)的脱卤反应中,中间体b通过水解或者与包含非羟基光活性基团的化合物反应,在结构中引入光活性基团,从而生成目标光引发剂。
中间体b通过水解进行脱卤时,可在R4位置引入羟基。除中间体b之外,反应体系中还包含由有机溶剂和水构成的溶剂体系以及无机碱和相转移催化剂。所述有机溶剂可选用二氯甲烷、二氯乙烷、苯、二甲苯、乙腈等;所述无机碱优选KOH、NaOH等无机强碱;所述相转移催化剂优选是季铵盐类相转移催化剂,如四丁基溴化铵、四丙基溴化铵、四正丁基铵、氯化三乙基苄基铵、硫酸氢四丁基铵等。水解反应温度通常为60-150℃。
中间体b通过与包含非羟基光活性基团的化合物反应进行脱卤时,可在R4位置引入相应光活性基团,反应温度通常为40-160℃。反应体系中可根据需要选择使用或不使用溶剂,对使用的溶剂种类并没有特别限定,只要能够溶解原料且对反应无不良影响即可,优选二氯甲烷、二氯乙烷、苯、二甲苯、乙腈等。作为所述含非羟基光活性基团的化合物的实例,例如可以是吗啉、硫代吗啉等。
相应地,本发明还涉及上述式(I)所示光引发剂在光固化领域中的应用。
通过在芴类化合物中引入小分子活性基团,本发明的多官能度光引发剂相比于传统小分子光引发剂,不仅光引发活性优异,而且具有低迁移性、低气味性、耐黄变等优点,成膜性能优异。
