| Abstract: | Three kinds of novel N-coumarin derivatives with thiophene asπbridge,named 7-N,Ndiethylamino-3-(5-pyren-1-yl-thiophen-2-yl)-coumarin(Py-Th-NC),7-(N,N-diethylamino)-3-(4-(5-(7-(N,Ndiethylamino)-coumarin-3-yl)thiophen-2-yl)phenyl)-coumarin(NC-Th-Ph-NC)and 3-(4-(5-(7-(N,Ndiethylamino)-coumarin-3-yl)thiophen-2-yl)phenyl)-coumarin(NC-Th-Ph-C),were successfully synthesized.Their structures were confirmed by HRMS,1 H NMR and IR.The luminescence properties,electrochemical properties and thermal stabilities of these compounds were investigated.The results revealed that they exhibit good thermal stabilities and show strong blue-green or green photoluminescence in dichloromethane solution. |
