Kontrolle über Kettenvernetzung und Einzelkettenverknüpfung durch zwei Farben des sichtbaren Lichts

Abstract: Während photochemischeS ynthese den Zugang zu orts-und zeitaufgelçster Reaktionskontrolle ermçglicht, ist ihr Potential spezifische Reaktionen mit einer bestimmten Farbe des Lichts auszulçsen durcho mnipräsente spektrale Überlappe der reaktiven Gruppen limitiert. Nachfolgend wird ein neues Konzeptv orgestellt, das aktiv eine von zwei Ligationsreaktionen unterdrückt, indem die Cycloreversion der [2+ +2]-Cycloaddition des Styrylpyrens induziert wird.D ie Kombination dieser photoreversiblen Chemie und der [4+ +4]… Show more

“…The formation of nanosized compartments within such SCNPs has been intensely discussed, [1a, 6] proposing their use as functional units to generate microenvironments for catalysis, [7] photophysics, [8] or subsequent embedding of chiral elements [9] . As the formation of SCNPs is based on the collapse of single polymer chains at low concentration via covalent or non‐covalent intramolecular bonding interactions, [10] it “freezes‐in” the conformational state of the polymer chain into the final, crosslinked SCNP [11] . However, dynamics of the polymer chains often is at least partially preserved depending on the degree of crosslinking and solvent effects during the crosslinking process [6] .…”
