electron-withdrawing (A) unit is thiazole group. Furthermore, in this report, we present the complexation studies of both the BTA and 2-TPA-BTA chromophores with Cu(II) and Pd(II), respectively. The crystal structures are established by single-crystal X-ray diffraction analysis. These studies not only provide the general photophysical principles of the materials based on BTA moiety but also encourage progress toward
通过镍(0)介导的山本型偶联制备聚(5,5'-(2-己基癸基)-双噻唑-2-基-胺)(PBTA)。THF溶液中PBTA的光致发光(PL)光谱显示纯蓝色发射,峰值位于444 nm,没有任何肩峰,PBTA的HOMO和LUMO值分别估计为5.11和2.90 eV。此外,我们合成了一种新型的以双噻唑-2-基胺(BTA)为核心的供体-受体(DA)生色团体系,即5-(4-(二苯基氨基)苯基)-N-(5-(4 -(二苯基氨基)苯基)噻唑-2-基)-N-辛基噻唑-2-胺(2 - TPA - BTA),其中供电子(D)部分是三苯胺基,吸电子(A)单元是噻唑基。此外,在本报告中,我们介绍了BTA和2 - TPA - BTA发色团分别与Cu(II)和Pd(II)的络合研究。通过单晶X射线衍射分析确定晶体结构。这些研究不仅提供了基于BTA部分的材料的一般光物理原理,而且还鼓励在实现其杂化金属-有机骨架的全部潜力方面取得进展。
