| Summary: | 碩士 === 朝陽科技大學 === 應用化學系碩士班 === 101 === PART I :
In recent years, people attach great importance to safety of agricultural
products. Because of non-toxic, specificity, biological activity, persistence, easy
to manufacture, highly compatibility, no drug resistance and low cost,
pheromones have obvious advantages compared to traditional pesticides.
Because of abusing of pesticides may cause resistance and environmental
pollutions, more and more alternative methods have been studied, pheromones
are the one of important alternative.
To synthesis sex pheromones, we use diol compound as the starting
reactant to synthesis different types of pheromones by Wittig Reaction. We have
successfully synthesized the Asian corn borers, Tobacco cutworm and Orange
spotted shoot moth. This method can be used to produce commercial production
easily. The structure of sex pheromones of Asia corn borers have cis-trans
isomers, with different ratio, we can figure the best attractants effect out. The
first step of this researching use Wittig Reaction to synthesis 93% Z-form
product, and then use isomerization to raise the ratio of E-form product to 70%
to get the most effective attractant, where is Z-form:E-form = 3:1.
PART II :
In recent years, photochromic dyes are mainly used in optical memory. We
can use it to combine with a variety of substrates and applications to be widely
used in various fields, such as photochromic sunglasses, color filter,
photochromic fiber, ultraviolet indicator and other technology industries. Among
many applications in biological detection needs highly precision, researching of
development and application of combining with functional dye in the biological
testing has been take more attention.
Our laboratory has successfully done many studies of organic
photochromic dyes Spiropyrans series that explore from nature. Currently, we
focus on the application of photochromic dyes combination with L-tyrosine and
intensive study on the combined with amino acids and photochromic dyes.
