Dear Readers, Welcome to the latest issue of The Magazine
Organic semiconductors have been receiving much attention as promising materials for “printed electronics” owing to their flexibility and solubility. TCI offers several special reagents of guaranteed very high-quality for these purposes, including typical and cutting-edge semiconducting materials utilized for organic field effect transistors (OFET), organic photovoltaics (OPV), or organic electroluminescence devices (OLED).
rnEvery batch of the reagents are uniquely analysed against our high purity and quality standards by in-house preparation of OFET devices, and tested for FET mobility. We continue to recognize and value the real performance of our materials research products as a quality standard, wherein conventional analytical methods are not accurate enough to reveal performance deficiencies due to impurities.

Organic Transistor (OFET) Materials
One functional parameter for evaluation of an organic semiconductor is mobility (μ) that shows how fast holes or electrons move in the semiconducting layer. We need an organic material with high mobility for highly drivable electronic circuits. The mobility can be measured from an organic field-effect transistor (OFET). There are TOF and TRMC methods for the measurement. The OFET can be fabricated by an organic semiconductor layer, insulating layer, source, drain and gate electrodes. In addition to the mobility value, we can determine fundamental OFET characteristics such as minimum drive voltage and drive stability. To learn more, click here
Organic Light-Emitting Diode (OLED) Materials
A practical OLED device further requires excellent heat-resistance and durability. Many hole transport materials based on triphenylamine derivatives (TPD) are widely usable, because they are heat-resistant and amorphous. In addition to the TPDs, oxadiazole derivatives (PBD) having an electron transport property, Alq3 as a host material, and blue emissive distylyl derivatives are fundamental materials for amorphous OLED devices.
