TL;DR: In this paper, a ladder-type electron-deficient core-based central fused ring (Dithienothiophen[3.2-b]- pyrrolobenzothiadiazole) with a benzothiadiadiazoles (BT) core was proposed to fine-tune its absorption and electron affinity.
Journal ArticleDOI
Control of color and efficiency of light-emitting diodes based on polyfluorenes blended with hole-transporting molecules

TL;DR: In this article, a low-molecular-weight hole-transporting molecules (HTM) with different oxidation potentials were added to the polyfluorene emission layer of single-layer light-emitting diodes.
Journal ArticleDOI
High-Performance Single Crystal Organic Field-Effect Transistors Based on Two Dithiophene-Tetrathiafulvalene (DT-TTF) Polymorphs

TL;DR: The performance of solution-prepared single crystal OFETs based on two different polymorphs of dithiophene-tetrathiafulvalene, which were investigated by confocal Raman spectroscopy and X-ray diffraction, show that both polymorphs exhibited excellent device performance.
Journal ArticleDOI
Conductive polymer: reticulate doping with charge-transfer complex
TL;DR: In this paper, a new method of introducing microcrystalline charge transfer (CT) complexes into polymers is described, which consists of growing microcrystals during film casting.
Journal ArticleDOI
