Abstract
式Ⅰ的液晶化合物X(-Y-A-Y-M-Y-B)n(Ⅰ)其中X为一n价脂肪族,芳香族或环脂肪族基团,或为一n价链烯基或炔基;n为2,4或5;每个Y彼此独立,可为直接键,-COO-,-OCO-,-O-,-CONH-或-CON(R)-,其中R为C1-C4烷基;A为一间隔基;M为一液晶基元基团和B为一侧链。此液晶化合物特别适于信息显示。
Description
目前大量的液晶化合物已为人知。然而,这些化合物通常不能以玻璃体方式固化。具有液晶性,且可以玻璃体方式固化的确定化合物例如在专利DE-A 3703640,DE-A 3827603,DE-A 3830968和EP-A-504 660中已有描述,在前三个申请中,所描述的化合物存在一个共同特征:其容易结晶,甚至是从玻璃态。这样在凝固态的取向也就不稳定。由于在晶体中形成混晶对分子的要求比在各向异性流体中混合的要求要强烈的多,在这种结晶情况下,所采用的任何混合物也不再稳定。
专利EP-A-504 660所描述的化合物可形成稳定的玻璃体,其拥有与分子长轴平行的高偶极矩,并可形成向列型或近晶型A相,由于沿着分子长轴的偶极矩,这些物质在电场中平行取向,其因此不具备铁电性,同时在电场中所显示的任何螺旋超级结构均不稳定。
此外,所知的液晶体系有一个确定的结构,其中液晶基元(mesogen)基团通过一个间隔基与中心单元相连(如专利DE-A-40 118117)然而这些物质并不能以玻璃体方式固化,但相应地由于其高对称性,结晶极易发生。此外,
液晶(Liquid crystals 11(5)(1992),779)描述了一种通过间隔基与中心单元相连的铁电性液晶,这些物质具有对热、弱酸或碱、水不稳定的液晶基元结构。
期望作为液晶铁电性材料的化合物,其应为那些物质:有一个相特性,在经过冷却过程所表现的相序为向列型、近晶型A和近晶型C。同时为防止显示表现出压敏性,材料应有高粘流性,而且尤其应对弱酸和碱稳定。此外,更高的期望特征是具有与其他液晶化合物好的混合性。
本发明的目的是提供全新的液晶混合物,其可以以玻璃体方式固化,具有近晶和向列相。对温度和PH的变化、水不敏感,且有高的粘流性。
我们已发现这一目的可用式I的化合物来实现:
X(-Y-A-Y-M-Y-B)n I
其中,X为一n价脂肪族、芳香族或环脂肪族基团或为一n价链烯基或炔基,
n为2,4或5
每个Y彼此独立,可为直接键、-COO-、-OCO、-O-、-CONH,或-CON(R)-,其中R为C1-C4烷基,
A为一间隔基,
M为一液晶基元基团,
且B为一侧链。
X基团的实例有:亚烷基,
或可被O,NH或NR间断的亚烷基,
各个亚烷基的实例:
其中p为1-20,优选1-10,R在这里有特定的说明,
n优选2或4。
至于Y基团,尤其优选-OCO-,-O-,和-COO-,
可采用的间隔基均为那些已知用于此目的基团,间隔基通常通过酯或醚基或直接键与X相连。间隔基通常有2-30,优选2-12,尤其为6-12个碳原子,且可被例如O,S,NH或NCH3间断。间隔链的合适取代基为氟、氯、溴、氰基、甲基和乙基。
代表性的间隔基实例为:(-CH2)p-,-(CH2CH2O)mCH2CH2-,-CH2CH2SCH2CH2-,-CH2CH2NHCH2CH2-,
其中,m为1-3,p为1-12。
M可为一已知的液晶基元基团,尤其适合的为包含芳族或杂芳族基团的基团,尤其是液晶基元基团符合式III:
(-T-Y1)r-T III
其中,每个T彼此独立,可为一芳香或杂芳基团
每个Y1彼此独立,可为-O-,-COO-,-OCO-,-CH2O-,-OCH2-,-CH=N-或-N=CH2-,或直接键
r为1-3,r优选1或2,
Y1优选-COO-,-OCO-,或直接键。
侧链B的实例为C2-C30烷基或链烯基,优选C2-C11烷基或链烯基,其中基团可为线性或支化的,可一次或多次为-O-,-OCO-,-COO-,
-NH-或-N(CH3)-间断,也可为苯基,F、Cl、Br、CN或OH取代。
B尤其优选经-O-,-COO-或-OCO-连接的C3-C11烷基,且可一次或多次为O间断,优选非支化的。
各个B基团的实例为:
-C2H5,-C3H7,-C4H9,-C5H11,-C6H13,
-CH2CH=CH2,-(CH2)7CH=CH2或-(CH2)8CH=CH2.
手性侧链B的实例为
其中R1为C1-C12烷基,可为手性或非手性,R2可为基团R1,F,Cl。
优选的R1基团实例为:
其中,p为1-12。
在式I的化合物中,与X相邻的桥元Y为-COO-、-CONH,或-CONR,为了制备这种化合物,分子式为X(COCl)n的酰氯可与下式的化合物
HO-A-Y-M-Y-B,
以本来已知的方法反应。如果与X相邻的Y为桥元-OCO-,则分子式为X(OH)n的化合物可类似地与下式的化合物反应,
如果桥元Y为O,则羟基与卤代烷基反应。
-般的制备方法可从文献中获悉,值得一提的一个实例为用二环己基碳化二亚胺(DCC)反应制备酯,反应的详细情况在实例中给出,其中的份额与百分比除特别说明外均以重量计。
式I的化合物为液晶化合物,且依据结构不同,可形成近晶相,向列相或胆甾相。其适合于液晶化合物通常所应用的所有目的。
全新的化合物处于低分子量与聚合的液晶化合物间的中间位置,与聚合物相比,其可重复制备,具有真正统一的结构,然而却有聚合物的粘度。
为了得到期望的性质,利用式I的化合物的混合物是有利的,可就地制备,即合成时或通过机械混合制备这些混合物。
新化合物可单独地,相互混合地或与其他液晶一起用在光学信息显示装置中,其尤其适合用于显示和生产反光涂层。
