Coumarins have been studied extensively for their applications in electronic and photonic devices. They possess high emission yield, excellent photo-stability, variable absorption range, and good solubility. As such, coumarins are widely used as fluorescence probes, charge-transfer materials, and dyes for OLEDs, OPV and laser dye applications. C545T is commonly used for highly-efficient OLED devices as a green-emitting dopant and electron transport host material. With four methyl groups and enhanced solubility, Coumarin 545T is also used in laser dyes with increased laser conversion efficiencies at higher concentrations.

They possess high emission yield, excellent photo-stability, variable absorption range, and good solubility. As such, coumarins are widely used as fluorescence probes, charge-transfer materials, and dyes for OLEDs, OPV and laser dye applications.</p> <p>C545T is commonly used for highly-efficient OLED devices as a green-emitting dopant and electron transport host material. With four methyl groups and enhanced solubility, Coumarin 545T is also used in laser dyes with increased laser conversion efficiencies at higher concentrations.</p> <h2>General Information</h2> <hr> <table> <tbody> <tr> <th width="25%">CAS number</th> <td width="75%">155306-71-1</td> </tr> <tr> <th>Chemical formula</th> <td>C<sub>26</sub>H<sub>26</sub>N<sub>2</sub>O<sub>2</sub>S</td> </tr> <tr> <th>Molecular weight</th> <td>430.56 g/mol</td> </tr> <tr> <th>Absorption*</th> <td>λ<sub>max</sub> 473 nm (in THF)</td> </tr> <tr> <th>Fluorescence</th> <td>λ<sub>em</sub> 506 nm (in THF)</td> </tr> <tr> <th>HOMO/LUMO</th> <td>HOMO = 5.6 eV, LUMO = 3.0 eV [2]</td> </tr> <tr> <th>Synonyms</th> <td>10-(2-Benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H,11H-(1)benzopyropyrano(6,7-8-I,j)quinolizin-11-one, Coumarin 545T</td> </tr> <tr> <th>Classification / Family</th> <td>Coumarins, Electron transport-layer (ETL) materials, Green dopant materials, Organic Light-Emitting Diodes (OLEDs), Organic photovoltaics (OPV), Organic electronics, Laser dyes, Sublimed materials</td> </tr> </tbody> </table> <p>* Measurable with an optical spectrometer</p> <h2>Product Details</h2> <hr> <table> <tbody> <tr> <th width="25%">Purity</th> <td width="75%">>99% (sublimed*)</td> </tr> <tr> <th>TGA</th> <td>228°C, T<sub>d </sub>≥ 250 <sup>o</sup>C (5% weight loss)</td> </tr> <tr> <th>Colour</th> <td>Pale yellow - Yellow powder/crystals</td> </tr> </tbody> </table> <p>* Sublimation is a technique used to obtain ultra pure-grade chemicals, see <a href="https://www.ossila.com/collections/sublimed-materials" title="sublimed materials" target="_blank">sublimed materials</a>.</p> <h2>Chemical Structure</h2> <hr> <figure><a href="https://www.ossila.com/cdn/shop/files/C545T.png?v=1718724890"> <img alt="C545T chemical structure" height="160" loading="lazy" src="https://www.ossila.com/cdn/shop/files/C545T.png?v=1718724890&width=240" width="240"></a> <figcaption>Chemical Structure of C545T</figcaption> </figure> <h2>Device Structure(s)</h2> <hr> <table> <tbody> <tr> <th width="25%">Device structure</th> <td width="75%">ITO/Mg (1 nm)/Cs<sub>2</sub>O:Bphen (11 nm)/Alq<sub>3</sub> (30 nm)/<strong>C545T</strong>:Alq<sub>3</sub> (30 nm)/NPB (60 nm)/WO<sub>3</sub> (5 nm)/Al [1]</td> </tr> <tr> <th>Colour</th> <td>Green <img alt="green light emitting device" height="44" loading="lazy" src="https://www.ossila.com/cdn/shop/files/green.png?width=50&height=44" width="50"> </td> </tr> <tr> <th>Max.
