Synthesis of Three-Dimensionally Synthesis of Three-Dimensionally Molecular Photodiode Devices with Electron Transfer Control Function

我们设计了新的给体-受体-环蕃三元体系，该体系具有光诱导电子转移等新功能。 我们合成了以1，3-二巯基-2-亚基（DT）为给体单元，溴取代基（Br）为弱受体，以芘或HBC为光诱导电子转移单元的正交化DT-环番。 此外，我们还合成了新的含芘和DT结构的DT-芘- [3.3]对环芳和含芘和二氰基乙叉（DCN）结构的DCN-芘-[3.3]对环芳。 通过电子光谱、循环伏安图和发射光谱的研究，我们也得到了很好的证据，证明了正交化的DT-芘-[3.3]对环芳和DCN-芘-[3.3]对环芳是具有弱分子内电荷转移性质的三元体系的独特例子。

We designed new donor-acceptor-cyclophane triad systems that show new functions such as photoinduced electron transfer. We synthesized orthogonalized DT-cyclophanes linked with a 1,3-dithiol-2-ylidene (DT) moiety as a donor unit and bromine substitutes (Br) as a weak acceptor and induced group to pyrene or HBC as photoinduced electron transfer unit. Furthermore, we synthesized new DT-pyrene- [3.3]paracyclophanes with pyrene and DT moieties, and DCN-pyrene-[3.3]paracyclophanes with pyrene and dicyanoethylidene(DCN) moieties. We also obtained good evidence that orthogonalized DT-pyrene-[3.3]paracyclophanes DCN-pyrene-[3.3]paracyclophanes and are the unique examples of triad systems with weak intramolecular charge transfer properties by electronic spectra, cyclic voltammograms, and emission spectra.
