Spontaneous self-assembly of water-soluble porphyrins having poly(ethylene glycol) as branches: Dependence of aggregate properties from the building block architecture

► Aggregates by spontaneous self-assembly of uncharged water-soluble porphyrins. ► H- or J-type aggregate structure as a function of the PEG position in the porphyrins. ► Light depolarization as a consequence of the different molecular architectures. ► Porphyrins self-assembled for applications in material science and nanotechnology.
