2,1,3-Benzothiadiazole-4,7-bis(boronic acid pinacol ester) is an intermediate for the synthesis of small molecules, oligomers and polymers via Suzuki Coupling reactions. Those small molecules, oligmomers and polymers can be printed, spray-coated or spin-coated onto devices for Organic Light-Emitting Diodes (OLED/PLED), Organic Field-Effect Transistors and Organic Photovoltaic devices.

2,1,3-Benzothiadiazole unit is electron deficient so it is employed for the low-band gap semiconducting materials used for OLED and OPV devices, i.e. F8BT and PCPDTBT.

Have already recommended to many people. Dr. Gregory Welch, University of Calgary Wonderful company with reasonably priced products and so customer-friendly! Shahriar Anwar, Arizona State University The Ossila Team Prof. David Lidzey - Chairman As professor of physics at the University of Sheffield, Prof. David Lidzey heads the university’s Electronic and Photonic Molecular Materials research group (EPMM). During his career, David has worked in both academic and technical environments, with his main areas of research including hybrid organic-inorganic semiconductor materials and devices, organic photonic devices and structures and solution processed photovoltaic devices. Throughout his academic career, he has authored over 220 peer-reviewed papers. Dr. James Kingsley - Managing Director James is a co-founder and managing director of Ossila. With a PhD in quantum mechanics/nanotech and over 12 years’ experience in organic electronics, his work on the fabrication throughput of organic photovoltaics led to the formation of Ossila and the establishment of a strong guiding ethos: to speed up the pace of scientific discovery. James is particularly interested in developing innovative equipment and improving the accessibility of new materials for solution-processable photovoltaics and hybrid organic-inorganic devices. Dr. Alastair Buckley - Technical Director Alastair is a lecturer of Physics at the University of Sheffield, specialising in organic electronics and photonics. He is also a member of the EPMM research group with a focus on understanding and applying the intrinsic advantages of functional organic materials to a range of optoelectronic devices. Alastair’s experience has not been gained solely in academia; he previously led the R&D team at MicroEmissive Displays and therefore has extensive technical experience in OLED displays. He is also the editor and contributor of "Organic Light-Emitting Diodes" by Elsevier. Our Research Scientists Our research scientists and product developers have significant experience in the synthesis and processing of materials and the fabrication and testing of devices. The vision behind Ossila is to share this experience with academic and industrial researchers alike, and to make their research more efficient. By providing products and services that take the hard work out of the device fabrication process, and the equipment to enable accurate, rapid testing, we can free scientists to focus on what they do best - science. Customer Care Team The customer care team is responsible for the customer journey at Ossila. From creating and providing quotes, through to procurement and inventory management, the customer care team is devoted to providing first class customer service. The general day to day responsibilities of a customer care team member involves processing customers orders and price queries, answering customer enquiries, arranging the shipment of parcels and notifying customers of updates on their orders. Collaborations and Partnerships Please contact the customer care team for all enquires, including technical questions about Ossila products or for advice on fabrication and measurement processes. Location and Facilities Ossila is based at the Solpro Business Park in Attercliffe, Sheffield. We operate a purpose-built synthetic chemistry and device testing laboratory on site, where all of our high-purity, batch-specific polymers and other formulations are made. This is complemented by a dedicated suite of thin-film and organic electronics testing and analysis tools within the device fabrication cluster housed in a class 1000 cleanroom in the EPSRC National Epitaxy Facility in Sheffield. All our electronic equipment is manufactured on-site.
