Material properties and applications of mechanically interlocked polymers

Weakly acidic carboxy group-grafted β-cyclodextrin-threaded acid-degradable polyrotaxanes for modulating protein interaction and cellular internalization

“…Cyclodextrin (CD)-threaded polyrotaxane (PRX) is a representative supramolecular polymer, in which several CDs are threaded along a linear polymer chain and interlocked onto the polymer axis through capping with bulky stopper molecules [1][2][3]. PRXs have recently received considerable attention as a new class of polymeric materials because the molecular mobility of threaded cyclic molecules imparts new material functions [4]. Another advantage of PRXs for material applications is their stimuli-responsive dissociative character [5,6].…”

Effect of metallosupramolecular polymer concentration on the synthesis of poly[n]catenanes

“…6 As more efficient synthetic methods have been developed to access interlocked molecules, there has been a corresponding growth of activity into mechanically interlocked polymers (MIPs). [7][8][9][10] These new polymeric materials exhibit unusual property proles, 11 that include increased stress dissipation and high extensibility. [12][13][14] One of the more intriguing MIP architectures is the poly[n]catenane-a polymer chain that is entirely comprised of interlocked macrocycles where the number of mechanical bonds is optimized (Fig.…”

Temperature‐Triggered Structural Dynamics of Non‐Coordinating Guest Moieties in a Fluorescent Actinide Polyrotaxane Framework

“…The obtained 1D architecture can be identified as a main‐chain coordination polyrotaxane. According to Rowan et al., [10] main‐chain polyrotaxanes are those the backbone is part of the rotaxane moiety, either as the string or the host component. It's worthy to note that, C7BPy without any functional groups does not participate in metal coordination.…”
