We have synthesized two novel dicyanovinylene-substituted DPP–oligothiophene semiconductors, DPP-4T-2DCV and 2DPP-6T-2DCV. In these materials, the combination of an extended oligothiophene conjugated skeleton with strong electron-withdrawing DPP–dicyanovinylene groups results in semiconductors exhibiting ambipolar TFT response reasonably balanced electron hole mobilities up to 0.16 cm2 V−1 s−1 0.02 s−1, respectively. Furthermore, no thermal annealing is necessary afford high mobility, making...
The reaction of equimolecular amounts a nitrile and triflic anhydride or acid at low temperature produces an intermediate nitrilium salt that subsequently reacts with 2 equiv different higher to form 2,4-disusbstituted-6-substituted 1,3,5-triazines in moderate good yields. This synthetic procedure has also been applied the preparation 1,3,5-triazine having three substituents. results are explained terms mechanism based on relative stability salts formed through reversible pathway. formation...
Star-shaped nanographenes (SNGs) are large monodisperse polycyclic aromatic hydrocarbons that larger than a nanometer and have shown lot of promise in wide range applications including electronics, energy conversion, sensing. Herein, we report new family giant star-shaped N-doped with diameters up to 6.5 nm. Furthermore, the high solubility this SNG neutral organic solvents at room temperature allowed complete structural, optoelectronic, electrochemical characterisation, which together...
Two-dimensional fused aromatic networks (2D FANs) have emerged as a highly versatile alternative to holey graphene. The synthesis of 2D FANs with increasingly larger lattice dimensions will enable new application perspectives. However, the analogues is mostly limited by lack appropriate monomers and methods. Herein, we describe synthesis, characterisation properties an expanded FAN 90-ring hexagons, which exceed largest lattices reported date.

Abstract The synthesis, characterization, and optical properties of a novel star‐shaped oligothiophene with central rigid trithienobenzene (BTT) core diketopyrrolopyrrole (DPP) units are reported compared homologous linear systems based on the benzodithiophene (BDT) naphthodithiophene (NDT) end capped DPPs. This comparison is aimed at elucidating effect configuration versus conformation electrical properties. Electronic vibrational spectroscopies, together transient absorption spectroscopy,...
Herein, we report the synthesis of mechanically interlocked nitrogenated nanographenes. These systems have been obtained by clipping different tetralactam macrocycles around a 1.9 nm dumbbell-shaped nanographene. Thermal, optoelectronic, and electrochemical characterization nanographenes evidence enhanced thermal photochemical stability, also absorption emission properties that vary with structure macrocycle.
Which effect directs supramolecular packing? π–π stabilizing interactions between two NDI units or dipole–dipole couplings?
Three new hexaazatriphenylene (HAT)-based electron-accepting molecules with octupolar disc-like symmetry that combine the HAT core six branches of electron-donor thiophenes in two modalities have been synthesized: (i) donor and bithiophenes delineating a six-donor-to-one-acceptor (6–1) profile (ii) donor–acceptor configuring 6–6–1 acceptor–donor–acceptor triad. The 6-fold accumulation donors acceptors periphery is expected to tune molecular electronic optical properties. An exhaustive...
