To discover novel fluorophores 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-(9H-carbazol-9-yl)phenyl)-6a-amino-3a,6a-dihydrofuro[2,3-b] furan-3,3a,4-tricarbonitrile (3g) exhibited solution and solid DSE properties in THF, benzene, and in the solid state with quantum yields of 55%, 92%, and 45%, respectively.
