Photoemission spectroscopy of the perylene layers on Au(110) surface was performed using a momentum microscope. The two-dimensional maps monolayer exhibit “binary star” pattern with two asymmetric bright spots for electrons from highest occupied molecular orbital perylene, reflecting tilted orientation. This absent multilayer and Br-doped because random orientation molecules in these layers. Br...

A new experimental high-pressure setup for measuring diffusion coefficients in supercritical fluids, based on Taylor dispersion method, and using an FTIR detector to operate up 25.0 MPa was designed optimized. Tracer diffusivities, D12, of toluene benzene carbon dioxide were measured the temperature range 306.15–320.15 K, pressure 7.5–17 evaluate protocol. The effects flow velocity, volume cell...

Ultrafast recombination observed from several perylene imide sensitizers bound to NiO appears to align with Marcus normal region behaviour; this indicates recombination to intra-bandgap states.

New perylene monoimides, diimides and bis-diimides have been designed and synthetized. A detailed investigation of the synthesis of these compounds has also been performed in order to highlight the crucial factors for obtaining a specific class of molecules. Specifically, the attention has been focused on the synthesis of the intermediate perylene monoimides which are very useful precursors for...

High-performance solution-processed organic semiconductors maintain macroscopic functionality even in the presence of microscopic disorder. Here we show that the functional robustness of certain organic materials arises from the ability of molecules to create connected mesoscopic electrical networks, even in the absence of periodic order. The hierarchical network structures of two families of i...

Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesized novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H2 gas sensors based upon proton acceptors. The two N atoms of the pyridyl rings which work as proton acceptors are found to remain unbon...

We investigate how apparent slight changes to the chemical structure of amino acid-functionalised perylene bisimides (PBIs) affect self-assembled aggregates formed and their resulting physical optical properties.

NIR absorbing J-aggregates with biomimetic features of chlorophyll dye assemblies are obtained upon hydrogen-bond directed self-assembly of a green 1,7-diamino-substituted perylene bisimide dye.

A high performance three-dimensional (3D) thiophene-annulated perylene dye, namely tetra-PBI-S, was designed and synthesized. The appropriate LUMO level, balanced carrier mobilities and favourable phase separation make tetra-PBI-S based solar cells show a much higher power conversion efficiency (PCE) of 6.2% than tetra-PBI based solar cells with a PCE of 3.6%.
