increase with longer alkyl chains, but C2 is an exception to this
trend. Interestingly, when the alkoxyl chains surpass a certain
threshold, which appeared to be n ¼ 6 in this study, the smeared
powders did not revert to the ordered TA states under the
reported experimental conditions and on quartz substrates.
Additional structure-property studies, further characterization
and quantification of force induced effects, and mechanosensor
applications serve as topics for future work.
