An answer to the SPIRO versus ANSA dilemma in cyclophosphazenes. Part XVI. Synthesis and crystal structure of the first SPIRO species from dithiadiamines

Aminolysis of hexachlorocyclotriphosphazene, N3P3Cl6, by dithiadiamines in suitable conditions yields mono-SPIRO species which constitute new macrocyclic monocyclophosphazenic structures containing sulphur atoms in their loops.Such (S,S) compounds are isologous to previously described oxygenated cyclophosphazenic cages which are commonly capable of inclusion of "hard" metals.Thus, one may expect that (S,S) cages will be useful for inclusion of "soft" metals.The X-ray structure of the (S,S) mono-SPIRO derivative from 3,7-dithianonane-1,9-diamine (coded as SS232) reveals two crystallographically independent molecules in the unit cell, and also shows the conformations of SPIRO loops.

The turn-off fluorescent sensors based on thioether-linked bisbenzamide for Fe3+ and Hg2+

Some dibenzamide derivatives with a thioether linker were designed, synthesized and characterized. The specific responses to Hg2+ and Fe3+ were investigated by fluorescence. According to fluorescence titration, the Job plot, 1H NMR, and ESI-mass analysis, the derivative with mono-hydroxyl substituent (1b) on the aromatic ring has high selectivity for Fe3+ ion with the formation of 1:1 1b-Fe3+ complexes. The specificity of 1c for Hg2+ could be switched by swapping the substituent from hydroxyl to amino, and a 1:2 (1c-Hg2+) complex was formed. Along with the obtained results, density functional theory (DFT) and natural bond orbital (NBO) analyses, Time-dependent (TD) DFT and natural transition orbital (NTO) analyses were employed to explore the geometric structures, properties and possible mechanisms.
