a Structure of zinc(II)−2,3,9,10,16,17,23,24-octa(4-carboxyphenyl)phthalocyanine (ZnOPPc) (b) Transmission electron microscopy (TEM) images of the framework of aggregates, scale bar is 20 nm (c) Absorption spectra of ZnOPPc monomer (in DMSO), H-aggregate (in aq. NaOH) and HOF (connected aggregates, in neutral H2O) with the laser spectrum used for two-dimensional electronic spectroscopy (2DES) and fluence-dependent pump-probe experiments (d) Atomic force microscopy (AFM) profile distributions for several HOF particles, scale bar is 1 micron. Source data are provided as a source data file.
