通过寡聚（3，4-乙二氧基）噻吩（nEDOT）与1，4，5，8-萘四甲酸二酰亚胺（NDI）的Stille偶联反应，合成了一系列具有高化学稳定性、电化学稳定性、热稳定性和构象稳定性的新型给体-桥-受体配体。分子设计提供HOMO和LUMO轨道的完全分离。硫醇官能团允许通过分子的供体侧或受体侧将二联体选择性锚定到金属电极。通过电化学、光谱电化学和紫外-可见吸收/发射光谱对溶液和金表面自组装膜中的光电性质进行了表征，并通过DFT计算进一步验证了结果。
A series of new donor–bridge–acceptor dyads with high chemical, electrochemical, thermal and conformational stability were synthesized by Stille coupling of oligo(3,4-ethylenedioxy)thiophenes (nEDOTs) and 1,4,5,8-naphthalenetetracarboxydiimide (NDI) building blocks. The molecular design provides for complete separation of HOMO and LUMO orbitals. A thiol functionality allows for selective anchoring of the dyads to metal electrodes, through either the donor or acceptor sides of the molecule. The optoelectronic properties of the dyads, both in solution and in self-assembled monolayers on gold, were characterized by electrochemistry, spectroelectrochemistry and UV-Vis absorption/emission spectroscopy and the results were further supported by DFT calculations.
