Detection of explosives with a fluorescent nanofibril film.
A new type of fluorescence sensory material has been developed from an alkoxycarbonyl-substituted carbazole-cornered tetracycle, which facilitates long-range exciton migration and favors adsorption and diffusion of gaseous adsorbates within the film. Expand
Fenton degradation of organic pollutants in the presence of low-molecular-weight organic acids: cooperative effect of quinone and visible light.
It is concluded that coupling visible irradiation and hydroquinone could be a strong and universal driving force in the Fenton reaction for the complete degradation and mineralization of organic pollutants, even in the presence of LMWOAs. Expand

Effect of side-chain substituents on self-assembly of perylene diimide molecules: morphology control.
The aggregate of DD-PTCDI shows a pronounced absorption band at the longer wavelength, whereas the absorption of ND-P TCDI aggregate is not significant in the same wavelength region, and optical spectral observations are reminiscent of the previous theoretical investigation on the side-chain-modulated electronic properties of PTCDI assembly.

Surface-assisted one-dimensional self-assembly of a perylene based semiconductor molecule.
Chloroform-vapor annealing of thin films of propoxyethyl perylene tetracarboxylic diimide leads to formation of well-defined one-dimensional self-assemblies, which show optically uniaxial properties as demonstrated by the linearly polarized emission. Expand
Photocatalytic bleaching of p-nitrosodimethylaniline in TiO2 aqueous suspensions: A kinetic treatment involving some primary events photoinduced on the particle surface
Abstract The photocatalytic bleaching of p -nitrosodimethylaniline (P) has been investigated in aqueous suspensions of TiO 2 . It was found that both charge carriers (hole and electron) were reactiveExpand
Ultralong nanobelts self-assembled from an asymmetric perylene tetracarboxylic diimide.
Ultralong nanobelts have been fabricated from an asymmetric perylene tetracarboxylic diimide molecule via a seeded self-assembly processing and more than 3 orders of magnitude increase in current was observed for a single nanobelt when exposed to the saturated vapor of hydrazine. Expand
Large gate modulation in the current of a room temperature single molecule transistor.
A single molecule field effect transistor (FET) which consists of a redox molecule covalently bonded to a source and drain electrode and an electrochemical gate is demonstrated, in the fashion of an n-type FET. Expand
Ultraselective fluorescent sensing of Hg2+ through metal coordination-induced molecular aggregation.
A new type of fluorescent sensor has been developed from a perylene based molecule, N,N'-dideoxythymidine-3,4,9,10-perylene-tetracarboxylic diimide (TT-PTCDI), which enables efficient sensing of mercury ions based on a fluorescence quenching mechanism. Expand
