An efficient approach for preparing functional organic field‐effect transistors (OFETs) by using spiropyran (SP)‐ co ‐methyl metharylate (MMA) as the photoactive gate dielectrics is developed by Xuefeng Guo and co‐workers and reported in article number 1500159. SP photoisomerization initiates reversible changes in the dipole moment of the SPs, leading to fine tuning of the carrier density in the conductive channel of the OFETs through interface engineering.
