Figures

Image of FIG. 1.
FIG. 1.

(a) The molecular structure of MTC, (b) the absorption spectra of MTC in different states: (1) monomers, (2) H1-aggregates, (3) H2-aggregates, (4) J1-aggregates, and (5) J2-aggregates, and (c) the sample colors corresponding to above monomer and aggregates.

Image of FIG. 2.
FIG. 2.

The schematic illustration of the cycling transition from J1-aggregate to reverted J1-aggregate of MTC with the presence of 15 mM KCl in tris-HCl buffer (pH 7.0). The conversions of MTC aggregate from J1 to H2, H2 to J2, J2 to H2, and H2 to J1 with increasing amount of or EDTA were orderly exhibited in the absorption spectra a–d.

Image of FIG. 3.
FIG. 3.

The LCSM images of (a) J1-aggregate, (b) J2-aggregate, (c) reverted J1-aggregate, and (d) MTC monomer excited at 559 nm.
