| In comparission to unsubstituted compounds 3a,3b and 3c, maximum emission wavelengths of the amino substituted in the benzene ring compounds 4a, 4b, 4c have a red-shift of 5nm, 7nm and 9nm, while the same subtituted group on thiophene ring, compounds 4g, 4h and 4i have a blue-shift of 4nm,7nm and 8nm compared to those of unsubstituted compounds 3g,3h and 3i. In rhe other hand, when cyano substituted on thiophene ring, which is one type of the abstracted electron groups, the compounds of 3j and 3k have the maximum emission wavelength red-shift of 15nm and 25nm than those of compunds of 3j and 3k, respectively. |

| Amino substituted in the benzene ring compounds 4a, 4b, 4c and the corresponding object is not to replace the 3a, 3b, 3c comparison, the maximum emission wavelengths are red-shift of 5nm, 7m, 9nm. While the amino substituted in the thiophene ring of compounds 4g, 4h, 4i and the corresponding object is not to replace the 3g, 3h, 3i compare the maximum emission wavelengths are blue-shifted 4nm, 7nm, 8nm, the other hand, the cyano electron withdrawing replace the thiophene ring of compounds 4j, 4k and the corresponding outstanding to replace the material 3j, 3k, respectively compare the maximum emission wavelength red-shift of 15nm, 25nm. |
