Abstract:In this study we develop a strategy to insulate 6,6 ‐Phenyl C61 butyric acid methyl ester (PCBM) on the basal plane of transition metal dichalcogenides (TMDs). Concretely single layers of MoS2, MoSe2, MoTe2, WS2, WSe2 and WTe2 and ultrathin MoO2 and WO2 were grown via chemical vapor deposition (CVD). Then, the thiol group of a PCBM modified with cysteine reacts with the chalcogen vacancies on the basal plane of TMDs, yielding PCBM‐MoS2, PCBM‐MoSe2, PCBM‐WS2, PCBM‐WSe2, PCBM‐WTe2, PCBM‐MoO2 and PCBM‐WO2.
