In this forum article, we discuss selected recent contributions to the field of nonplanar aromatic molecules, focusing on properties that arise from molecular curvature. Ten reports are highlighted demonstrate diverse applications curved aromatics in materials science would not be achieved by their planar congeners. Graphene is a carbon allotrope comprising single, flat layer hexagonally arrang...

Identifying specific microstructure-property relationships in polycrystalline organic semiconductor films is a key goal for the field of organic electronics. Using transverse shear microscopy, we have established for the first time the presence of both epitaxial and non-epitaxial domains in ultrathin polycrystalline layers of pentacene grown on SiO2. The microstructure of pentacene films is par...

Diketopyrrolopyrrole (DPP) is one of the most promising building blocks for constructing polymer semiconductors with high charge-carrier mobilities in organic field-effect transistors (OFETs). In this study, a novel DPP-based conjugated polymer, PDPPy-BDD, was designed and synthesized. The ambipolar transistor characteristics were realized average hole electron 3.5 × 10–3 3.07 10–2 cm2 V−1 s−1,...

The major advantages of organic electronics are their solution processability and unique optoelectronic performance. long-range ordered single-crystal semiconductor provides the best device performance, as it guarantees efficient charge injection transport minimum defect states. Thus, a facial solution-printing-based method to fabricate devices circuits is great importance development electroni...

A large effort is devoted to the research of new computing paradigms associated to innovative nanotechnologies that should complement and/or propose alternative solutions to the classical Von Neumann/CMOS association. Among various propositions, Spiking Neural Network (SNN) seems a valid candidate. (i) In terms of functions, SNN using relative spike timing for information coding are deemed to b...
