Nanohoop Rotaxanes from Active Metal Template Syntheses and Their Potential in Sensing Applications

Abstract: The unique optoelectronic properties and smooth, rigid pores of macrocycles with radially oriented p systems render them fascinating candidates for the design of novel mechanically interlocked molecules with new properties.T wo high-yielding strategies are used to prepare nanohoop [2]rotaxanes,which owing to the p-rich macrocycle are highly emissive. Then, metal coordination, an intrinsic property afforded by the resulting mechanical bond, can lead to molecular shuttling as well as modulate the observed fluore… Show more

“…Two types of [2]rotaxanes based on small nanohoops featuring ortho ‐substituted pyridine moieties (Figure b, n =1, 3), were recently prepared by the Jasti group . The ortho substitution pattern alleviates much of the strain that would be present in the similarly sized nanohoops [6]CPP and [9]CPP and disrupts radial conjugation, which likely affects the photoluminescence of these macrocycles.…”

“…Zwei Arten von [2]Rotaxanen auf der Basis kleiner Nanoreifen mit zweifach ortho ‐substituierten Pyridinen (Abbildung b) wurden kürzlich von der Jasti‐Gruppe hergestellt . Das ortho ‐Substitutionsmuster verringert einen Großteil der Spannung, die bei ähnlich großen Nanoreifen [6]CPP und [9]CPP zu erwarten ist, und stört die radiale Konjugation, wodurch wahrscheinlich die Photolumineszenz dieser Makrozyklen beeinflusst wird.…”
