“…Noh et al reported the fabrication of P184-based OFET's, processed using a non-halogenated binary solvent system, by using the HSP analysis method. 88 The P184-based OFET exhibited a high mobility of 0.574 cm 2 V À1 s À1 , which could be attributed to the properties of the pre-aggregated phase of the binary solvent blend consisting of mesitylene and acetonitrile.…”

Numerous polymer semiconductor materials with alternating electron donorelectron acceptor (D-A) structures have attracted immense attention because they exhibit excellent semiconductor performance and solution processability. These materials can be used for the fabrication of various lightweight and flexible electronic devices. In this review, we provide a brief overview of the structural features and important properties of lactams whose performance can be enhanced by introducing an acceptor in the design of D-A-type polymer semiconductor materials. The focus is on polymer semiconductor materials with lactams in their structures, such as diketopyrrolo[3,4-c]pyrrole, naphthalene diimide, isoindigo, 2,2-bithiophene-3,3-dicarboximide, and thieno[3,4-c]pyrrole-4,6-dione. The recent advances made in the field in the last 3 years are discussed. In addition, the application of polymers for the fabrication of organic electronic devices and the progress in the field are discussed.

“…Solution processable π-conjugated semiconductors, a subset of organic materials, has progressively attracted much attention from both academic and industrial applications as the best candidate for lightweight, transparent, flexible electronic devices with less production cost for high throughput processing [1][2][3][4]. These materials have been fabricated as active organic layers in organic field-effect transistors (OFETs), organic photovoltaic (OPV) cells, and organic light emitting diodes (OLEDs) [5,6].…”

In this study, we reported the synthesis and characterization of a novel hyperbranched polymer (HBPs) tris[(4-phenyl)amino-alt-4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b’]dithiophene] (PTPABDT) composed of benzo[1,2-b:4,5-b’]dithiophene (BDT) and triphenyleamine (TPA) constituent subunits by A3 + B2 type Stille’s reaction. An estimated optical band gap of 1.69 eV with HOMO and LUMO levels of −5.29 eV and −3.60 eV, respectively, as well as a high thermal stability up to 398 °C were characterized for the synthesized polymer. PTPABDT fabricated as an encapsulated top gate/bottom contact (TGBC), organic field effect transistors (OFET) exhibited a p-type behavior with maximum field-effect mobility (µmax) and an on/off ratio of 1.22 × 10−3 cm2 V−1 s−1 and 7.47 × 102, respectively.

“…Similar to this work, Noh et al exploited other non-chlorinated solvents, such as acetophenone and mesitylene, to generate OFETs with comparable field-effect mobilities to that of dichlorobenzene. 29 Many other important works on the fabrication of organic electronics using green materials and processing, as well as new tool to identify and develop new green solvent systems for printed electronics have been summarized and reported in recent literature. 27,[30][31][32][33] Dendronized polymers are an interesting platform for the preparation of advanced semiconductors, particularly in biological applications and for the formation of nanoparticles.…”

Organic field-effect transistors processed by an environmentally friendly non-halogenated solvent blend

Abstract: Based on Hansen solubility parameter analysis, this study employed a non-halogenated binary solvent blend of mesitylene and acetophenone to closely mimic the efficiency of dichlorobenzene, for widely used conjugated polymers used for OFETs.
