商品介绍

4,4′-Bis(N-carbazolyl)-1,1′-biphenyl (CBP), is one of the most widely-used host materials for efficient fluorescent and phosphorescent organic light-emitting diodes with high hole mobility. This is due to its electron-rich property from two carbazolyl units.

It has been demonstrated that CBP can efficiently host green, yellow and red phosphorescent emitters with triplet energies smaller than that of CBP (ET = 2.6 eV) [1].

品牌介绍

Ossila was founded in 2009 by organic electronics research scientists with the aim of providing the components, equipment and materials to enable faster and smarter research and discovery. We have grown a lot since then and are proud to now supply our products to over 1000 different institutions in over 67 countries across the world.

Having spent many years both in industry and academia developing organic and thin film LEDs, photovoltaics and FETs, we know how long it takes to develop a reliable and efficient device fabrication and testing process. As such, we have developed packages of products and services to enable researchers to jump-start their organic electronics or materials research development program.

Our research scientists have significant experience in the processing of materials into LEDs, PVs and FETs, and amongst our team of physicists, chemists and engineers we have a huge collection of knowledge on thin film processing, electronics and characterisation. 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.
