摘要: 以吡咯并四硫富瓦烯衍生物(1)为原料,经过Vilsmeier甲酰化、Wittig反应或交叉偶联反应得到D-π-A二素系化合物(4a, 5a),为了比较以N-甲基吡咯并四硫富瓦烯衍生物(2)出发,用同样的方法合成了N-甲基化的D-π-A二素系化合物(4b, 5b)。用循环伏安法(CV)和UV-VIS研究了目标化合物的电化学和光物理性质,并进行了非线性光学性质的理论计算。

Abstract: The two D-π-A dyad compounds (6a, 7a) were prepared from monopyrrolotetrathiafulvalenes (1) via Vilsmeier formylation and Wittig reaction or cross-coupling reaction . For comparison with 6a and 7a, the N-methylated two D-π-A dyad compounds (6b, 7b) were also obtained from mono-pyrroletetrathiafulvalene(2) using the same process. Their electrochemical and photophysical properties were studied with cyclic voltammetry and UV-VIS spectrum, and theoretical calculation were carried out for their nonlinear optical properties.
