Abstract UV–Visible Reflection–Absorption Spectroscopy (UVRAS) technique is reviewed
with a general perspective on fundamental and applications. UVRAS is formally identical to …

Cationic porphyrins are under study in a number of contexts including their interaction with
biological targets, as possible therapeutic agents and as building blocks for molecular …

Two asymmetrically substituted porphyrins (5, 15-bis (4-nitrophenyl)-10, 20-bis (3, 4-bis (2-
ethylhexyloxy) phenyl)-21 H, 23 H-porphine, CAH3; 5, 15-bis (4-aminophenyl)-10, 20-bis (3 …

In this work, we have used thin films of the multiporphyrin, 1, 3-di [5-(3-hydroxyphenyl)-10,
15, 20-(triphenyl) porphyrin]-2-(5-(3-hydroxy-phenyl)-10, 15, 20-(triphenyl) porphyrin)-2 …

New water-soluble cationic meso-tetraarylporphyrins (TArP, Ar= 4-C6H4) and some metal
derivatives have been synthesized and characterized. One main goal was to assess if N …

Asphaltenes extracted from Arabian light crude oil have been investigated at the air− water
interface of a Langmuir trough by in situ optical techniques. Brewster angle microscopy …

The synthesis and characterization of bare silica (4 nm in diameter) nanoparticle-attached
meso-tetra (N-methyl-4-pyridyl) porphine (SiO2–TMPyP, 6 nm in diameter) are described for …

The orientation and aggregation of various porphyrin derivatives at the air–water interface
and in Langmuir–Blodgett films were investigated. Monolayer properties of these molecules …

Dual probe porphyrin-gold nanorod polyelectrolyte microcapsules were developed to
explore the enhancing effects of a plasmonic interface of self-assembled gold nanoparticles …

Surface plasmon resonance (SPR) spectroscopy and atomic force microscopy (AFM) have
been employed to investigate ferritin adsorption to binary surfactant monolayers of cationic …
