Title:
CHARGE-TRANSPORTING ORGANIC MATERIAL CONTAINING COMPOUND HAVING 1,4-DITHIIN RING
Document Type and Number:
WIPO Patent Application WO/2005/043962
Kind Code:
A1
Abstract:
Disclosed is a charge-transporting organic material which contains a compound with a 1,4-dithiin ring which is represented by the formula (1) below. By using a thin film made of such a organic material in a small-molecule organic electroluminescent device (OLED) or a polymer organic electroluminescent device (PLED), there can be improved EL device characteristics such as low driving voltage and high luminous efficiency. Meanwhile, a charge-transporting varnish containing the compound with a 1,4-dithiin ring represented by the formula (1) below has good processing properties. Consequently, a thin film made from such a vanish has high charge-transporting characteristics and thus is useful when applied to protective films for capacitor electrodes, antistatic films, solar cells or fuel cells.
