Chirality dependence of the absorption cross-section of carbon nanotubes.

The variation of the optical absorption of carbon nanotubes with their geometry has been a long standing question at the heart of both metrological and applicative issues, in particular because optical spectroscopy is one of the primary tools for…

Light harvesting with non covalent carbon nanotube / porphyrin compounds.

We present recent developments in the synthesis and in the functional study of non covalently bound porphyrin/carbon nanotube compounds. The issue of the chemical stability of non covalent compounds is tackled by means of micelle assisted chemistry…

The first hexadithienylethene-substituted tris(bipyridine)metal complexes as quadratic NLO photoswitches: combined experimental and DFT studies.

Flip the NLO switch! A straightforward access to hexadithienylethene-based photochromes by using a coordination-chemistry approach through the combination of bis(dithienylethene)bipyridyl ligands and metal ions (M = Zn, Fe) is reported. The…

Monolithic microcavity with carbon nanotubes as active material

We report on the realization of monolithic optical microcavities using a single wall carbon nanotubes doped polymer as active material. Thanks to the control of the polymer thickness, a ne control of the cavity mode energy is achieved, which allows…

Selective Cold Welding of Colloidal Gold Nanorods

A new cold nanowelding technique for cetyltrimethylammonium bromide (CTAB)-stabilized colloidal nanorods in water is reported. This technique leads to the formation of micrometric nanowires by end-to-end self-organization and welding of nanorods…
