Abstract

The invention discloses a kind of dibenzo tetraaza (14) annulene compounds, of which a preparation method and the application in the aspect of a optical recording media. The structural general formula of the compounds is indicated as formula I. The dibenzo tetraaza (14) annulene materials which are provided by the invention have the advantages of high luminous sensitivity, good thermal stability (TG decomposition temperature is more than 250 DEG C), high solubility, easy dissolution and good crystallization resistance. The compounds can be dissolved in the ether solvent, and the solubility in the alcohol or in the ether solvent can be more than 6 percent. The light stabilizer does not need to be added during the production process, only such materials are used alone. The usage of the dibenzo tetraaza (14) annulene materials which are provided by the invention for the optical disk production can not only significantly reduce the production cost of the optical disks, but also greatly improve the recording performance of the disks at the same time of meeting the requirement of current BD-R and HD DVD-R optical disks on the recording media.

Description

technical field [0001] The invention relates to a class of annulene compounds and a preparation method and application thereof, in particular to dibenzotetraaza[14]annulene compounds. Background technique [0002] In recent years, with the rapid development of the information industry, the traditional storage methods have undergone revolutionary changes. The development and progress of the society has led to the rapid expansion of the amount of information. How to effectively store, manage and utilize various information has become an important issue in people's daily work and life. Due to the advantages of high storage density, high fidelity, high definition, long life, and fast data access speed, optical discs have been widely used in production and office automation, education, scientific research, document storage and retrieval, advertising, software , audio-visual entertainment and other fields. Originally, the content of the CD disc was copied in when the disc was pr...
