Manufacturing Organic-Inorganic Nanoparticle Composites with Nanoscale Precision via Directed Self-Assembly

New materials that interact with light and electricity, like organic semiconductors and nanoparticles, are behind exciting technologies such as organic light-emitting diodes (OLEDs) and the bright displays found in QD TVs and LED lights. A particularly exciting development is blending organic semiconductors with inorganic nanoparticles. These hybrid materials could lead to highly efficient, affordable solar panels, light sensors, and next-generation LEDs for screens, communication tools, and chemical testing.

To produce these materials on a large scale, scientists use a process called solution processing. This involves creating an “ink” made of organic semiconductors, nanoparticles, and a suitable solvent, which is then used to create thin films or coatings. However, one major challenge is that the different components often separate or clump together due to their different sizes and surface properties. This separation can reduce the performance of the final product.

This project aims to solve that problem by finding ways for these components to naturally arrange themselves in the right structure as the solvent dries. This self-assembly process would result in a well-organized blend of materials that maintains its structure across different scales. Additionally, the project seeks to develop manufacturing methods for these new optoelectronic and photonic films and coatings. The goal is to turn these advanced materials into real-world products that can benefit both the UK’s economy and people around the world.
