The present invention provides a diacetylene derivative represented by the following formula (A) which exhibits liquid crystallinity by itself and has a large refractive index anisotropy or does not exhibit liquid crystallinity by itself but exhibits a large refractive index anisotropy when added to a liquid crystalline compound:
R1-Sp1-(Ar1)
p
-(Ar3)
q
-(Phe)
r
-C≡C—C≡C-(Phe)
r
-(Ar4)
q
-(Ar2)
p
-Sp2-R2 (A)
(wherein R1 and R2 are a hydrogen, halogen, cyano, isothiocyanate, alkyl, alkenyl, alkynyl or reactive group, SP1 and SP2 are each a spacer group, Ar1 and Ar2 are each a non-substituted or substituted aromatic carbocyclic or heterocyclic group, Ar3 and Ar4 are each a non-substituted or substituted heterocyclic group, Phe is a non-substituted or substituted 1,4-phenylene group, and p, q and r are each 0 or 1.
本发明提供了一种二乙炔衍生物,其由以下式(A)所表示,它本身表现出液晶性并具有大的折射率各向异性,或者虽然本身不具有液晶性,但当添加到液晶化合物中时表现出大的折射率各向异性:R1-Sp1-(Ar1)p-(Ar3)q-(Phe)r-C≡C—C≡C-(Phe)r-(Ar4)q-(Ar2)p-Sp2-R2 (A)(其中,R1和R2分别是氢、卤素、氰、异硫氰酸酯、烷基、烯基、炔基或反应基,SP1和SP2分别是间隔基,Ar1和Ar2分别是非取代或取代的芳香环烷基或杂环烷基,Ar3和Ar4分别是非取代或取代的杂环基,Phe是非取代或取代的1,4-苯基基团,p、q和r分别为0或1。)
