Lichtgesteuertes Schalten von Azobenzol‐Oligoglycerin‐Konjugaten auf supramolekular funktionalisierten Oberflächen

Abstract: Wir berichten über die Synthese, die Komplexierung und das Schalten in verschiedenen Umgebungen neuer difunktionaler Azobenzol-Oligoglycerin-Konjugate. Zunächst wurden die Schalter durch Wirt-Gast-Chemie an Goldoberflächen gekuppelt, und zwar über b-Cyclodextrin-Rezeptoren, die zuvor auf den entsprechenden Oberflächen immobilisiert worden waren, sowie eine Adamantylgruppe am Azobenzol. Das Isomerisierungsverhalten der amphiphilen Azobenzolderivate wurde in Lçsung, auf Goldnanopartikeln und auf planaren Goldobe… Show more

“…10 The light-driven interconversion between both isomers effectively changes their structure, 10 dipole, 11 and basicity, 12,13 which has driven the development of photoresponsive materials. [14][15][16] Research on azobenzene detergents has been focused on photoresponsive surface coatings, [17][18][19][20] catalysis systems, 21 and supramolecular aggregates. [22][23][24][25][26][27] The utility of anionic 4-hexylphenylazosulfonate for denaturing top-down proteomics has been outlined very recently.…”

“…Theability to control the hydrophilic/hydrophobic nature of as urface usually involves polymers, [38] self-assembled monolayers (SAM), [39] or surfaces with covalently attached responsive arrays. [40,41] Thehydrophobicity switching is important in micro-and nanotechnology, [42,43] for instance,i n chemical shielding, [44] self-cleaning surfaces, [45,46] and microfluidic applications. [47,48] In this respect, PPF PEG136,having ar elatively simple design and solution processing based on self-assembly,i sc apable of both reversible and irreversible changes,inducing hydrophilic/hydrophobics witching.…”
