Bromine-Enhanced Organic Materials for X-ray Sensors: Unveiling the Potential of Small Molecules and Polymers through Material Design and Film Fabrication

Organic X-ray sensors are a promising new class of detectors with the potential to revolutionize medical imaging, security screening, and other applications. However, the development of high-performance organic X-ray sensors is challenged by low sensitivity. This paper reports on the development of nine X-ray sensors based on new organic materials. It is demonstrated that the incorporation of bromine atoms into the sidechains of carbazolyl-containing organic molecules significantly enhances their X-ray sensitivity. This research suggests that incorporating a variety of high-atomic-number chemical elements into well-established organic semiconductors is a promising strategy for designing efficient X-ray sensor materials.
