Construction of light-responsive phase chirality from an achiral macrogelator
To realize light-responsive phase chirality from an achiral macrogelator in the solid state, a disc-shaped achiral macrogelator (B1AZ) was newly synthesized. B1AZ was self-assembled into a lamello-columnar structure in the bulk state, while single-handed helical fibrils ( H F ) with 400 nm of helica...

| description | To realize light-responsive phase chirality from an achiral macrogelator in the solid state, a disc-shaped achiral macrogelator (B1AZ) was newly synthesized. B1AZ was self-assembled into a lamello-columnar structure in the bulk state, while single-handed helical fibrils (
H
F
) with 400 nm of helical pitch were constructed by side-by-side lateral association of achiral B1AZ molecules in carvone chiral solvents. Even after the elimination of chiral solvents, the helical morphology and its chiroptical properties were precisely preserved. However,
H
F
was not sensitive to UV light due to intense lateral packing. For remote-controlling the helical morphology, a single-helix (
H
S
) with an 18 nm helical pitch was formed by utilizing
cis
-B1AZ sol. Upon irradiation with UV light,
H
S
was transformed into spheroids (
S
) because of the
trans
-to-
cis
photo-isomerization of the azobenzene (AZ) of B1AZ. The photo-switchable phase chirality can be applied in light-responsive smart materials.
Phase chirality constructed from a light-responsive achiral macrogelator in a chiral solvent was remote-controlled by UV light. |
