Indolestyryl compounds and use thereof for a high density recording media and method for fabricating the same. The indolestyryl compounds exhibit strong absorbance in the visible light region (400&#x2dc;700 nm) of the spectrum, resistance to heat and light, high light sensitivity, and excellent solubility, resulting from their special chemical configuration. Furthermore, the indolestyryl compounds can be used as recording layer materials in high density recording media for matching a reading laser wavelength and enhancing the reflective index and carrier-to-noise ratio (CNR) of the high density recording media. Accordingly, the recording sensitivity and the readout characteristics of high density recording media comprising the indolestyryl compound according to the present invention can be improved.

Indolestyryl compound for use in recording media and method for fabrication thereof

A compound used as storage medium of high-density optical disc is disclosed, which has structure represented as following formula:wherein each A, A, A, and Aindependently is selectively substituted aryl or heteroaryl, said aryl or heteroaryl is selectively substituted by one or multiple functional groups; Rand Rindependently is H, halogen, alkyl or aryl; B is Ar orn is an integral ranging from 1 to 4; and n' is an integral ranging from 0 to 4.

Compounds for recording media and high-density optical recording media thereof

The invention discloses new benzoindole styryl compounds and its use for a high-density optical recording medium. The invention uses the dyes of the new benzoindole styryl compounds to form the recording layer of high-density recording media. The new benzoindole styryl compounds are easy to prepare and purify, so they are cheaper when comparing to the compounds generally used in high-density optical recording media. The benzoindole styryl compounds has a maximum absorption for the light wavelength in the range of 500 nanometers to 700 nanometers. The benzoindole styryl compounds also have high sensitivity and chemical stability for light and heat. Using the new benzoindole styryl compounds to form a high-density optical recording medium can match up with the short-wavelength laser beam for high-density optical recording media and have the advantage of a stable quality.
