| Abstract |
A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide rotaxanes. The present paper discusses the synthesis and the structural and dynamic characterizations of the first examples of anionic boron cluster-containing rotaxanes. To study the dynamic properties of such molecules, the pirouetting rate of the weakly coordinating boron cluster-containing rotaxanes with the more strongly coordinating trifluoroacetate anion (TFA(-)), which would form a close ion pair with the macrocycle, was measured using the exchange spectroscopy NMR technique. Our hypothesis was that the stronger the ion pair the lower the rate of rotation due to the presence of a bigger volume of solvent to be moved. The anion would act as an anchor for the pirouetting motion. Indeed, the results show the expected trend: the rotaxane with the closely coordinating TFA(-) anion pirouettes most slowly, and the most weakly coordinating hexabromoderivative of cobaltabisdicarbollide pirouettes the fastest. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 July 2014.
All research outputs
#14,782,907
of 22,758,963 outputs
Outputs from Inorganic Chemistry
#12,409
of 21,601 outputs
Outputs of similar age
#125,917
of 228,769 outputs
Outputs of similar age from Inorganic Chemistry
#208
of 392 outputs
Altmetric has tracked 22,758,963 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 21,601 research outputs from this source. They receive a mean Attention Score of 2.8. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 228,769 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 392 others from the same source and published within six weeks on either side of this one. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
