Description
已知有大量液晶化合物。但是它们一般不以类似玻璃的方式固化。具有液晶性质并以类似玻璃的方式固化的已知化合物公开于诸如DE-A 37 03 640、DE-A 38 27 603、DE-A 38 30 968和EP-A-504 660等。前三份申请所叙述的化合物的共同性质是它们甚至易于从玻璃态结晶,并因此在凝固状态下的取向不稳定。在结晶的情况下所采用的任何混合物也不再稳定,这是由于分子在晶体中形成混晶要求比在各向异性流体中对掺混性要求高得多。
EP-A-504 660中所述的化合物形成稳态玻璃体。它们具有很高的平行于分子长轴的偶极矩,并且形成向列型或近晶状A型相。沿分子长轴的偶极矩意谓着这些材料在电场中与分子长轴平行排列,因此它们不具有铁电特性,而且存在的螺旋超结构在电场中是不稳定的。
还已知具有一种确定结构并且其中介晶基团(mesogenic group)经一个间隔基团(spacer)与中心单元(central unit)键合的液晶体系(例如DE-A-40 11 811)。但是,这些材料虽然不以与玻璃类似的方式固化,但由于具有高度对称性,它们还是非常易于结晶。此外,Liquid Crystals 11(5)(1992),779页描述了经一个间隔基团与中心单元键合的铁电液晶。这些材料具有对热、弱的酸碱和水不稳定的介晶结构(mesogenic structure)。
用作液晶铁电材料的理想化合物是那些在冷却过程中经历向列型、
近晶状A型和近晶状C型的相变化的化合物。另外,这些材料应该具有高流动粘度以防止其显示是压敏的,并且尤其是应该对弱的酸碱稳定。此外最好具有与其它液晶化合物较好的掺混特性。
本发明的一个目的是提供新型的液晶化合物,这些化合物以类似玻璃的方式固化,并具有近晶状和向列型相,对温度和pH值的变化、对水均不敏感,并且具有高流动粘度。
我们已经发现这一目的通过下式I的化合物而实现
X(-Y-A-Y-M-Y-B)n I,其中X是芳族或脂族环系;n是2到6的整数;每个Y彼此互相独立地为直接键、-COO-、-OCO-、-O-、-CONH-或-CON(R),其中R是C1至C4烷基;A是间隔基团;M是介晶基团;和B是侧链。
X优选是三取代的苯基或环己基,其中取代基特别是相互为间位。
在基团Y中,特别优选的是-OCO-、-O-和-COO-。
已知的用于间隔目的的所有间隔基团都可在此充当间隔基团,这些基团通常经酯或醚基团或经直接键与X相联。间隔基团一般具有2到30个碳原子,优选2到12个碳原子,并且可在链上被诸如O、S、NH或NCH3间隔。合适的间隔基团链的取代基是氟、氯、溴、氰基、甲基和乙基。
代表性的间隔基团的例子包括:
(CH2)p,(CH2CH2O)mCH2CH2,CH2CH2SCH2CH2,CH2CH2NHCH2CH2,或
其中m是1到3;和p是1到12。M可以是已知的介晶基团。特别合适的是含有芳基或杂芳基的基团。具体地说,介晶基团符合式III:
(-T-Y1)r-T III,其中每个T彼此互相独立地为芳基或杂芳基;每个Y1彼此互相独立地为O、COO、OCO、CH2O、OCH2、CH=N、N=CH或直接键,和r是1到3。r优选1或2。
T一般是芳香碳环或杂环系,并可以被氟、氯、溴、氰基、羟基或硝基取代,例如符合下列基本结构: 或
特别优选的介晶基团M的例子包括: 或
测链B的例子包括C2至C30烷基或链烯基,优选C2至C11烷基,其中基团可以是直链或支链,可以被O、OCO、COO、
NH或N(CH3)间隔1次或多次,并且可以被苯基、氟、氯、溴、氰基或羟基取代。
单个基团B的例子包括:C2H5、C3H7、C4H9、C5H11、C6H13、C7H15、C8H17、C9H19、C10H21、C11H23、C12H25、CH2CH=CH2,(CH2)7CH=CH2或(CH2)8CH=CH2.手性侧链B的例子包括: 或其中R1是C1至C12烷基,并可以是手性或非手性的,R2是R1、氟或氯。
优选的基团R1的例子为:CpH2p+1,
或
其中p从1至12。为了制备式I化合物(其中与X相邻的Y是COO、CONH或
而且n是3),式X(COCl)3的羧酰氯可以与下式的化合物用本身已知的方法反应。HO-A-Y-M-Y-B.H2N-A-Y-M-Y-B,或
对于n=3并且Y=与X相邻的OCO式X(OH)3的化合物可以类似地与式ClOC-A-Y-M-Y-B的化合物反应。
对于Y=O,羟基可以与卤代烷基反应。
对于n≠3的化合物,则相应地应用,即一般的制备方法可从文献得知,可能被提及的一个例子是与二环己基碳二亚胺(DCC)反应制备酯。在实施例中给出了此反应的细节,其中的份数及百分数若无特殊说明则均以重量计。
式I的化合物是液晶性质的,而且根据结构不同可以形成近晶状、向列型或胆甾醇型相。它们适用于液晶化合物所有的常规用途。
新型化合物介于低分子量液晶化合物和聚合液晶化合物之间。与聚合物相比,它们能够再生地制得并且具有基本均一的结构,但又具有类似聚合物的粘性。
为了得到所需的性质,最好使用式I的化合物的混合物,这样这些混合物就有可能当即制得或通过机械混合来制备。
本新型化合物尤其适用于显示以及用于生产反光涂料。
