Monolayer nanotubes self‐assembled from amphiphilic molecules are able to encapsulate dinucleotides via electrostatic attraction. In article number 1801967 , Naohiro Kameta and Haruhisa Akiyama discover that upon photoirradiation, the 18‐nm inner diameter of the nanotubes shrink to less than 2 nm as a result of photochemical cleavage of the 2‐nitrobenzyl groups in the amphiphiles. This shrinking leads to a propulsive release of the dinucleotides into the bulk solution and simultaneously accelerates the formation of the dinucleotide duplexes.
