Synthesis and solution behaviour of metal-carbonyl amphiphiles with an Fp (CpFe(CO)2) junction
Metallo-amphiphilic macromolecules with an iron-carbonyl junction (PEGPPh2-FpR, PEGPPh2: polyethylene glycol diphenyl phosphine, Mn, PEG = 550 or 2000 g/mol; R = octadecyl or hexyl; Fp = CpFe(CO)2) are synthesized via migration insertion reaction of FpR in the presence of PEGPPh2 and are characteriz...

The prepared amphiphiles are air stable, soluble in most organic solvents, e.g. THF, DCM, DMF, and exhibit a reversible redox activity as indicated by cyclic voltammetry (CV) experiments. Surface tension measurements indicate that the prepared molecules exhibit typical amphiphilic properties with critical micelle concentrations (CMC) in water ranging between 30 and 113 μM. The aqueous micelles aggregated from PEGPPh2-FpR agglomerate into suspensions, which is similar with the solution behaviour of Brij® surfactants, the organic analogue without the Fp junction. The redox activity of Fp junction in 1–4, which is sensitive to assembling structures, will be a possible advantage for further investigation on this agglomeration behaviour. | ||

Synthesis and solution behaviour of metal-carbonyl amphiphiles with an Fp (CpFe(CO)2) junction |
abstract |
Metallo-amphiphilic macromolecules with an iron-carbonyl junction (PEGPPh2-FpR, PEGPPh2: polyethylene glycol diphenyl phosphine, Mn, PEG = 550 or 2000 g/mol; R = octadecyl or hexyl; Fp = CpFe(CO)2) are synthesized via migration insertion reaction of FpR in the presence of PEGPPh2 and are characterized using 31P, 1H NMR and IR. The prepared amphiphiles are air stable, soluble in most organic solvents, e.g. THF, DCM, DMF, and exhibit a reversible redox activity as indicated by cyclic voltammetry (CV) experiments. Surface tension measurements indicate that the prepared molecules exhibit typical amphiphilic properties with critical micelle concentrations (CMC) in water ranging between 30 and 113 μM. The aqueous micelles aggregated from PEGPPh2-FpR agglomerate into suspensions, which is similar with the solution behaviour of Brij® surfactants, the organic analogue without the Fp junction. The redox activity of Fp junction in 1–4, which is sensitive to assembling structures, will be a possible advantage for further investigation on this agglomeration behaviour. |

Surface tension measurements indicate that the prepared molecules exhibit typical amphiphilic properties with critical micelle concentrations (CMC) in water ranging between 30 and 113 μM. The aqueous micelles aggregated from PEGPPh2-FpR agglomerate into suspensions, which is similar with the solution behaviour of Brij® surfactants, the organic analogue without the Fp junction. The redox activity of Fp junction in 1–4, which is sensitive to assembling structures, will be a possible advantage for further investigation on this agglomeration behaviour.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Migration insertion reaction</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Iron-phosphine amphiphiles</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Metal-carbonyl complex</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Iron-carbonyl PEG amphiphile</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Fp-surfactants</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Organometallic amphiphiles</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">El-Temtamy, Abdelrahman</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Xiaosong</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Li, Chenglong ELSEVIER</subfield><subfield code="t">The Effect of Simultaneous Renal Replacement Therapy on Extracorporeal Membrane Oxygenation Support for Postcardiotomy Patients with Cardiogenic Shock: A Pilot Randomized Controlled Trial</subfield><subfield code="d">2019</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV002971518</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:851</subfield><subfield code="g">year:2017</subfield><subfield code="g">day:15</subfield><subfield code="g">month:11</subfield><subfield code="g">pages:40-45</subfield><subfield code="g">extent:6</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.jorganchem.2017.09.003</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">44.85</subfield><subfield code="j">Kardiologie</subfield><subfield code="j">Angiologie</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">44.66</subfield><subfield code="j">Anästhesiologie</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">851</subfield><subfield code="j">2017</subfield><subfield code="b">15</subfield><subfield code="c">1115</subfield><subfield code="h">40-45</subfield><subfield code="g">6</subfield></datafield><datafield tag="953" ind1=" " ind2=" "><subfield code="2">045F</subfield><subfield code="a">540</subfield></datafield></record></collection>
