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

Abstract

AbstractOrganic 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.
