中文摘要：

设计合成了4种对称的以不同供/吸电子基团为共轭桥、两端连接meso位苯或噻吩取代的新型氟化硼二吡咯甲川（BODIPY）衍生物;通过1H NMR,13C NMR和MS等手段对其进行了结构表征;并采用紫外吸收光谱、荧光发射光谱及循环伏安（CV）等方法研究了其光电性能.紫外光谱数据表明,BODIPY结构具有明显的特征吸收,中间的桥联基团无论是强供电子的苯并二噻吩（BDT）还是强吸电子的苯并噻二唑（BT）均不能使整个分子产生明显的分子内电子迁移（ICT）.另一方面,meso位的取代基可与BODIPY核产生微弱的ICT,且meso位噻吩取代的分子比meso位苯环取代的分子表现出更强的ICT.紫外光谱数据和电化学测试结果表明,meso位噻吩取代的分子比meso位苯环取代的分子具有更低的氧化电位和更窄的能隙.

英文摘要：

Four novel symmetrical 4,4＇-difluoro4-bora-3a, 4a-diaza-sindacene （BODIPY） derivatives were synthesized. These BODIPY derivatives bear different donor or acceptor units as conjugate bridge, and the BODIPYs meso-position substituted by thiophene or benzene as the termini groups. The structures of all the compounds were identified by l H NMR, 13C NMR and MS techniques. The photopbysical properties of these compounds were measured by the UV-Vis absorption and the fluorescence emission spectrophotometer. And the electrochemical properties were investigated by the cyclic voltammetry. The results of absorption spectra confirmed that these BODIPYs had a characteristic absorption peak, and the conjugate bridges had little influence on the intramolecular charge-transfer（ICT） interaction neither used as donor nor acceptor. On the other hand, meso-position substituentes have a weak influence on the ICT interaction in the BODIPYs, and meso-position thiophene substituted ones have raised more intensive ICT than the meso-position benzene substituted ones. Both the absorption spectra and cyclic voltammetry data indicate that BODIPYs with raeso- thiophene substitutuents possess a lower oxidation potential and a narrower band gap than those meso-position benzene ones.
