According to a screening method that was recently developed by a team of chemists working at the Goethe University in Frankfurt, we can now easily identify structure meant for Organic Light Emitting Diodes (OLEDs) with much better luminescence along with many other charge-transport properties. According to the research team that was working on this project, organic materials are counted among some of the most effective sources for meeting the increasing demand for display technologies. In a specific manner, molecules from this class of materials are called as polycyclic aromatic hydrocarbons (PAHs) can always be used in the production of flexible large sized flat screens that have higher resolution and lower energy consumption.
The research team has been working on finding new kinds of organic luminescent materials that give away their promising properties to atoms of borons into PAH scaffold, however, their synthesis prerequisites are pretty complicated and take a lot of time. A screening process that was developed recently, this new process makes the availability of PAHs quick and simpler, it means the future situation will also be secured by it. This technique allows users to evaluate their potential in form of OLED materials. Alexandra John, a doctoral researcher adds, “For a long time, it has been pharmaceutical research which has profited from screening processes. Yet it makes sense in the dynamic and growing field of organic materials to use similar strategies to achieve results in a cost-efficient and resource-friendly way.”
This procedure is primarily dependent on a three-component reaction. Under this reaction, two components stay constant under all reactions while the third one is selected from a wide range of low-cost PAHs. The material with boron plays a very significant role in assembling of the molecular scaffold. Apart from this, it has been said that the compounds acquired from desired optoelectronic properties by enhancing luminescence and bringing required modifications in electrical conductivity.
