Lead Performer: Kebotix – Cambridge, MA

DOE Total Funding: $198,094
Project Term: June 29, 2020 – March 28, 2021
Funding Type: Small Business Innovation Research (SBIR) Project

PROJECT OBJECTIVE

Solution-processed organic light-emitting materials suffer from uncontrollable aggregation of pigments, which leads to quenching of the emission. This project aims to develop organic molecules that exploit the aggregation in an aggregation-induced emission phenomenon. While others are investigating host-free thermally activated delayed fluorescence (TADF) materials using vapor deposition, this project will focus on solution-processable materials for low cost and high throughput, applying Kebotix’s proprietary pipeline for a multilevel smart-throughput screening of organic molecules and aggregates, to identify blue emitters with reduced quenching and high efficiency. The project will focus on small organic molecules that are compatible with solution-processing methods of film deposition. Top candidates will be synthesized and characterized and assembled into devices. The developed technology is targeted to the design of largescale manufacturing of organic lighting devices that are price-competitive with their inorganic counterparts.

PROJECT IMPACT

Blue emitter materials that are sufficiently stable and efficient have not yet been identified. This project proposes employing data mining and machine learning to quickly and cost-effectively identify potential candidates for blue TADF materials, which could lead to high-efficiency devices.
