Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention is generally related to a compound containing (pentaphenyl)phenyl group, and more particularly to a compound containing (pentaphenyl)phenyl group, used as an organic display material, and its polymeric derivative and a method for forming the same.

[0003] 2. Description of the Prior Art

[0004] Organic light emitting diode displays, also known as organic electroluminescent displays (referred to as “OEL display”) have advantages of self-emitting, quick response time, wide viewing angle, simple fabricating processes, and being flexible. Luminance mechanism of organic electroluminescence is similar to that of inorganic light emitting diodes. Generally, organic light emitting diodes can be divided into two categories: small molecule organic light emitting diodes and polymer organic light emitting diodes. For small molecule organic light emitting diodes, small molecule dyes or pigments are the major compositi...
