Abstract:
A bidentate ligand, 1‐{4‐[4‐(1 H ‐1,2,4‐triazol‐1‐yl)phenoxy]phenyl}‐1 H ‐1,2,4‐triazole (TPPT), has been designed and synthesized. By using TPPT as a building block for self‐assembly with Cd(NO 3 ) 2 ⋅ 4 H 2 O and CdCl 2 ⋅ 10.5 H 2 O, novel 1D double‐chain {[Cd(TPPT)(NO 3 ) 2 ] ⋅ 3 H 2 O} n ( 1 ) and 2D (4,4) layer [Cd(TPPT)Cl 2 (H 2 O)] n ( 2 ) have been constructed. When 1 was employed as a precursor and exposed to DMF or N , N ′‐dimethylacetamide (DMAC), the crystals of 1 dissolved and reassembled into two types of brown block‐shaped crystals of 1D double chains: {[Cd(TPPT) 2 (NO 3 ) 2 ] ⋅ DMF} n ( 1 a ) and {[Cd(TPPT) 2 (NO 3 ) 2 ] ⋅ DMAC} n ( 1 b ). The anion‐exchange reactions of complex 2 have also been investigated. After gently stirring crystals of 2 in CHCl 3 /C 2 H 5 OH/H 2 O containing NaBr, NaI ⋅ 2 H 2 O, or NaOAc ⋅ 3 H 2 O, the crystals retained their crystalline appearances. A remarkable single crystal to single crystal transformation was observed and 1D double chains of {[Cd(TPPT)Br 2 ] ⋅ C 2 H 5 OH} n ( 2 a ) and {[Cd(TPPT) 2 I 2 ] ⋅ CHCl 3 } n ( 2 b ), and 1D single chains of [Cd(TPPT)(H 2 O) 2 (CH 3 COO) 2 ] n ( 2 c ), can be obtained. Luminescent properties indicate that 1 shows excellent selectivity for Ca 2+ and cyano complexes. To the best of our knowledge, this is the first example of a luminescent probe for Ca 2+ based on triazole derivatives.
