摘　　要：Organic electrolyte-gated transistors(OEGTs) have the benefits of low power consumption and large current modulation.Nevertheless,the electrical performance of n-type OEGTs lags far behind that of p-type OEGTs.In this study,we design a series of polymers,P(NDITEG-T) and P(NDIMTEG-T),comprising a naphthalene diimide backbone for n-type charge transport and oligo(ethylene glycol)(OEG) side chains for high ionic conductivity and eco-friendly solution processing.The incorporation of the OEG chain facilitates the electrochemical doping of the semiconductor by ions to realize high-performance,n-type OEGTs.Notably,in OEGTs,P(NDITEG-T) achieves a high electron mobility of 1.0 × 10^(-1) cm^(2) V^(-1) s^(-1),which represents the highest value reported for solution-processed,n-type OEGTs.It is noted that the fabrication of the OEGTs is achieved by solution processing with eco-friendly ethanol/water mixtures in virtue of the hydrophilic OEG chains.This work demonstrates the molecular design of the P(NDITEG-T) polymer and its significant ability to produce aqueous-processable,high-performance,and n-type OEGTs.
