Combination of perylene derivatives and MoS2 exhibit contrasting photoluminescence (PL) behavior. The intense PL emission exhibits in PTCDA/MoS2 while quenching in PTCDI‐Ph/MoS2. The observed giant PL enhancement of PTCDA/MoS2 is due to the reduced bandgap, large exciton/trion ratio, and ordered morphology of PTCDA. The results can stimulate optoel...
