Efficient　charge　carrier　transport　in　organic　thin　film　transistors　(OTFTs)　often　requires　thin　films　with　highly　oriented　feature.　Although　there　are　a　number　of　methods　to　effectively　form　high-degree　and　large-scale　alignment　during　the　process　of　film　formation,　these　methods　usually　resulted　in　nonuniform　films.　In　order　to　obtain　highly　aligned　uniform　films,　this　paper　provides　a　postalignment　method　after　film　formation.　By　applying　electric　field　during　solvent　annealing,　the　polymer　backbone　can　be　reorganized　along　the　direction　of　the　electric　field,　leading　to　highly　aligned　polymer　chains　and　significant　improvement　in　charge　mobility.　In　addition,　after　doping　the　polymer　films　with　liquid　crystal　(LC),　with　the　benefit　of　LC　molecules＇　template,　the　degree　of　orientation　of　polymer　molecular　chains　was　further　enhanced,　resulting　in　further　improvement　of　the　charge　mobility　up　to　9.42　cm2V-1　s-1.　This　paper　exhibits　the　possibility　of　improving　charge　transport　after　film　formation　to　obtain　high-performance　solution-processable　OTFT　for　low-cost　and　large-scale　organic　electronics.　©　1963-2012　IEEE.
