Oxytocin detection at ppt level in human saliva by an extended-gate-type organic field-effect transistor.

Herein, we report an extended-gate-type organic field-effect transistor (OFET) sensor for oxytocin. The fabricated OFET-based immunosensor has successfully detected oxytocin at a ppt level in human saliva with high recovery rates (96-102%). We believe our sensor would pave the way for the realization of portable sensors for healthcare monitoring.

High-performance solution-processable N-shaped organic semiconducting materials with stabilized crystal phase.

N-shaped organic semiconductors are synthesized via four steps from a readily available starting material. Such semiconductors exhibit preferable ionization potential for p-type operation, thermally stable crystalline phase over 200 °C, and high carrier mobility up to 16 cm(2) V(-1) s(-1) (12.1 cm(2) V(-1) s(-1) on average) with small threshold voltages in solution-crystallized field-effect transistors.

Furan fused V-shaped organic semiconducting materials with high emission and high mobility.

We report a facile synthetic protocol for preparation of dinaphtho[2,3-b:2',3'-d]furan (DNF-V) derivatives. DNF-V derivatives showed high emissive behaviour in solid. A solution-crystallized transistor based on alkylated DNF-V derivatives showed an excellent carrier mobility of up to 1.3 cm(2) V(-1) s(-1), thereby proving to be a new solution-processable active organic semiconductor with high emission and high mobility.

V-shaped organic semiconductors with solution processability, high mobility, and high thermal durability.

V-shaped organic semiconductors have been designed and synthesized via a large-scale applicable synthetic route. Solution-crystallized films based on such molecules have demonstrated high-performance transistor properties with maximum mobilities of up to 9.5 cm(2) V(-1) s(-1) as well as pronounced thermal durability of up to 150 °C inherent in the V-shaped cores.
