Organic Semiconductive Polymer: Verazol^® HT Series (P3HT)

The Verazol HT series adopts organic semiconductor P3HT (poly (3-hexylthiophene)) with increased molecular weight control based on Soken's unique polymerization technology. The series features low cost due to an efficient manufacturing process, in addition to molecular weight control and a high degree of regioregularity.

All grades feature regioregularity of 97% or higher. In addition to the standard Mw 40 to 70 K and Mw 90 to 130 K, an extra high molecular weight grade of Mw 400 to 700K is available thanks to the increased control over molecular weight.

Grade	Mw	Mw/Mn	Regio-regularity
Verazol^® HT-005	40～70K	1.5～2.5	≧97%
Verazol^® HT-010	90～130K	1.5～3.0	≧98%
Verazol^® HT-030	400～700K	2.0～3.5	≧98%

Applications

Applications include organic photovoltaics (OPV) and organic field-effective transistors (OFET). For OPV applications, in particular, structural control of bulk heterojunction layers using different grades is expected.

Organic photovoltaics are thin and lightweight, drawing considerable attention as a next-generation solar cell to replace the existing inorganic types.

Example of display device using organic transistor

Organic transistors can be manufactured at low temperatures using printing techniques, and are receiving well-deserved attention as next-generation transistors. They are expected to be used in devices in ways that are difficult to achieve with existing inorganic transistors.
Applications: IC tags, sensors, organic EL devices, etc.
