A method of making a multilayered chromonic structure comprises (a)
preparing a first aqueous mixture comprising (i) a first continuous
water-soluble polymer phase and (ii) a first discontinuous chromonic
phase comprising a chromonic material, to form chromonic
nanoparticles;(b) non-covalently crosslinking the resulting chromonic
nanoparticles with a multivalent cation salt; (c) dispersing the
resulting crosslinked chromonic nanoparticles in a composition comprising
a chromonic material to form a chromonic nanoparticle dispersion; and (d)
preparing a second aqueous mixture comprising (i) a second discontinuous
chromonic phase comprising the chromonic nanoparticle dispersion and (ii)
a second continuous water-soluble polymer phase, to encapsulate the
chromonic nanoparticles; wherein at least one of the first discontinuous
chromonic phase and the second discontinuous chromonic phase further
comprises a guest compound.
