a) Chemical structure of the anthracene‐functionalized curcuminoid molecules (1,7‐(di‐9‐anthracene)‐1,6‐heptadiene‐3,5‐dione). b) Schematics of a single molecule bridging a graphene nanogap. c) I–V characteristics of the nanogapped electrodes before and after being bridged by molecules at 300 K. d) Dependence of the I–V characteristics of the nanogapped electrodes bridged by molecules on the applied back‐gate voltage measured at 300 K.
