帮忙翻译一段荧光红移蓝移比较的句子
|
||
| 氨基取代在苯环上的化合物4a,4b,4c与相应的未取代物3a,3b,3c比较，最大发射波长分别红移了5nm,7m,9nm.而氨基取代在噻吩环上的化合物4g,4h,4i与相应的未取代物3g,3h,3i比较最大发射波长分别蓝移了4nm,7nm,8nm，另一方面吸电子的氰基取代在噻吩环上的化合物4j,4k与相应的未取代物3j,3k比较最大发射波长分别红移了15nm,25nm. |

| 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. |
