Photoluminescent Metal‐Organic Nanotubes via Hydrothermal in Situ Ligand Reactions

“…The hydrothermal in situ condensations between o ‐phenylenediamine ( o ‐PD) and oxalic acid into benzimidazolyl derivatives in the presence of different metal ions have been reported recently 24. It was reported that the condensation reactions involving H 2 bbim ligand were pH dependent, which is similar to our results for the formation of H 2 bbim and HbimbdcH 2 in 1 – 3 (Scheme ).…”

“…The optimum pH value for the condensation of o ‐PD and 1,3,5‐benzene tricarboxylic acid to HbimbdcH 2 was 5 in the formation of 3 while a pH value of 4 was the optimum value for preparing complexes 1 and 2 since the highest yields could be obtained. No benzimidazole analogues could have been obtained in the previous report24 when using 1,4‐benzene dicarboxylic acid as an ancillary ligand or using other simple dicarboxylic acids taking the place of oxalic acid. Interestingly in our study, condensation can also be found between o ‐PD and 1,3,5‐benzene tricarboxylic acid and a new multidentate ligand, HbimbdcH 2 , was yielded.…”

1,4-Bis(1H-benzimidazol-2-yl)benzene methanol monosolvate

“…For the synthesis of the title compound see: Wu et al (2009). For the properties and applications of benzimidazoles, see: Tidwell et al (1993); Salunke et al (1994); Hoorn et al (1995); van Berkel et al (1995); Dinolfo et al (2005); Yang et al (2008). For structures of 1,4-bis(benzimidazol-2-yl)benzene analogues, see: Bei et al (2000); Wu et al (2009).…”

“…In earlier communications (Tidwell, et al, 1993;Salunke, et al, 1994;Hoorn, et al, 1995;van Berkel, et al, 1995;Dinolfo et al, 2005;Yang et al, 2008;) it has been reported that the benzimidazole moiety is an important heterocyclic ring not only because of its wide-ranging antivirus activity, its importance in selective ion-exchange resin, but also because of the interest in the coordination chemistry of azoles acting as ligands in transition metal compounds. However, the crystal structure of 1,4-bis(benzimidazol-2-yl)benzene analogues have rarely been reported (Bei, et al, 2000;Wu, et al, 2009;).…”

Exploring the Scope of Macrocyclic “Shoe-last” Templates in the Mechanochemical Synthesis of RHO Topology Zeolitic Imidazolate Frameworks (ZIFs)

“…[47]. Traditional solvothermal synthetic procedures have found that reaction of HBIm with tetrahedral metal ions gives only three ZIF topological outcomes in the absence of other co-ligands: the RHO topology RHO-ZnBIm 2 (ZIF-11), RHO-CoBIm 2 (ZIF-12) [2], the SOD topology SOD-ZnBIm 2 (ZIF-7) [2], SOD-CoBIm 2 (ZIF-9) [2], SOD-CdBIm 2 (CdIF-13) [48] or the layered, close-packed sql-ZnBIm 2 [49]. sql-ZnBIm 2 [42] and sql-CoBIm 2 [50] have also been prepared by mechanochemical synthesis, by aging of a ZnO/HBIm mixture with addition of (NH 4 ) 2 SO 4 in H 2 O vapors, and LAG of a Co(NO 3 ) 2 •6H 2 O/HBIm mixture with ethanol, respectively.…”
