| 中文摘要 | Fluorescent whitener (4,4 '-bis(2-sulfonatostiryl)biphenyl) was incorporated with M/4,4 '-bipy (M = Cd, Cc; 4,4 '-bipy=4,4 '-bipyridine) 2D frameworks, Mn/4,4 '-bipyH fragment, and the [Zn-2(Im)(2)(ImH)(4)](2+) (ImH = imidazole) chain under hydrothermal conditions to obtain seven new coordination polymers: [Cd(4,4 '-bipy)(L)(H2O)(2)] (1), (Co(4,4 '-bipy)(2)(L)]center dot 2H(2)O (2), [Co(4,4 '-bipy)(2)(H2O)(2)](4,4 '-bipy)(L)center dot 2H(2)O (3), [Mn(4,4 '-bipyH)(2)(L)(2)(H2O)(2)]-4H(2)O (4), and [Zn-2(Im)(2)(ImH)(4)](L) (5). Their structures were determined by single-crystal X-ray diffraction. In 1, binuclear [Cd-2] units are bridged by 4,4 '-bipys into a 2D cationic framework, which is further penetrated by L anions. 2 has an organic-inorganic hybrid layer consisting of [Co(4,4 '-bipy)(2)] squarelike motifs and L anions. 3 features a pcu-like 3D cationic framework with the inclusion of L anions. In 4, the [Mn(4,4 '-bipyH)(2)(H2O)(2)](4+) cationic fragment is sandwiched by L anions into a sandwichlike hybrid layer. 5 exhibits a 3D honeycomb-like structure with each nanotube encapsulating two parallel L anionic chains. TGA and PXRD indicate solids 1, 4, and 5 are thermally stable up to 280, 200, and 250 degrees C under an air atmosphere, respectively. 1 has bright blue-green luminescence with a peak maximum band at about 470 nm. 4 exhibits tunable emission between dark-red and weak-green under the excitation of 500 and 280 nm, respectively. 5 displays a bright blue-green emission with a peak band at 454 nm and a shoulder peak at 473 nm. It is attractive that the luminescent properties of solids 1, 4, and 5 are almost retained after heat treatment at 200, 200, and 250 degrees C for 2 h under an air atmosphere, respectively. |
