arylene, and R
1
is hydrogen or an organic radical,
with the proviso that when R
1
is hydrogen and A
2
is 1,2-phenylene, A
1
is not 9,10-anthraquinon-1,2-ylene, 4-chloro-3,5-dimethyl-1,2-phenylene or 3,5-dimethyl-1,2-phenylene, processes for their preparation and the use thereof.
化合物Ia和Ib的式子为trans-(Ia)和cis-(Ib),化合物IIa和IIb的式子为trans-(IIa)和cis-(IIb)。其中,A1和A2各自独立地是未取代或取代的ortho-C6-C18芳基烃,取代基可以是单一到四个,而R1是氢或有机基团。但要注意,当R1为氢且A2为1,2-苯基烃时,A1不能为9,10-蒽醌-1,2-亚基烃,4-氯-3,5-二甲基-1,2-苯基烃或3,5-二甲基-1,2-苯基烃。本文还介绍了制备这些化合物的方法以及它们的用途。
