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

我们设计了新的供体-受体-环烷三元体系，显示出光诱导电子转移等新功能。我们合成了以1,3-二硫醇-2-乙基（DT）为供体单元的正规化DT-环烷，以溴取代物（Br）为弱受体，以芘或HBC为光致电子转移单元的诱导基团。此外，我们还合成了新的含有芘和DT基团的DT-芘-[3.3]副环环烷，以及含有芘和二氰乙基（DCN）基团的DCN-芘-[3.3]副环环烷。我们还通过电子谱、循环伏安图和发射谱获得了正交化dt -芘-[3.3]副环环烯和dcn -芘-[3.3]副环环烯是具有弱分子内电荷转移性质的独特三元体系的良好证据。

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.
