Description
Technical field
The present invention relates to siloxane precursor body and synthetic method thereof that a class contains azobenzene dye.
Background technology
Because nonlinear optical material has application prospect greatly at aspects such as full optical communication, photometry calculation and optical information processing, just becomes the hot fields that the countries in the world scientist competitively studies so seek the nonlinear optical material of stability and high efficiency.Mineral crystal is the quasi-nonlinear optical material that people study the earliest and use, though the crystal technique of these materials reaches its maturity, but still exist tangible weak point: as cost an arm and a leg, be easy to damage, and can only use monocrystal material work, be difficult to realize that optics is integrated.Therefore, since the seventies in last century, people have begun exploration organic and the polymkeric substance nonlinear optical material.This class material has the nonlinear optical coefficients than the high 1-2 of a mineral crystal order of magnitude, and big optical damage threshold (can reach GW/cm
2), the polytropy of series of advantages, especially organic molecular structures such as (subpicosecond are to femtosecond) of ultrafast time of response makes people can realize that molecule cuts out and molecular designing by the understanding to its structure-performance relation, thereby satisfies the requirement of device practicability.
The proposition of initial stage eighties polar polymer notion and successful practice have worldwide started the research boom of organic non linear optical material, indicate that the polymkeric substance nonlinear optical material has entered the study period with practical prospect.The beginning of the nineties, in view of research work in the world than quantum jump, many scientists foretell that polar polymer is expected to obtain at first practicability, the electrostrictive polymer photomodulator also will come into the market in several years." chemistry and Engineering News Record " (C﹠amp of the U.S.; EN) magazine also is title and has done detailed introduction with " Devices based onelectro-optic polymers begin to enter market-place " at front cover.Yet what have no need for reticence is, because problems such as low, repeatable difference of the thermostability that the intrinsic factor of organic materials causes and loss of light propagation are big still fail to solve fully, really do not develop a kind of polymeric system that can satisfy the practical requirement of all devices simultaneously so far.Therefore, after the hot topic that has experienced initial more than ten years, the research of polar polymer is just entering relative low tide period at present.
The inorganic-organic hybridization material of sol-gel method preparation then is a kind of advanced composite material that occurs in recent years, it forms the unorganic glass network by alkoxide hydrolysis at ambient temperature, the polycondensation of Si, Al, Zr or Ti, and organic constituent then combines with inorganic matrix by the mode of mixing or key connects.Organic-inorganic hybridized non-linear optical material by this method preparation has been broken through traditional inorganic, the boundary of organic non linear optical material, organic non-linear molecule and inorganic matrix are combined together on molecular level, not only have concurrently inorganic, both performance advantages of organic materials, and can realize the compound and cooperate optimization of function, be considered to one of the novel non-linearity optical material that obtains practical application that most possibly takes the lead in, thereby various countries scientists' research interest and research enthusiasm have been attracted, wherein, structure is clear and definite, the inorganic organic hybrid nonlinear optical material of the chemical bond-linking type of stable performance gets most of the attention especially.Though the research of this respect has the history of more than ten years, but design, synthesize the siloxane dye that is connected with various function chromophore molecules and still have bigger challenge, and this prepares indispensable key link in the inorganic organic hybrid nonlinear optical material process of chemical bond-linking type just.
" pushing away-La " the type azobenzene dye is a class has electron donor(ED) and electron acceptor(EA) simultaneously at the two key two ends of azo chromophore molecule.Because the two keys of azo N=N provide excellent electron channel, make the conjugated electrons in the molecule have very big flowability, electronics is easy to migration under electric field action, is to have low π-π
*The energy system of excited electronic state.Have higher single order hyperpolarizability and thermostability owing to this quasi-molecule in recent years, and tangible intramolecular charge transfer organization feature, it is synthetic to be widely used in organic design with the polymkeric substance nonlinear optical material, and has obtained a large amount of achievements.But it is synthetic and correlative study is still rare to utilize this class dyestuff to carry out the design of siloxane precursor body.
Summary of the invention
The object of the present invention is to provide a class to contain the siloxane precursor body and the synthetic method thereof of azobenzene dye.This compounds is not only synthetic convenient, and purifying is simple, can be used as the novel non-linearity optical material and obtains practical application in fields such as Electro-optical Modulation, photoswitch and phase conjugations.
