Description

Adamantane compounds

The present invention relates to a novel adamantane compound, a production method thereof, a composition containing the compound, and a cured product using the compound, and more specifically, a photoresist for a semiconductor, an encapsulant for an optical semiconductor, an optical electronic member ( An adamantane compound that provides a cured product excellent in electrical characteristics such as optical properties such as transparency and light resistance, long-term heat resistance and dielectric constant, which is suitable as an optical waveguide, a lens for optical communication, an optical film, and the like, The present invention relates to a production method thereof, a composition containing the compound, and a cured product using the compound.

Adamantane has a structure in which four cyclohexane rings are condensed into a cage shape, is a highly symmetric and stable compound, and its derivative exhibits a unique function. It is known to be useful as a raw material for the above. For example, adamantane is used for an optical disk substrate, an optical fiber, a lens, or the like because of its excellent optical characteristics and heat resistance (see Patent Documents 1 and 2). In addition, an attempt has been made to use adamantane esters as a resin material for a photoresist by utilizing its acid sensitivity, dry etching resistance, ultraviolet transmittance, and the like (see Patent Document 3).

By the way, in recent years, in the field of electronic and optical materials, light sources using optical semiconductors such as high-definition, high viewing angle and high image quality of flat panel displays using liquid crystal or organic EL, and light emitting diodes (LEDs). High performance, improvement of optical and electronic parts, etc. are being promoted, such as development of high brightness, short wavelength and white color, and higher frequency of electronic circuits and development of circuits and communications using light.

Conventionally, acrylic resins having excellent transparency and light resistance have been widely used as resins for optical members. On the other hand, resins for optical members used in the field of optical and electronic equipment are required to have heat resistance and mechanical properties under mounting process on electronic substrates and high temperature operation, and epoxy resins are often used. . In recent years, many techniques have been known for the purpose of improving the performance of these resins. For example, to improve the heat resistance of acrylic resins, cross-linked acrylic resins using multiple acrylate monomers have been studied, and in particular, cured products of alicyclic acrylates have high glass transition temperatures and low cure shrinkage and moisture absorption. Therefore, technical development relating to an acrylate copolymer containing an alicyclic acrylate has been performed (for example, see Patent Document 4). Also disclosed is a composition comprising a polyfunctional (meth) acrylate having a (meth) acrylic acid ester having an alicyclic hydrocarbon group having 5 to 22 carbon atoms in the ester portion and an alkylene oxide, which is used for an optical adhesive or the like. (For example, refer to Patent Document 5). However, although the composition satisfies the heat resistance at the time of mounting as an adhesive, the composition has insufficient heat resistance and mechanical properties.

Thus, in order to cope with the recent high performance of optical and electronic components, further material development is necessary, and the use of adamantane is expected. For example, Patent Document 6 discloses a glycidyloxy group-containing adamantane compound and an adamantyl group-containing epoxy-modified acrylate. However, the glycidyloxy group-containing adamantane compound has a problem of poor processability due to low solubility in acid anhydrides. Further, the adamantyl group-containing epoxy-modified acrylate is a compound having a hydroxyl group, and the cured product has a problem that its use is limited because of its water absorption.

The present invention has been made in view of the above circumstances, and includes a semiconductor photoresist, an optical semiconductor sealing agent, an optical electronic member (such as an optical waveguide, an optical communication lens, and an optical film), and an adamantane compound suitable as an adhesive thereof. In other words, it is an adamantane compound with high solubility in acid anhydrides, and has excellent optical properties such as transparency and light resistance, long-term heat resistance, electrical properties such as dielectric constant, and low cured product.
