atomically thin h-BN interlayer to investigate its possible decoupling effect. To this end, we use in situ differential reflectance spectroscopy as an established method to distinguish between hybridized and decoupled molecules. By inserting an h-BN interlayer we fabricate a buriedinterface and show that
n-type contact for future molecular electronic devices.

The interfaces between organic molecules and metal contacts play a crucial role in
, structural and electronic properties of DBP on Ni(111). By inserting the h-BN layer, we fabricated a buriedinterface, and a monomer-like behavior was observed by means of DRS instead of a strong hybridization, which occurs on the bare metal substrate. Therefore, we conclude that one h-BN layer is sufficient
