For studies of organic and molecular electronics, eliminating structural defects in molecular components inside devices is usually needed for improving their performance. This presentation shows that this bother can be turned into a strength for modulating the performance of devices. A monolayer of an organic rectifier, 2,2′-bipyridine-terminated n-undecanethiolate, is systematically diluted with electronically inactive diluents, n-alkanethiolates of different lengths. Such a dilution leads to remarkable gradients of rectification in a range of approximately two orders of magnitude, retaining its polarity. Trends of rectification against the length of the diluent indicate the gradient of rectification is extremely sensitive to the molecular structure of the diluent. Further studies reveal that noncovalent intermolecular interactions within monolayers result in finely tunable gradients of structural defect and rectification.
