We have recorded the electronic spectra of benzo[g,h,i]perylene and coronene and their van der Waals complexes with argon and oxygen with a helium-nanodroplet depletion spectrometer. These molecules differ by the addition of one and two fused benzene rings to perylene, which was previously studied in helium. The coronene spectrum is similar to a previously reported jet-cooled laser-induced fluo...

A dendritic oligothiophene containing perylene bis(dicarboximide) units was synthesized and its electronic properties and photovoltaic performance were investigated.

The temperature-dependent fluorescence anisotropy decay (orientational relaxation) of perylene and sodium 8-methoxypyrene-1,3,6-sulfonate (MPTS) were measured in a series of 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (alkyl = ethyl, butyl, hexyl, octyl) organic room temperature ionic liquids (RTIL). The two fluorescent probe molecules display markedly different rotational dy...

The orientational relaxation dynamics of perylene in the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium bis(trifluoromethyl)sulfonyl imide were studied as a function of lithium ion concentration. Perylene is nonpolar and locates in the alkyl regions of the RTIL. The lithium cation was added as lithium bis(trifluoromethyl)sulfonyl imide, so the addition of Li(+) did not change ...

Novel double-stranded polyacetylene with a perylene bisimide bridge has been efficiently synthesized by metathesis cyclopolymerization of bis(1,6-heptadiyne) derivatives, and exhibited good solubility, highly thermal and oxidative stability, low LUMO energy levels, narrow bandgaps, and regular ladder-like architecture.

The high fluorescent potential and the exceptional photostability of lipophilic derivatives of perylene-3,4:9,10-bis(dicarboximides) are utilized for the fluorescence-labelling of liposomes. The preparation of the liposomes is effected by supersonic starting from a lipid mixture consisting of the matrix lipids soy lecithin, cholesterol, alpha-tocopherol and the perylene dyes. From a multitude o...

Kamal Sbargoud, Masashi Mamada,* Jérôme Marrot, Shizuo Tokito, Abderrahim Yassar* and Michel Frigoli* Diindeno[1,2-b:20,10-n]perylene, a new derivative of the indenoacene family was synthesized, and its electronic, electrochemical, and electrical properties were investigated. This material has a closed shell electronic configuration which corresponds to a quinoidal structure with a low band gap...

A red-fluorescent perylene diimide probe allows sensitive quantification of heparin, a widely used antithrombotic drug, in plasma and serum samples with minimal interference from matrix components.
