Chemical compatibility between a hole conductor and organic dye enhances the photovoltaic performance of solid-state dye-sensitized solar cells

A series of organic dyes having an unsymmetrical geometry, 3-(5′-{4-[(4-tert-butyl-phenyl)-(4-fluoro-phenyl)-amino]-phenyl}-[2, 2′]bithio-phenyl-5-yl)-2-cyano-acrylic acid (D-F), 3-(5′-{4-[(4- tert-butyl-phenyl)-p-tolyl-amino]-phenyl}-[2,2′] bithiophenyl-5-yl)-2- cyano-acrylic acid (D-CH3), and 3-(5′-{4-[(4-tert-butyl-phenyl) -(4-methoxy-phenyl)-amino]-phenyl}-[2,2′]bithiophenyl-5-yl) -2-cyano-acrylic acid (D-OCH3), were designed and synthesized for use in solid-state dye-sensitized solar cells (sDSCs). The dye regeneration energy levels and surface properties were characterized to determine the hole transfer yield from the oxidized dye to the hole conductor (spiro-OMeTAD) by measuring the degree of pore-filling by the spiro-OMeTAD and the transient absorption spectra (TAS). An electrode sensitized with D-OCH3 exhibited the highest spiro-OMeTAD filling fraction and hole transfer quantum yield (Φ) to spiro-OMeTAD, resulting in an enhanced photocurrent and a power conversion efficiency of 3.56% in the sDSC, despite a lower energy driving force for hole transfer compared to those of D-F, or D-CH3. This result illustrates the importance of the chemical compatibility between the hole conductor and the dye on the surface of TiO2. The Royal Society of Chemistry 2012.

The structure-activity relationships of L3MBTL3 inhibitors: Flexibility of the dimer interface

We recently reported the discovery of UNC1215, a potent and selective chemical probe for the L3MBTL3 methyllysine reader domain. In this article, we describe the development of structure-activity relationships (SAR) of a second series of potent L3MBTL3 antagonists which evolved from the structure of the chemical probe UNC1215. These compounds are selective for L3MBTL3 against a panel of methyllysine reader proteins, particularly the related MBT family proteins, L3MBTL1 and MBTD1. A co-crystal structure of L3MBTL3 and one of the most potent compounds suggests that the L3MBTL3 dimer rotates about the dimer interface to accommodate ligand binding.

One-point binding ligands for asymmetric gold catalysis: Phosphoramidites with a TADDOL-related but acyclic backbone

Readily available phosphoramidites incorporating TADDOL-related diols with an acyclic backbone turned out to be excellent ligands for asymmetric gold catalysis, allowing a number of mechanistically different transformations to be performed with good to outstanding enantioselectivities. This includes [2 + 2] and [4 + 2] cycloadditions of ene-allenes, cycloisomerizations of enynes, hydroarylation reactions with formation of indolines, as well as intramolecular hydroaminations and hydroalkoxylations of allenes. Their preparative relevance is underscored by an application to an efficient synthesis of the antidepressive drug candidate (-)-GSK 1360707. The distinctive design element of the new ligands is their acyclic dimethyl ether backbone in lieu of the (isopropylidene) acetal moiety characteristic for traditional TADDOLs. Crystallographic data in combination with computational studies allow the efficiency of the gold complexes endowed with such one-point binding ligands to be rationalized.

New organic dye based on a 3,6-disubstituted carbazole donor for efficient dye-sensitized solar cells

We have synthesized and characterized four organic dyes (H1-H4) based on a 3,6-disubstituted carbazole donor as sensitizers in dye-sensitized solar cells. These dyes have high molar extinction coefficients and energy levels suitable for electron transfer from an electrolyte to nanocrystalline TiO2 particles. Under standard air mass 1.5 global (AM 1.5 G) solar irradiation, a device using dye H4 exhibits a short-circuit current density (Jsc) of 13.7 mA cm-2, an open-circuit voltage (Voc) of 0.68 V, a fill factor (FF) of 0.70, and a calculated efficiency of 6.52 %. This performance is comparable to that of a reference cell based on N719 (7.30 %) under the same conditions. After 1000 hours of visible-light soaking at 60 °C, the overall efficiency remained at 95 % of the initial value. Metal-free sensitizer: Four organic dyes based on a 3,6-disubstituted carbazole donor have been synthesized for their potential use as sensitizers in dye-sensitized solar cells. These dyes have high molar extinction coefficients and energy levels suitable for electron transfer from an electrolyte to nanocrystalline TiO 2 particles. Under standard global AM 1.5 solar irradiation, a device using one of the prepared dyes (see graphic) exhibited a calculated efficiency of 6.52 %.

Conjugated polymer sensors built on ?-extended borasiloxane cages

An efficient 2 + 2 cyclocondensation with dihydroxysilane converted simple arylboronic acids to bifunctional borasiloxane cage molecules, which were subsequently electropolymerized to furnish air-stable thin films. The extended [p,?]-conjugation that defi
