Over the past two decades, the performance of organicbased
eld effect transistors (FETs) has achieved signi cant advance
ment on account of chemical modi cation of existing frameworks,
synthesis of novel organic materials and optimization of different
device fabrication techniques. Employing polymers or small mol
ecules that have semiconductor property to control electric current
are particularly attractive as the production processes are much less
complex and naturally compatible with plastic substrates. Yet,
limited transistor mobility and short lifetime hinder the range of
potential applications. Challenges still remain on the development
of augmentative materials and feasible fabrication systems for high
performance transistors and exible electronics.
An appropriate way to generate high performance solution
processed transistors is to tailor two or more components by
merging their functionality. For instances, acquiring an ambipolar
transistor having both nchannel and pchannel organic materials
provides the possibility to fabricate complementary logic devices
