This talk will describe interfacial photophysical processes in heterojunctions comprising 0D materials (molecules, quantum dots) with 2D or layered materials, such as atomically thin metal dichalogenides. Particular focus will be on charge and energy transfer processes between metal phthalocyanines and monolayer MoS<sub>2</sub>, which display interfacial coupling and molecular organization that depends on the metal center of the phthalocyanine. This organization, in the case of Cu phthalocyanine, leads to exceptionally long-lived charge-separated states (70 ns) that are promising for applications in solar energy conversion.
