An organic–inorganic hybrid uranyl nicotinate molybdate polymer and its fluorescent property

[Hg5O2(OH)4][(UO2)2(AsO4)2]: A complex mercury(II) uranyl arsenate

“…Fluorescence from uranyl compounds can be identified from the vibronic fine-structure characteristic of the UO 2þ 2 moiety [34]. Uranyl fluorescence typically has a characteristic five peak spectrum relating to the S 11 -S 00 and S 10 -S 0n (n ¼ 0-4) electronic and vibronic transitions, and for UO 2 (NO 3 ) 2 Á 6H 2 O the most intense peak (S 10 -S 00 ) is position at 508 nm [35][36][37]. The vibronic transitions for HgUAs-1 are somewhat broad, and five transitions are discernable, as shown in Fig.…”

Supramolecular chemistry with uranyl tetrahalide ([UO2X4]2−) anions

“…As a rich body of uranyl coordination polymers currently exists [11][12][13][14][24][25][26][27][28][29][30][31][32][33], and considering the success of this 'non-covalent' approach [20], we embarked on further exploration of these supramolecular-based polymeric compounds. In this contribution, we explore a new tecton, namely uranyl tetrabromide ([UO 2 Br 4 ] 2À ), a moiety previously observed in the solid state (yet not in this context) [34,35], to demonstrate the utility of supramolecular chemistry when creating families of uranyl materials.…”

Investigation on the Synthesis and Photocatalytic Property of Uranyl Complexes of the β-Diketonates Biscatecholamide Ligand

“…were assigned to the C=O stretching vibration of amide groups of free ligands, which shifted to 1588 cm −1 in its corresponding complexes; meanwhile, the peaks at 1266 cm were assigned to the asymmetric stretching modes of the uranyl moiety [25][26][27]. Therefore, analytical results of the International Journal of Photoenergy FTIR spectra indicated uranyl ion complexes were to be obtained.…”
