The phenomenon of neutrinoless double beta decay is a rare nuclear event where two protons transform into two neutrons spontaneously. Despite being theoretically described; its experimental observation remains elusive. This event holds significant potential for unraveling insights into neutrinos and the early universe. Detecting neutrinoless double beta decay necessitates sensitive detectors capable of capturing decay products, particularly barium ions. However, current barium sensing molecules exhibit drawbacks such as limited solubility and specificity. This study endeavors to synthesize novel barium sensing molecules tailored for neutrinoless double beta decay experiments. Our approach involves designing and synthesizing calix[4]erane-based molecules optimized for this purpose. Specifically, we plan to employ a p-tert butyl calix[4]erane binding motif linked to either a napthalimide or BODIPY fluorophore for barium detection post neutrinoless double beta decay. Characterization of these molecules will be conducted using a blend of organic synthesis and spectroscopy techniques, focusing on properties like selectivity, sensitivity, and solubility. The development of efficient barium sensing molecules promises enhanced detection capabilities for neutrinoless double beta decay, contributing significantly to our comprehension of fundamental physics.
