Photochromic thieno[3,2-b]thiophenes and dithieno[3,2-b:2′,3′-d]thiophene with photo-switchable luminescence properties have been synthesized using a Suzuki cross-coupling reaction; their electronic structures, and photochromic and luminescence behaviour have also been studied.

larger TPA cross section value. At the same time, they display distinctively different electronic absorption spectra and improved electrochemical amphotericity. Spectroelectrochemical studies revealed a good linear relationship between the optical energy gaps and the molecular length in the neutral, radicalcationic and dicationic forms. Our research work discloses a significant difference between the
由于其独特的光学,电子和磁性性质以及在材料科学中的广阔应用前景,开壳单线态双基自由基最近受到了广泛的关注。在各种双自由基中,醌型π共轭分子已成为普遍的设计。然而,关于融合方式和亲芳香性/反芳香性如何影响其双自由基特性和物理性质的基本理解的需求仍未解决。在这项工作中,合成了一系列的亲芳香族苯并硫杂稠合的[ n ]噻吩并苯并二甲基甲烷(Th n -TIPS(n = 1-3)和BDTh-TIPS),并将其与先前报道的抗芳族双茚并酮[[ n ]硫杂蒽(S n -TIPS,n = 1-4)。通过X射线晶体学分析,可变温度NMR,ESR,SQUID,拉曼光谱和电子吸收光谱,借助DFT计算,系统地研究了这些新的喹啉分子的基态几何和电子结构。发现双基字符指数(y 0)从Th1-TIPS的几乎为零增加到Th2-TIPS的2.4 %,Th3-TIPS的18.2%和BDTh-TIPS的38.2%,由于增强了芳烃

to synthesize linear or semi-circular chelated mononuclear biscarbene and dinuclear tetracarbene complexes. The electronic properties of the annulated thienylene chelated carbenecomplexes were investigated by cyclic voltammetry experiments and compared to non-chelated Fischer-type monocarbene complexes. Density functional theory (DFT) calculations were used to assign the redox events and to probe the
两个(噻吩并[3,2- b ]噻吩)和三个环噻吩(二噻吩并[2,3- b ; 3',2'- d ]噻吩和双噻吩并[3,2- b ; 2',3'- d[噻吩]用作构建基,以合成线性或半圆形的螯合单核双卡宾和双核四卡宾络合物。通过循环伏安法实验研究了环戊二烯螯合卡宾卡宾配合物的电子性质,并将其与非螯合费歇尔型单卡宾配合物进行了比较。密度泛函理论(DFT)计算被用来分配氧化还原事件,并探测电子离域的程度以及由于间隔而引起的电子(分子内金属与金属)通信的可能性。将共轭螯合卡宾络合物中这些电子性质的差异与没有线性共轭途径的螯合卡宾化合物进行了比较。
