The bisazo dye Ponceau SS forms an acute oblique (V-type) dimer in dilute aqueous solution. In concentrated aqueous solution, these V-type dimers are considered to stack to form V-type blocks of chromonic liquid-crystalline (LC) columns. The weak int

To clarify the electronic spectral properties of uranyl(V) complexes systematically, we measured absorption spectra of three types of pure uranyl(V) complexes: [UVO2(dbm)2DMSO]-, [UVO2(saloph)DMSO]-, and [UVO2(CO3)3]5- (dbm = dibenzoylmethanate, salo
