Eight red perylene dyes were synthesized to improve the optical performance of LCD color filters. Among them, dyes with bulky functional substituents at the bay and terminal positions were highly soluble in cyclohexanone, the industrial solvent currently used in the pigment dispersion method. The spectral properties and . We present a new perylene sensitizer, ID17 for dye -sensitized solar cells ( DSCs).

The dye has the capability for very high photocurrents due to strong absorption from 4to over 7nm. They have good to excellent lightfastness in watercolor paints. In recent years, several perylene derivatives . Molecular engineering of a photosensitizing dye plays a vital role in the control of excited states and charge carriers in dye -sensitized solar cells (DSCs) for performance improvement. Herein we report three metal-free donor–acceptor organic dyes by conjugating electron donors triphenylamine–cyclopentadithi.

On the basis of the N-annulated perylene electron donor and the ethynylbenzothiadiazole-benzoic acid electron acceptor, we herein report on synthesizing a structurally simple donor–acceptor (D–A) perylene dye C272. Perylene colors have also been used in automobile paints. Without the use of any coadsorbate, we have achieved an impressive power conversion efficiency. The binding affinity of the complexes increased about orders of magnitude compared to the dye without a secondary aromatic unit. The high affinity allows the complexes to act as fluorescent probes for detection.

Two perylene dyes characteristic of electron-donors phenanthrocarbazole (PC) and carbazyl functionalized PC are selected to study the complicated dynamics of excited states and charge carriers, which underlie the photovoltaic parameters of dye-sensitized solar cells (DSCs). We have combined femtosecond fluor. A structurally simple perylene dye with ethynylbenzothiadiazole-benzoic acid as the electron acceptor achieves an over power conversion efficiency†.

Six novel red perylene dyes were synthesized by modifying the bay- and terminal -positions of perylene main body to improve the optical performances of liquid crystal display (LCD) color filters. The absorption properties, solubility in industrial solvents and thermal stabilities of the dyes were examined to evaluate the dyes . Such supramolecular structures exhibit the characteristics of artificial photosynthetic systems and can potentially lead to efficient light-harvesting materials. OVERVIEW OF LIQUID-CRYSTAL-BASED PHOTOVOLTAIC CELLS Large-core HBC molecules that form DLC phases were combined with perylene dyes to form . UV-vis studies revealed the formation of J-type aggregates where the perylene bisimide units of the hydrogen-bonded triad pack tightly within the aggregates.

Significant quenching of the perylene bisimide fluorescence is notice suggesting electron transfer from OPV to perylene bisimide. In addition, a strong negative .
