We report the synthesis of new asymmetric dihetarylethenes - 4-[5-(4-bromophenyl)-2-methylthiophen-3-yl]-3-(5-methoxy-1,2-dimethyl-1H-indol-3-yl)furan-2,5-dione and 1-alkyl(phenyl)-3-(5-methoxy-1,2-dimethyl-1H-indol-3-yl)-4-[5-(4-bromophenyl)-2-methylthiophen-3-yl]-1H-pyrrole-2,5-diones, which exhibit photo-chromic and fluorescent properties in solution. Thermally stable photoinduced cyclic isomers were observed for dihetarylethenes derived from 5-methoxy-1,2-dimethylindole and 5-(4-bromophenyl)-2-methylthiophene, unlike for their structural analogs based on 5-methoxy-1,2-dimethylindole and unsubstituted thiophene. Changing the thiophene fragment of dihetarylethenes to a 5-(4-bromophenyl)-2-methylthiophene fragment gave rise to photochromic properties in furan-2,5-dione derivatives.

The present invention provides a novel aromatic amine derivative having a specific structure and an organic electroluminescence device in which an organic thin film layer comprising a single layer or plural layers including at least a light emitting layer is interposed between a cathode and an anode, wherein at least one layer in the above organic thin film layer, particularly a hole injecting layer contains the aromatic amine derivative described above in the form of a single component or a mixed component. Use of the aromatic amine derivative described above materialize an organic electroluminescence device which reduces an operating voltage and makes molecules less liable to be crystallized and which enhances a yield in producing the organic EL device and has a long lifetime.
