High hole-mobility of rrP3HT in organic field-effect transistors using low-polarity polyurethane as gate dielectric

10.1016/j.orgel.2018.03.033

2018-03-23

We report unusually high charge carrier mobilities for regioregular poly(3-hexyltiophene) (rrP3HT) in organic field-effect transistors (OFETs) using polyurethane (PU) as dielectric layer. Our devices display hole mobilities up to 1.37 cm2/V in the saturation ...

A thermally cross-linked hole-transporting film with the remarkable solvent resistance for solution-processed OLEDs

2018-03-23

In this work, we report a systematic study of the properties of the thermal cross-linkable triarylamine based hole-transporting material (HTM) N,N′-di-p-tolyl-N,N′-bis(4-vinylphenyl)-[1,1′-biphenyl]-4,4′-diamine (V-p-TPD) and the distinctive nature of its cro...

Solution processed blue-emitting and hole-transporting materials from truxene-carbazole-pyrene triads

10.1016/j.orgel.2018.03.035

2018-03-23

A new series of truxene derivatives containing different numbers of dipyrenylcarbazole substituents are prepared and evaluated as emissive and hole-transporting layers in electroluminescent devices. The compounds are synthesized from Cu-catalyzed C-N coupling...

Cation discrimination in organic electrochemical transistors by dual frequency sensing

10.1016/j.orgel.2018.03.020

2018-03-23

In this work, we propose a strategy to sense quantitatively and specifically cations, out of a single organic electrochemical transistor (OECT) device exposed to an electrolyte. From the systematic study of six different chloride salts over 12 different conce...

Transparent electrodes based on ultrathin/ultra smooth Cu films produced through atomic layer deposition as new ITO-free organic light-emitting devices

10.1016/j.orgel.2018.03.036

2018-03-21

Ultrathin and continuous metallic films with mechanical robustness, high electrical conductivity and high elevated optical transparency are considered as ideal alternatives of the ITO electrodes. However, continuous and smooth morphology have not yet been sim...

Efficient management of excitons in red and white organic light-emitting diodes by employing blue thermally activated delayed fluorescent emitter based acridine/sulfone derivative as the host

2018-03-20

Highly efficient red and white organic light-emitting diodes (OLEDs) employing blue thermally activated delayed fluorescent (TADF) emitter of mSOAD based acridine/sulfone derivative as the host are realized by efficient management for singlet and triplet exci...

Improved performance of non-fullerene polymer solar cells using wide-bandgap random terpolymers

2018-03-20

A series of wide-bandgap random terpolymers were designed and synthesized for application as the donor polymers in non-fullerene polymer solar cells. The benzodithiophene (BDT) derivatives with phenyl and thienyl conjugated side chains (denoted as BDTP and BD...

A dual-wavelength polymer random laser with the step-type cavity

10.1016/j.orgel.2018.03.032

2018-03-20

A dual-wavelength random laser of polymer film is fabricated by a spincoating method, and the dual cavities of step type are prepared on a silica substrate. The random microstructure forms due to the phase separation in the fabrication process, and provides a...

Solvent effects on excited state intramolecular proton transfer mechanism in 4-(N,N-dimethylamino)-3-hydroxyflavone
