“…Although polymer‐based OFETs are easily processed using solution‐based methods, carrier mobilities in polymer devices are limited due to poor polymer packing and defects on a macroscopic scale resulting from weak intermolecular van der Waals forces 2. Several approaches to improve the field‐effect mobilities of OFETs have been developed for use in single‐crystalline films,3 vacuum‐deposited films,4 and polymer/small‐molecule blends;5 however, these film formation methods are difficult to control and cannot be adapted to the mass production of flexible, low‐cost, and large‐area devices. A less complex alternative is presented by the use of solution‐processed homogeneous polymer semiconductors 6.…”

A new polymeric semiconductor, PDPPDTSE, is reported which is composed of a diketopyrrolopyrrole moiety and selenophenylene vinylene selenophene, with a high field-effect mobility achieved through intermolecular donor-acceptor interactions. The field-effect mobility of OFET devices based on PDPPDTSE by spin-casting is 4.97 cm(2) V(-1) s(-1) , which is higher than predecessor polymeric semiconductors.

“…In this process, a limit in the use of traditional inorganic materials such as silicon was reached, because it loses its properties at nanoscopic conditions. In this context, a new generation of molecular materials has emerged derived from new areas of scientific research to replace the traditional inorganic materials …”

In this work, the adsorption of a type of cruciform system integrated by an anthracene central part and two side chains with a pyridine-vinyl structure (DPAC) was studied on plasmonic nanoparticles of silver and gold. The adsorption was investigated by surface-enhanced Raman scattering, which reveals very valuable information about both the interaction mechanism and the molecular orientation. The highest Raman enhancement was measured on Ag nanostars due to the combination of gaps and tips in these nanostructures. The changes observed in the surface-enhanced Raman scattering spectra indicate that the adsorption of DPAC on the metal is bifunctional in the case of Ag and Au nanoparticles. Considering that the Raman signals enhancement is several orders of magnitude higher in gaps in relation to regions out of these areas, it is estimated that the enhancement ability of DPAC in Ag nanostars is so high that it allows the detection of a concentration close to pM.

“…Organic materials dominate in flexible electronics research due to the convenient processing methodologies. Importantly, organic devices and circuits have been fabricated over large area flexible materials through low temperature printing or additive techniques [4][5][6]. However, organic electronics present some drawbacks such as rapid switching time, poor device stability and low device density.…”

Abstract-Inorganic nanomaterials such as nanowires (NWs) and nanotubes (NTs) are explored for future flexible electronics applications due to their attributes such as high aspect ratio, enhanced surface-to-volume ratio, prominent mobility and ability to integrate on non-conventional substrates. Device performance of semiconducting NWs are demonstrated to be superior compared to the organic counterparts. Among the synthesis methods, bottom-up vapour-liquid-solid (VLS) growth mechanism playing central role for preparing wide variety of high crystal quality semiconducting NWs. However, the high temperature synthesis process prevents fabrication of NW devices directly over flexible substrates which imply the investigation of efficient transfer techniques such as dry contact printing and electric field assisted assembly. Currently, many efforts are directed to study the integration techniques of NWs from growth substrates to non-conventional receiver substrates and parameters such as transfer-yield, alignment and density. These efforts will help to utlilize NWs as building blocks in future flexible electronic devices and circuits. This work focuses on VLS growth of semiconducting NWs and their transfer-printing over large area substrate to fabricate flexible electronics.
