The Synthesis And Test Of Bodipy New Fluorescent And Thiophene Compounds Organic Functionl Materials

Boron dipyrromethene dye(BODIPY) have exceptional photochemistry and phtophysical properties,such as high molar extinction coefficients, high ptotostability, high quantum yields. Photochromiccompounds which have unique advantages, have been widely used in interred industries. Currently theirpotential application values also get more and more people’s attention. Diarylethene is one of mostpromising photochromic materials, which have good solubility, good ptotostability and good fatiguedurability. Triphenylamine have the typical rigid structure and good fluorophore. So the study of itsderivatives is of high research value.Based on the unique features of the above compounds, in chapter two, we synthesis a series of newfluorescent dyes through typical Sonogashira reaction, which is centered on fluorophore nuclear, andconnecting the BODIPY, naphthalimide, triangle thiophene light-induced discoloration groups and otherfluorophores. In addition, we mensurates and analyzes their UV absorption, fluorescence emissionspectroscopy and electrochemistry.In chapter three, five dendritic thiophene compounds were synthesized through the Sonogashirareaction and the Suzuki reaction centred on triphenylamine nucleus. It is sure that the two compounds havegood fluorescence intensity and fluorescence intensity according to the measurement and analysis of UVabsorption spectroscopy and electrochemical. The products that have both phtochromic properties andfluorescent intensity are the ideal targets that we intend to get.In chapter four, a series of dumbbell-shaped photochromic compounds were synthesized throughSonogashira reaction and Stille cross-coupling reaction. We mensurates and analyzes their UV absorption,fluorescence emission spectroscopy and electrochemistry. And creatively synthesizes Thiophene-acetylenecoupling products. By determination, the product is of good photochromic properties, which supplies newsynthesis ideas for us.In chapter five，three dendrimers compounds centred on diarylene photochromic activity nucleus byStille cross-coupling reaction were synthesized. Through the UV absorption spectrometry, We comparedthe influence of the groups on the photochromic properties of the compounds. In chapter six, a conclusion was given.
