One measure that arctic fish and amphibians use to minimize damage to cellular membranes during cooling and freezing processes is the production of cryo-protective substances. We have mimicked this biological "trick" by using the surface of a cryo-pr

Experimental measurements of Mo6S4.5I4.5 nanowires investigating nonlinear optical extinction (NLE) of nanosecond laser pulses are reported. The experiments were performed using the open aperture Z-scan technique at 532 nm and 1064 nm. Concentration

The photophysical and nonlinear optical properties of a μ-oxo-bridged phthalocyanine heterodimer, i.e ., [ t Bu 4 PcGa-O-InPc t Bu 4 ] ( 5 ), where gallium is located in one macrocycle and indium is on the other macrocycle and the two metal atoms ar

The processing of one-dimensional nanomaterials, such as carbon-nanotubes, is generally hampered by the fact that they are insoluble. By conducting sedimentation experiments on Mo6S4.5I4.5 nanowires in isopropanol we show that a significant portion (

The use of guest-host systems, where phthalocyanines assume the role of guest inclusions in an otherwise homogeneous host polymer film, is a feasible method toward applying the phthalocyanine moiety in a solid-state passive optical limiter. In this c

A series of results from different photophysical experiments on indium and gallium phthalocyanine (Pc) compounds is reported. Gallium Pc's have much longer singlet and triplet excited state lifetimes in comparison with indium Pc's. The strong reverse

It is suspected that many of the physical properties observed in polymer–carbon nanotube composites are related to the formation of crystalline polymer coatings around the nanotubes. Here, a semi-conjugated polymer, poly(m-phenylenevinylene-co-2,5-

Single-wall carbon nanotubes are severely restricted by the fact that they exist in bundles. In addition, their interaction with other materials is poorly understood. In this work a new spectroscopic method is described to measure the ratio of free p

The monomeric octaethylhexyl- and tetra-tert-butyl-substituted phthalocyanines 3 and 12 with axial acetylacetonate as ligands were synthesized and characterized, in order to compare their optical limiting properties with the state-of-the-art molecule
