Provided is an optical data storage medium comprising a chromophore/polymer composition information layer, wherein the chromophore is chemically bound or coordinated with the polymer. The chromophore is an organo macrocyclic chromophore containing a constitutent metal atom, and preferably a central metal atom, with the chromophore being coordinated to the polymer through the metal atom. As a result, the chromophore/polymer material has excellent film-forming properties so that the medium can be readily and efficiently manufactured. As well, the resulting information layer offers excellent thermomechanical properties and exhibits excellent absorption properties, all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in conventional dy/polymer mixtures is also overcome.
本发明提供了一种光学数据存储介质,该介质包含发色团/聚合物组成的信息层,其中发色团与聚合物化学结合或配位。发色团是一种有机大环发色团,含有一个构成金属原子,最好是一个中心金属原子,发色团通过金属原子与聚合物配位。因此,发色团/聚合物材料具有优异的成膜性能,从而可以方便、高效地制造介质。此外,由此产生的信息层还具有出色的热机械性能和优异的吸收性能,所有这些都只需一种单组分材料即可实现。通过使用单组分材料,还克服了传统染料/聚合物混合物中经常遇到的染料/聚合物相分离的问题。
