Description

2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑及其制备、应用
(一)技术领域
本发明涉及一种新的化合物,2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物,以及其制备和应用。
(二)背景技术
非线性光学的目标之一是寻找在一定波长下同时具有强的非线性光学特性和超快时间响应的材料,以满足未来基于全光器件光计算的需要。众多的理论和实验已经证明,具有π电子共轭结构的有机分子材料是实现这一目标很有竞争力的材料。
偶氮类化合物是一类含有共轭大π电子体系的物质,已被发现具有较好的三阶非线性光学效应。它的这一效应与其在紫外或可见光波段存在的偶氮发色团π-π*强烈跃迁吸收带密切相关。接在偶氮发色团两端的基团的推-拉电子效应会显著地影响偶氮基团周围的共轭结构性质,从而导致上述π-π*吸收带的移动和展宽。实际上,偶氮基团π-π*跃迁在这类体系中的红移正暗示了体系电子的离域化程度增强,从而使得基态到激发态产生的跃迁偶极距增大,减少能隙,有利于提高材料的三阶非线性光学效应。
在这个研究过程中,发明人发现了一种新的化合物,2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物,以及其制备方法,和作为有机三阶非线性光学材料的良好应用。
(三)发明内容
本发明的目的是提供一种作为良好的有机三阶非线性光学材料的新化合物,以及其制备方法。
所采用的技术方案如下:
一种2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物,具有如式(I)所示的结构:
Figure C20061005231500041
一种制备所述的2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物的方法,式(II)所示的噻二唑重氮盐和间甲基苯酚在尿素存在下,于-10~15℃在C1~C8的醇溶剂中发生偶合反应得到所述的2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物,
Figure C20061005231500042
其中
Figure C20061005231500043
为下列基团:HSO4 -或RCOO-,R为C1~C5的烷基。
制备方法中,所述的噻二唑重氮盐与间甲基苯酚的物质的量比为1∶1~2,反应时间一般为1h到5h。
所述的醇溶剂的用量为间甲基苯酚质量的20~40倍。醇溶剂推荐选用甲醇、乙醇或异丙醇。
进一步,方法中所述的噻二唑重氮盐是由2-氨基-1,3,4-噻二唑与亚硝酰硫酸在-10~20℃的条件下于酸溶剂中发生重氮化反应得到,所述的2-氨基-1,3,4-噻二唑与亚硝酰硫酸的物质的量比为1∶1.2~1.5。
所述的酸溶剂推荐硫酸、乙酸或丙酸。酸溶剂的量为2-氨基-1,3,4-噻二唑质量的10~30倍。
由于原料2-氨基-1,3,4-噻二唑的碱性很弱,因此用强亲电性试剂亚硝酰硫酸对它进行重氮化,而且为了使反应完全,亚硝酰硫酸需过量20~50%,反应时间一般为30min到5h。
具体的,按照物质的量比,噻二唑重氮盐∶间甲基苯酚为1∶1.2,在尿素存在下,于-5~10℃在甲醇或乙醇中发生偶合反应1~5h,得到所述的2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物。反应结束后,产物可析出,然后过滤,洗涤,用重结晶或柱层析法提纯。
2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物可作为有机三阶非线性光学材料应用。2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑有机化合物具有π电子共轭结构。接于偶氮基团两边的噻二唑以及间甲基苯酚都是有效的供电子基团,从而使偶氮基团附近π电子的离域化程度增强,π-π*跃迁的能隙减小,跃迁偶极距增大。因此该材料具有较高的三阶非线性极化率χ(3),较高的非线性折射率n2和较高的二阶超极化率γ。对于非三阶非线性光学材料,是不存在三阶非线性极化率、非线性折射率和二级超极化率的。由于2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑不存在近共振或共振吸收,其三阶非线性光学效应主要来源于化合物的构型,且在共轭结构中的含硫杂环对二阶超极化率γ贡献显著。此外,该材料具有<110fs的超快时间响应。
本发明所述的2-[(2-甲基-4-羟基苯基)偶氮]-1,3,4-噻二唑化合物的化学合成方法,原料易得,操作简单,反应条件温和,具有广泛的实施价值。
