A simple one-pot synthetic strategy toward crafting semiconductor organic–inorganic nanocomposites composed of conjugated polymer poly(3-hexylthiphene) (P3HT) in close contact with CdE (E=S, Se, and Te) nanocrystals was introduced. Bifunctional ligand 4-azidobenzoic acid (BA-N₃) that possesses two end functionalities at each end was employed, enabling the coordination of BA-N₃ with Cd first to yield Cd-carboxylic acid complexes (Cd-BA-N₃) followed by the subsequent click reaction between Cd-BA-N₃ and ethynyl-terminated P3HT (P3HT–≡) to produce P3HT-grafted Cd complexes (Cd-BA-P3HT). Finally, injection of precursors resulted in P3HT-tethered CdE NC (E=S, Se, and Te) nanocomposites. The success of click reaction was confirmed by the Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy measurements. The photophysical properties such as charge transfer characteristics were corroborated with absorbance and photoluminescence characterization. Notably, this strategy circumvents the use of insulating fatty ligands, thus dispensing the need for tedious ligand exchange procedure.

介绍了一种简单的一锅合成策略，用于制备由与CdE（E = S，Se和Te）纳米晶体紧密接触的共轭聚合物聚（3-己基噻吩）（P3HT）组成的半导体有机-无机纳米复合材料。使用在每个末端具有两个末端官能团的双功能配体4-叠氮苯甲酸（BA-N ₃），使BA-N ₃首先与Cd配位，然后生成Cd-羧酸配合物（Cd-BA-N ₃） Cd-BA-N ₃之间的随后点击反应和乙炔基封端的P3HT（P3HT–≡）生成P3HT接枝的Cd络合物（Cd-BA-P3HT）。最后，前驱物的注入产生了P3HT系留的CdE NC（E = S，Se和Te）纳米复合材料。点击反应的成功通过傅里叶变换红外光谱和核磁共振光谱测量得到证实。光物理性质（如电荷转移特性）与吸光度和光致发光特性得到证实。值得注意的是，该策略绕开了绝缘的脂肪配体的使用，从而免除了繁琐的配体交换程序的需要。
