{Achieving|Reaching|Attaining} {high|higher} rectifying {performance|overall performance|efficiency|functionality} of molecular scale diode devices {through|via|by means of|by way of} synthetic chemistry and device {construction|building} {remain|stay} a formidable challenge {due to|because of|as a result of|on account of|resulting from|as a consequence of} the complexity {of the|from the|in the|on the|with the|of your} charge transport {process|procedure|method|approach|course of action} {and the|and also the|as well as the|along with the|plus the} device structure.
