High performance n-type organic transistors based on a distyrylthiophene derivative

Organic field-effect transistors (OFETs) based on a distyryl-thiophene (DST) derivative, 3′-(thiophene-2,5-diyl)bis(2-(3,5-bis(trifluoromethyl)phenyl)acrylonitrile (THIO-Y), were fabricated. Attributed to strong intermolecular interactions, dense molecular packing and appropriate energy level, OFETs based on a single crystal and thin film of THIO-Y showed electron mobilities as high as 0.16 and 0.03 cm2 V−1s−1, respectively.

{μ-N,N′-Bis[(E)-4-pyridylmethyl­idene]naphthalene-1,5-diamine}bis­[dichlorido(dimethyl sulfide)platinum(II)]

The title dinuclear platinum compound, [Pt2Cl4(C22H16N4)(C2H6S)2], with a long bridging bipyridyl-type ligand, is centrosymmetric and the PtII cation shows a slightly distorted square-planar coordination geometry. The Cl ligands are trans to each other, with a Cl—Pt—Cl angle of 178.83 (8)°. The pyridine ring forms a dihedral angle of 48.8 (2)° with the planar PtCl2SN unit. Within the molecule, the distance between Pt atoms is 20.262 (5) Å and the N⋯N separation between the terminal pyridyl rings is 16.23 (1)Å.
