Abstract
Recently, we have reported the self-assembly of two molecules of cavitand tetraboronic acid and four molecules of 1,2-bis(3,4-dihydroxyphenyl)ethane into a capsule via dynamic boronic ester bond formation. Here, we describe recent topics of the boronic ester capsule: (1) the use of the capsule as a guard nanocontainer to protect against photochemical reactions of anthracene derivatives as guests, (2) tunable capsule space by the self-assembly of the cavitand tetraboronic acid with various types of bis(catechol)-linkers, and (3) the linker exchange reaction between two types of capsules.
