The control of superconducting thin film properties through the adsorption of organic molecules has attracted attention as a novel method for tuning superconductivity. However, conventional superconducting thin film materials often suffer from poor air stability and limited responsiveness to external stimuli. In this study, we focused on the oxide superconductor LiTi2O4, which is both air-stable and possesses relatively low electron density. By adsorbing organic molecules onto its surface, we investigated changes in its transport properties. As a result, we observed a reversible suppression and recovery of the superconducting transition via molecular adsorption and desorption, along with significant resistance changes even above 50 K.
