| 520 | |a (11-((Adamantane-1-carbonyl) oxy)-N,N-dimethylundecan-1-benzylammonium bromide (C11AD), a novel cationic surfactant containing an adamantane group and a hydrophobic chain, had been synthesized. Experiments were carried out to understand aggregate morphology transition via the host-guest interaction with β-cyclodextrin. Two groups of inclusion complexes were prepared by mixing C11AD and β-cyclodextrin (β-CD) in aqueous solution with 1:1 or 1:2 stoichiometry, denoted as C11AD/nβ-CD (n = 1 or 2). Results showed that C11AD could self-assemble into spherical-like micelles in aqueous solution, and the micelles of C11AD transformed into spherical vesicles, straight nanotubes or networks hydrogels with β-CD in different stoichiometries. The aggregation behaviors of surfactant C11AD by the host-guest interaction with β-cyclodextrin (β-CD) were investigated by transmission electron microscopy (TEM), Cryogenic Transmission electron microscopy (Cryo-TEM), scanning electron microscopy (SEM) and dynamic light scattering (DLS) measurement. A possible mechanism to explain aggregate transitions was suggested by the results of FT-IR, 1H NMR and 1H-1H 2D ROESY NMR spectra. Data reflected that β-CD first combined with the adamantane group in C11AD/1β-CD system to form spherical vesicles. Then increasing the β-CD amount, superfluous cyclodextrin would combine with the hydrophobic chain in C11AD/2β-CD system. Thus the hydrophobic interaction was destroyed and the hydrogen bonds, the main driving force, were the prime mover in the process of nanotubes and hydrogels formation. | ||

Two groups of inclusion complexes were prepared by mixing C11AD and β-cyclodextrin (β-CD) in aqueous solution with 1:1 or 1:2 stoichiometry, denoted as C11AD/nβ-CD (n = 1 or 2). Results showed that C11AD could self-assemble into spherical-like micelles in aqueous solution, and the micelles of C11AD transformed into spherical vesicles, straight nanotubes or networks hydrogels with β-CD in different stoichiometries. The aggregation behaviors of surfactant C11AD by the host-guest interaction with β-cyclodextrin (β-CD) were investigated by transmission electron microscopy (TEM), Cryogenic Transmission electron microscopy (Cryo-TEM), scanning electron microscopy (SEM) and dynamic light scattering (DLS) measurement. A possible mechanism to explain aggregate transitions was suggested by the results of FT-IR, 1H NMR and 1H-1H 2D ROESY NMR spectra. Data reflected that β-CD first combined with the adamantane group in C11AD/1β-CD system to form spherical vesicles. Then increasing the β-CD amount, superfluous cyclodextrin would combine with the hydrophobic chain in C11AD/2β-CD system. Thus the hydrophobic interaction was destroyed and the hydrogen bonds, the main driving force, were the prime mover in the process of nanotubes and hydrogels formation.

Data reflected that β-CD first combined with the adamantane group in C11AD/1β-CD system to form spherical vesicles. Then increasing the β-CD amount, superfluous cyclodextrin would combine with the hydrophobic chain in C11AD/2β-CD system. Thus the hydrophobic interaction was destroyed and the hydrogen bonds, the main driving force, were the prime mover in the process of nanotubes and hydrogels formation.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hu, Caixia</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yan, Xiaowei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Xing</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhu, Dongjian</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">Moreno-Cabezali, Belen Maria ELSEVIER</subfield><subfield code="t">Application of a fuzzy-logic based model for risk assessment in additive manufacturing R&D projects</subfield><subfield code="d">2020</subfield><subfield code="d">an international journal devoted to fundamental aspects of structure, interactions and dynamic processes in simple, molecular and complex liquids</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV004280490</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:272</subfield><subfield code="g">year:2018</subfield><subfield code="g">day:15</subfield><subfield code="g">month:12</subfield><subfield code="g">pages:209-217</subfield><subfield code="g">extent:9</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.molliq.2018.09.096</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="936" ind1="b" ind2="k"><subfield code="a">85.35</subfield><subfield code="j">Fertigung</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">54.80</subfield><subfield code="j">Angewandte Informatik</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">272</subfield><subfield code="j">2018</subfield><subfield code="b">15</subfield><subfield code="c">1215</subfield><subfield code="h">209-217</subfield><subfield code="g">9</subfield></datafield></record></collection>
