Graphical Abstract

Multicolored structured liquids were prepared by tuning the aggregation of porphyrin. J- and H-aggregates of H4TPPS2− and H-aggregates of H2TPPS4− were formed by the electrostatic interaction between H4TPPS2− and polymer ligands.

Abstract

Locking nonequilibrium shapes of liquids into targeted architectures by interfacial jamming of nanoparticles is an emerging area in material science. 5,10,15,20-tetrakis(4-sulfonatophenyl) porphyrin (H6TPPS) shows three different aggregation states that present an absorption imaging platform to monitor the assembly and jamming of supramolecular polymer surfactants (SPSs) at the liquid/liquid interface. The interfacial interconversion of H6TPPS, specifically H4TPPS2− dissolved in water, from J- to an H-aggregation was induced by strong electrostatic interactions with amine-terminated polystyrene dissolved in toluene at the water/toluene interface. This resulted in color-tunable liquids due to interfacial jamming of the SPSs formed between H4TPPS2− and amine-terminated polystyrene. However, the formed SPSs cannot lock in nonequilibrium shapes of liquids. In addition, a self-wrinkling behavior was observed when amphiphilic triblock copolymers of PS-block-poly(2-vinylpyridine)-block-poly(ethylene oxide) were used to interact with H4TPPS2−. Subsequently, the SPSs formed can lock in nonequilibrium shapes of liquids.
