Fig. 3: Proposed membrane structure of THPG vesicles.

A representative HR-TEM image (a) and the magnified ones (b, c) of a single broken THPG vesicle. The inset in c is the fast Fourier transform (FFT) image of selected yellow square area in c. Similar HR-TEM images of THPG were observed for more than three separated samples. d Synchrotron SAXS of THPG vesicles. e The packing model of the porphyrin moieties in THPG vesicles from MD simulation. The red squares in e represent the ZnTHPP moieties. f A diagrammatic drawing of a THPG vesicle. g The magnified membrane cross-section. h The packing model of THPGs in the vesicle membrane.
