We report a computational study on enhancing the rectification ratio (RR) of the pyrene-benzene junction by modifying the structure of its acyclic aliphatic hydrocarbon bridge. The RR values for a series of pyrene-benzene systems with different types of bridges are determined. Notably. the maximum RR of the pyrene-(CH)3-(CH2)3-(CH)3-benzene system is 93. https://www.nacrack.com/flash-deal-Diamond-Painting-Zee-en-strand-special-find/
