Description
Tricyanoborate alkyl ethers
The invention relates to tricyanoborate alkyl ethers, a method for their preparation and their use as ionic liquids.
BACKGROUND OF THE INVENTION
The term "ionic liquid" (IL) is usually used to refer to a salt which is liquid at temperatures below 100°C, in particular at room temperature. Such liquid salts typically comprise organic cations and organic or inorganic anions, and are described inter alia in P. Wasserscheid et al., Angew. Chem., 2000, 1 12, 3926-3945.
Ionic liquids have a series of interesting properties: Usually, they are thermally stable, relatively non-flammable and have a low vapour pressure. They show good solvability for numerous organic and inorganic substances. In addition, ionic liquids have interesting electrochemical properties, for example electrical conductivity which is often accompanied by a high electrochemical stability.
These attributes give rise to many applications of ionic liquids: They can be used foremost as solvent in synthesis, as electrolyte, as lubricant and as hydraulic fluid. Moreover they serve as phase-transfer catalyst, as extraction medium, as heat-transfer medium, as surface-active substance, as plasticizer, as conductive salt, organic salt or additive in electrochemical cells, as electrolyte, as component in electrolyte formulations, wherein such electrolyte formulation comprising an ionic liquid is preferably used in electrochemical and/or optoelectronic device such as a photovoltaic cell, a light emitting device, an electrochromic or photo-electrochromic device, an electrochemical sensor and/or biosensor, particularly preferred in a dye sensitized solar cell.
Therefore, there is a fundamental need for ionic liquids having a variety of properties which open up additional opportunities for their use.
WO2012/041434 discloses the use of specific ionic liquids as component in electrolyte formulations, in particular in electrolyte formulations for electrochemical or optoelectronic devices such as dye sensitized solar cells.
WO 2010/086131 A discloses tricyanoborates of the general formula Catn+[B(CN)3(XRl)]n", wherein Rl is inter alia Ci_6 alkyl; X is inter alia oxygen; and Catn is a cation, which is
selected from the group consisting of an inorganic cation and an organic cation; with n being 1 or 2.
There was a need for stable compounds which can be used as ionic liquids or as precursors of ionic liquids. These compounds should be able to be disposed of in an environmentally friendly manner after use. They should show good performance in applications for ionic liquids, e.g. such as dye sensitized solar cells.
This task object is achieved by tricyanoborates with a fourth substituent, the fourth substituent being an alkyloxy-alkoxy residue.
Unexpectedly, the compounds of instant invention show good efficiency in dye sensitized solar cells. In this text, the following meanings are used, if not otherwise stated:
alkyl linear or branched alkyl;
Ci_q alkyl refers to any alkyl residue which contains from 1 to q carbon atoms; for example Ci_6 alkyl encompasses inter alia methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, isopentyl (3-methylbutyl), neopentyl (2,2-dimethylpropyl), n-hexyl and isohexyl (4-methylpentyl);
C2-q alkenyl refers to an alkenyl residue which contains from 2 to q carbon atoms and
contains at least one double bond, the carbon chain can be linear or branched; for example C2_4 alkenyl encompasses inter alia ethenyl, 1-methylethenyl, prop-l-enyl, prop-2-enyl, 2-methylprop-2-enyl and buta-l ,3-dienyl;
C2_q alkynyl refers to an alkynyl residue which contains from 2 to q carbon atoms and
contains at least one triple bond, the carbon chain can be linear or branched; for example C2_4 alkynyl encompasses inter alia ethynyl, prop-l-ynyl and prop-2-ynyl;
C6-io aryl refers to an aryl residue which has from 6 to 10 carbon atoms and is
unsubstituted or substituted by 1 , 2, 3 or 4 identical or different substituents
independently from each other selected from the group consisting of Ci_4 alkyl and
Ci_4 alkoxy; for example C6-io aryl encompasses inter alia phenyl, methylphenyl, methoxyphenyl, dimethylphenyl, ethylmethylphenyl, diethylphenyl and naphthyl;
cyclic alkyl or cycloalkyl include cyclo and polycyclo, such as bicyclo or tricyclo,
aliphatic residues;

Device fabrication: Photoanodes used to make the devices consisted of a screen-printed nanoparticulate mesoporous Ti02 layers. A 8 μιη thick transparent layer of 20 nm sized Ti02 particles was first printed on the fluorine doped Sn02 (FTO) conducting glass (purchased from NSG with ΙΟΩ/cm2, 4 mm thick) and subsequently coated with a 5 μιη thick second layer of 400 nm light-scattering anatase particles (CCIC, Japan). Detailed procedures for the preparation of Ti02 nanoparticles and pastes are reported in Ito, S. et al, Prog. Photovolt. Res. AppL, 2007, 15, 603. A standard C106 dye with CAS 1165943-93-0 was used as the sensitizer with the addition of dineohexyl bis-(3,3-dimethyl-butyl)-phosphinic acid
(DINHOP) as a co-adsorbent (4: 1 ratio) in a solvent mixture of 10% DMSO and tert-butanol and acetonitrile (1 :1) v/v ratio. The above-described double-layered Ti02 films were sintererd for 30 min at 500° C and immersed in the dye solution for 16 h. After sensitization they were rinsed in pure MeCN and assembled with platinized counter electrodes. The counter electrodes were prepared using conducting glass TEC 15 (purchased from NSG, resistance 15Ω/αη2, 2 mm thick) on which the drop of a solution of hexachloroplatinate acid in n- propanol was cast. Thermal platinization occured during heating the electrodes twice for 15 min at 425 °C in air. Electrodes were then sealed with a 25 micrometer thick hot-melt film (Surlyn®, Dupont) by heating the system at 100°C.
The composition of the electrolyte B which was used:
electrolyte A = DMII/EMII/compound(TEST) /I2/NBB/GNCS (12/12/16/1.67/3.33/0.67) electrolyte B = electrolyte A + sulfolane (50:50 v/v).
Devices were completed by filling the space between the electrodes with electrolyte through pre-drilled holes in the counter electrodes and the holes were sealed with a Surlyn sheet and a thin glass cover by heating. Finally, metal contacts were placed on both electrodes. Photovoltaic measurements: Photovoltaic measurements were performed under simulated sun irradiance (100 mW cm"1, equivalent of 1 sun at air mass global, AM 1.5G, at the surface of the device) provided by a 450 W Xenon light source (Oriel, USA). A Schott Kl 13 Tempax sunlight filter (Prazisions Glas & Optik GmbH, Germany) was used to correct the spectral output of the lamp in the region 350 to 750 nm. Current to voltage characteristics (in the dark
and under illumination) were obtained by applying a forward potential bias and measuring resulting current with a Keithley 2400 digital sourcemeter (Keithley, USA). A metal mask was used to precisely define the irradiated surface area (0.159 cm2). Quantum efficiencies of the cells were measured by using a SR830 lockin amplifier, however the incident light (300 W xenon lamp, ILC Technology) was focused through a Gemini- 180 double monochromator (Jobin-Yvon Ltd.). The cells were measured with an external light bias (10% Sun) provided by LED array. A black metal mask defined the cell active area to be 0.159 cm2.
