| 摘要: | 本研究以2-甲基為原料，與鹵烷類進行加成反應，主要有 碘代甲烷、溴丁烷、1,2-二溴乙烷與1,5 二溴戊烷，其中碘代甲烷與 溴丁烷為進行單邊加成反應，而1,2-二溴乙烷與1,5-二溴戊烷則為 進行雙邊加成反應。反應所形成之鹵鹽化合物為初步原料，再與 芳香醛類與乙氧基類進行縮合反應，而得延伸雙鍵共軛系之化合物。 目的為藉由改變共軛雙鍵的數目，來達成波長至700 nm 以上的 化合物，使其應用在光電染料上。 並針對這些化合物作其反應條件的探討，使其能達成最佳的產 率，並選擇適合的溶劑來進行再結晶，使產物更為精製。 討論各類化合物之相同性與差異性，並藉由UV/VIS 吸收光譜、 IR 光譜與元素分析來初步判斷產物是否為所需要的。 In this research, we took 2-methylquinoline as raw material, to proceed the addition reactions with haloalkanes, including the iodomethane、butylbromide、1,2-dibromoethane and 1,5-dibromopentane.The iodomethane and butylbromide were taken to proceed unilateral addition reactions, and 1,2-dibromoethane and 1,5-dibromopentane were taken to proceed bilateral addition reactions. The quinolinium alkaline soil chemical compound formed from the reaction was taken as rudimentary material. Then it was taken with triethyl orthoformate、4-(dimethylamino)benzaldehyde and 4-dimethylaminocinnamaldehyde to proceed condensed reactions to get extend double bond conjugated chemical compound. The object of this research is to change the number of conjugated double boud , and to achieve the chemical compounds of wavelength which is more than 700 nm. Then it can be applied to the dye of photoelectron. With the research of the reaction condition of the chemical compound, we can get a optimum condition to achieve best output yield, and with choosing a fit solvent to proceed recrystallization, the products will be more pure. We will discuss the consistence and difference of each kind of chemical compound, and determine, if the products is that we need by UV/VIS、IR and ultimate analysis. |
