We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm-2): short-circuit current density (J sc) = 18.1 mA cm-2, open circuit photovoltage (V oc) = 743 mV and fill factor (ff) = 0.675.

A new visible-light-excitable fluorescence ratio-metric probe for OCl- has been developed based on a triphe-nylamine-diamiomaleonitrile (TAM) moiety. The structure of the dye was confirmed by single-crystal X-ray analysis. It behaves as a highly selective and sensitive probe for OCl- over other analytes with a fast response time (~100s). OCl- reacts with the probe leading to the formation of the corresponding aldehyde in a mixed-aqueous system. The detection limit of the probe is in the 10-8m range. The probe (TAM) also exhibits solvatofluorochromism. Changing the solvent from non-polar to polar, the emission band of TAM largely red-shifted. Moreover, the probe shows an excellent performance in real-life application in detecting OCl- in human blood cells. The experimentally observed changes in the structure and electronic properties of the probe after reaction with OCl- were studied by DFTand TDDFT computational calculations.

The invention relates to a phenanthrene-containing phenanthroimidazole luminescent material as well as a preparation method and application thereof. With the carbonyl compound and diethyl (4 -cyanobenzyl) phosphonate as raw materials, the Wittig-Honor reaction is carried out. Redox reaction, debus-radziszewski ' one-pot process' produces phenanthrene-containing phenanthrene compounds. The method can utilize the characteristic infrared absorption of formyl and cyano in the infrared spectrum to monitor the reaction process. A precious metal catalysis carbon-carbon coupling reaction is avoided in the reaction process. And yield is high. The invention provides a new method for synthesizing phenanthrene-containing phenanthrene compounds. In addition, the phenanthrene-containing phenanthroimidazole compound provided by the invention can be directly applied to ultraviolet excited organic/inorganic hybrid white LED devices as an organic luminescent material, and a technical reference is provided for application thereof.

A series of donor–π–acceptor-type sulfonium salt photoacid generators (PAGs) were designed and synthesized by systematically changing electron-donating groups, π-conjugated systems, electron-withdrawing groups, and the number of branches through molecular engineering. These PAGs can effectively decompose under UV/Vis irradiation from a light-emitting diode (LED) light source because of the matching absorption and emitting spectra of the LEDs. The absorption and acid-generation properties of these sulfonium salts were elucidated by UV/Vis spectroscopy and so forth. Results indicated that the PAG performance benefited from the introduction of strong electron-donating groups, specific π-conjugated structures, certain electron-withdrawing groups, or two-branched structures. Most sulfonium salts showed potential as photoinitiators under irradiation by a wide variety of UV and visible LEDs.
