| Outline of Final Research Achievements |
(1) We found that a dumbbell type pyridyl-cavitand and a dumbbell type phenol-cavitand with long flexible spacers self-assemble into a super-macrocyclic dimer (supramolecular giant ring) based on hydrogen-bonded hetero-capsule as a connector, without formation of a supramolecular polymer. (2) We found that a self-assembled boronic ester cavitand capsule encapsulates one molecule of BPEA derivatives as optical functional guests, which show greater resistance to photochemical reactions and enhancement of photophysical properties such as two-photon absorption, compared to free guests. We also found that this type of a chiral capsule induces supramolecular chirality with respect to a prochiral biphenyl guest by diastereomeric encapsulation. (3) We found the self-assembly of calix[4]resorcinarene bearing azobenzene-dendron conjugates as side chains into a hexameric capsule with photoresponsive properties that releases encapsulated guest molecule upon UV irradiation.
