摘要
To discover novel fluoro p hores of solution and solid dual-state emission(DSE) materials,unique V-shape furo[2,3-b]furans have been designed and synthesized by a one-pot method for the first time and their photoluminescent properties have been explored in benzene,THF,DMF and DMSO,as well as in the solid state.As the best example,2,5-bis(4-(9 H-carbazol-9-yl)phenyl)-6 a-amino-3 a,6 a-dihydrofuro[2,3-b]furan-3,3 a,4-trica rbonitrile(3 g) exhibited solution and solid DSE properties in THF,benzene,and in the solid state with quantum yields of 55%,92%,and 45%,respectively.
