Nanoscale Archimedean Tilings Formed by 3-Miktoarm Star Terpolymer Thin FilmsFacility for Printed Organic Electronics

3‐Miktoarm star terpolymer architecture (3 µ ‐ABC), consisting of three dissimilar polymer chains, A, B, and C connected at a junction point, provides a unique opportunity in the design of complex nanoscale patterns such as Archimedean tilings that are not accessible from linear ABC terpolymers. In this work, the synthesis and the self‐assembly of 3‐miktoarm star terpolymers, namely,...

Micellar-Mediated Block Copolymer Ordering Dynamics Revealed by In-Situ Grazing Incidence Small-Angle X-ray Scattering during Spin CoatingFacility for Printed Organic Electronics

Spin coating is one of the most versatile methods to generate nanostructured block copolymer (BCP) thin films which are highly desired for many applications such as nanolithography or organic electronics. The self‐assembly pathways through phase separation, both in solvent and in bulk, strongly influence the final BCP structure obtained after spin coating. As a demonstration, the formation of...

Enhancing the ferroelectric performance of P(VDF-co-TrFE) through modulation of crystallinity and polymorphismFacility for Printed Organic Electronics

The functional properties of P(VDF- co -TrFE) are strongly dependent on its structure, which, in turn, depends on processing conditions applied. In this work we investigate the P(VDF- co -TrFE) processing-structure-function relationships, in order to find the thermal conditions that result in optimum ferroelectric performance in thin film configuration. Our results show that annealing...

Synthesis of Bioinspired Curcuminoid Small Molecules for Solution-Processed Organic Solar Cells with High Open-Circuit VoltageFacility for Printed Organic Electronics

Borondifluoride complexes of curcuminoid derivatives end-capped with triphenylamine groups were designed for solution-processed bulk-heterojunction organic solar cells. They were obtained very simply in a one-pot synthesis from cheap building blocks. Compared to push–pull systems based on borondifluoride complexes of hydroxychalcones, curcuminoids present the donor–acceptor–donor electronic...

Aqueous PCDTBT:PC71BM Photovoltaic Inks Made by NanoprecipitationFacility for Printed Organic Electronics

The fabrication of organic solar cells from aqueous dispersions of photoactive nanoparticles has recently attracted the interest of the photovoltaic community, since these dispersions offer an eco‐friendly solution for the fabrication of solar cells, avoiding the use of toxic solvents. In this work, aqueous dispersions of pure...

Photoactive donor-acceptor composite nanoparticles dispersed in waterFacility for Printed Organic Electronics

A major issue that inhibits the large-scale fabrication of organic solar modules is the use of chlorinated solvents considered to be toxic and hazardous. In this work, composite particles of poly[ N -9′-heptadecanyl-2,7-carbazole- alt -5,5-(4,7-di-2-thienyl-2′,1′,3′-benzothiadiazole] (PCDTBT) and [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) were obtained in water from a versatile and a...
