Fluorine-containing diethynyl aryl derivatives (1–5), in which three aromatic rings were connected together with rigid acetylenic linkages, were synthesized for n-channel organic field-effect transistors. The field-effect electron mobility of the thin film of 2 exhibited 3.4×10−3 cm2 V−1 s−1.

Selective Hg2+-binding of click-derived triazole-based amphiphiles can lead to the formation of nanostructures, even below CMCs, which are determined by the stoichiometry of amphiphile–Hg2+ complexes affecting the interfacial curvature.

of new materials with unconventional photophysical behavior. In this work, a family of diphosphine ligands PPh2–PAH–PPh2 with variable polyaromatic hydrocarbon (PAH) spacers (PAH = 9,10-anthracene L1, 1,4-naphthalene L2, 2,6-naphthalene L3, and their diethynyl congeners L4–L6) were employed to prepare gold(I) complexes (RC2Au)PPh2–PAH–PPh2(AuC2R) (1–22), containing a selection of alkynyl groups. Investigation
New luminophores having different aryl nuclei and propynones moieties have been obtained via sonogashira reactions. Their optical properties were evaluated and indicated that carbonylgroups are responsible for significant bathochromic effects and high stokes shifts. The insertion of -ome groups on the central benzene unit gives to the fluorophore high optical efficiency when homogeneously dispersed
