Electric Literature of C19H18BrPThis research focused onuranyl adamantanediacetate adamantanedicarboxylate coordination polymer preparation crystal structure; photoluminescence luminescence uranyl adamantanediacetate adamantanedicarboxylate coordination polymer. The article conveys some information:
Seven homo- or heterometallic uranyl ion complexes with 1,3-adamantanedicarboxylic acid (H2ADC) or 1,3-adamantanediacetic acid (H2ADA) have been synthesized under solvo-hydrothermal conditions in the presence of different counterions and organic cosolvents, and characterized by their crystal structure and uranyl emission spectrum. [PPh3Me][UO2(ADC)(NO3)] (1) crystallizes as a simple monoperiodic chain, but [PPh4]2[(UO2)2(ADC)3]·2H2O (2) and [PPh4]2[(UO2)2(ADA)3] (3) display trough-like monoperiodic polymers (assembled in pairs in 3) in the cavity of which the counterions are located. A similar arrangement is found in [Ni(cyclen)(H2O)][(UO2)2(ADC)3]·H2O (4). Diaxial bonding of NiII in [(UO2)2(ADC)2Ni(R,S-Me6cyclam)(HCOO)2]·CH3CN (5) and [UO2(ADA)2Ni(R,S-Me6cyclam)] (6) results in bridging monoperiodic uranyl-containing subunits into neutral, diperiodic networks. [UO2(ADA)(DMPU)] (7), containing coordinated N,N’-dimethylpropyleneurea, is also a diperiodic assembly with the common fes topol. type. Except complex 6 which is non-luminescent, all complexes give solid-state emission spectra displaying the usual vibronic fine structure, albeit with low photoluminescence quantum yields. In the experiment, the researchers used many compounds, for example, Methyltriphenylphosphonium bromide(cas: 1779-49-3Electric Literature of C19H18BrP)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.Electric Literature of C19H18BrP
