Self-assembly and optical properties of a porphyrin-based amphiphile.
نویسندگان
چکیده
A porphyrin-based amphiphile that exhibits various self-assembled nanostructures in different solvents has been successfully prepared. The effect of aggregated structure on optical properties of this amphiphile has been well investigated. Furthermore, this porphyrin-based amphiphile and its assemblies show dynamic/reversible variations in morphology and optical properties in response to light.

Coarse-grained simulation of amphiphilic self-assembly.
The authors present a computer simulation study of amphiphilic self-assembly performed using a computationally efficient single-site model based on Gay-Berne [J. Chem. Phys. 74, 3316 (1981)] and Lennard-Jones particles. Molecular dynamics simulations of these systems show that free self-assembly of micellar, bilayer, and inverse micelle arrangements can be readily achieved for a single model pa...

متن کاملLDRD Final Report on Adaptive- Responsive Nanostructures for Sensing Applications
Functional organic nanostructures such as well-formed tubes or fibers that can easily be fabricated into electronic and photonic devices are needed in many applications. Especially desirable from a national security standpoint are nanostructures that have enhanced sensitivity for the detection of chemicals and biological (CB) agents and other environmental stimuli. We recently discovered the fi...
متن کاملInterfiber interactions alter the stiffness of gels formed by supramolecular self-assembled nanofibers†
Molecular self-assembly is a powerful technique for developing novel nanostructures by using noncovalent interactions such as hydrogen bonding, hydrophobic, electrostatic, metal–ligand, p–p and van der Waals interactions. These interactions are highly dynamic and are often delicate due to their relatively weak nature. However, a sufficient number of these weak interactions can yield a stable as...
