Naphthalenedisulfonate-based Cd(II) CPs as fluorescent sensors for turn-on and red-shift sensing of tryptophan
Tryptophan (Trp) is one of the essential amino acids in human body, which is important for human health. Therefore, convenient strategies for the detection of Trp are very significant. Coordination polymers (CPs) have presented great importance as fluorescent sensors in recent years. Herein, two Cd(II) CPs were synthesized as fluorescent sensors for turn-on and red-shift sensing of tryptophan, namely, {[Cd(1,4-bbix)2(1,5-NDS)]·(H2O)2}n (1) and {[Cd(bmbp)2(H2O)2]·(1,5NDS)(H2O)4}n (2), (1,5-NDS = 1,5-naphthalenedisulfonate, 1,4-bbix = 1,4-bis(benzimidazol-1-yl-methyl)benzene, bmbp = 4,4′-bis(2-methylimidazole-1-yl-methyl)biphenyl). 1 shows a three-dimensional (3D) structure with 6-connected pcu topology. 2 shows a 1D chain, which is connected by hydrogen-bonds to form the 3D supramolecular structure. Both CPs can effectively detect Trp via fluorescence enhancement and red-shift in aqueous solution with the limits of detection being 1.11 μM and 0.69 μM for 1 and 2, respectively. Two CPs also can be applied for the detection of Trp in milk with good sensitivity. The sensing mechanisms toward Trp were investigated via experimental and theoretical calculation methods. The test films were prepared for the visual detection of Trp.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
