The present work is focussed on the principles of photodynamic therapy (PDT), emphasizing
the photochemical mechanisms of reactive oxygen species formation and the consequent …

Chlorophyll molecules are well organized for efficient energy or electron transfer in a light-
harvesting antenna or a reaction center of photosynthetic organisms. In order to make …

The chirality of (nano) structures is paramount in many phenomena, including biological
processes, self-assembly, enantioselective reactions, and light or electron spin polarization …

The interactions of several water-soluble ionic porphyrins with different ionic or neutral
surfactants in aqueous solutions were studied as a function of surfactant concentration. The …

Catalyst design strategies such as bi-functional and di-nuclear catalysts have been
developed based on intramolecular interactions, achieving excellent catalytic performance …

Resonance light scattering (RLS) on supramolecular assemblies of chromophores is a
sensitive and selective method to extract size and shape information, but the interpretation of …

Tetrakis (4-sulfonatophenyl) porphine tetraanion (H2TPPS4-) forms a noncovalently linked
dimer at low concentration in aqueous solutions at pH 9.0 in the presence of potassium ion …

The aggregation behavior of protoporphyrin IX in aqueous solution, as a function of pH and
ionic strength, has been studied by means of UV/vis, fluorescence emission spectroscopy …

The spatial structure of the J-aggregates of meso-tetra (4-sulfonatophenyl) porphine
(TPPS4) formed in acidic aqueous solutions and coated on silicon substrates was analyzed …

Photochemical solar cells have been constructed from organized assemblies of single-
walled carbon nanotubes (SWCNT) and protonated porphyrin on nanostructured SnO2 …
