Studies On The Supramolecules Properties Of The IHqs-Metal Luminescent Complexes Incorperating Cucurbituril

Thyroid gland plays a key role in vertebrate’s life cycle. Iodine, Synthesized and produced by thyroid hormones, is the most important thyroid element among all the elements organism needed. In electric charge in-out transmit and Synthesis process, Iodine’s organisms active ability has drawn the attention of social sectors.CBn (Cucurbituril) is a kind of high symmetrical, large organic ring molecule. In the solution of ternary metal ion complex, CBn, as the substrate of object, face with the metal ion directly. Deep research of CBn heterozygous supramolecular complexes is used in Subject-object chemistry and supramolecular structure combination.The thesis made a contrast with the two new CB6-relevant supramolecular:the crystal structure of [Zn(HQS)2][Na2(CB6)(H2O)8] and [Zn(HQS)2]2[K4(CB6)3(H2O)6].because of different coordinate model of alkali metal sodium, potassium and CB6led to Zn(HQS)2metal complexes taken respectively trans plane configurations and type folding configuration, made the structure of complexes1,2present different novel supramolecular characteristics.The thesis made a research on coordination system solution of ultraviolet spectral properties of the IHQSand HQS of Zn(Ⅱ), Mg (Ⅱ), or Al (Ⅲ) when CB6and CB7existed, discussed CB6and CB7’s influence on the complexes of charge of the migration of the spectrum through making a comparative study with the not contain CB large ring system, and discussed the influence law of iodine through the comparison of not containing iodine and containing iodine system.With the study of fluorescence spectrometry on the above system complexes solution shine study found that the participation of CB6and CB7enhanced the fluorescence intensity of ligands and found that different large ring resulted in different fluorescence intensity. The thesis respectively discussed possible solution supramolecular role model of iodine and large ring to CB fluorescent complexes.The thesis made a research on competitive recognition Of complexes system of Mg (Ⅱ) and Al (Ⅲ) through putting in different amount Al (Ⅲ)to complexes system of Mg (Ⅱ)2HQS or2IHQS making its and Mg (Ⅱ) competition ligands coordinative until full replacement Mg (Ⅱ) ions going out. Through the spectrum comparative analysis, the thesis discussed the replacement ion Mg (Ⅱ)’s influence on the complexes ultraviolet spectrum and the nature of light inferring its pathogenesis mechanism, and discussed the structure of large ring iodine and effect.The results of this thesis explored chemistry research of the organic large ring of CBn supramolecular and showed applicable prospect of CBn in luminous function.
