Here, we synthesized and characterized a novel two-dimensional (2D) conjugated electron donor-acceptor (D-A) copolymer (PBDB-T-Ge), wherein the substituent of triethyl germanium was added to the electron donor unit of the polymer. The Turbo-Grignard reaction was used to implement the group IV element into the polymer, resulting in a yield of 86%. This corresponding polymer, PBDB-T-Ge, exhibited a down-shift in the highest occupied molecular orbital (HOMO) level to -5.45 eV while the lowest unoccupied molecular orbital (LUMO) level was -3.64 eV. The peaks in UV-Vis absorption and the PL emission of PBDB-T-Ge were observed at 484 nm and 615 nm, respectively.
在此，我们合成并表征了一种新型二维（2D）共轭电子供体-受体（D-A）共聚物（PBDB-T-Ge），其中三乙基锗取代基被添加到聚合物的电子供体单元中。采用Turbo-格氏反应将第IV族元素引入聚合物中，产率为86%。这种相应的聚合物PBDB-T-Ge的最高占据分子轨道（HOMO）能级下移至-5.45 eV，而最低未占据分子轨道（LUMO）能级为-3.64 eV。PBDB-T-Ge的紫外-可见吸收峰和光致发光发射峰分别在484 nm和615 nm处被观察到。
