Abstract:A novel nanocomposite of P3HT and Ag nanoparticles (Ag-P3HT) has been synthesized by laser ablation. The fluorescence wavelength of the nanocomposite can be tuned by varying the ablation duration. The steady-state emission maximum at 580 nm for pristine P3HT shows significant blueshift to wavelengths ranging from 520 to 550 nm for Ag-P3HT. NMR, FTIR and XPS spectroscopy confirm that chemical links are formed between P3HT and silver nanoparticles (NPs) in the nanocomposite. For the sample with an emission maximum at 530 nm, 1 H NMR spectra indicate that 66% of the P3HT thiophene ring protons are replaced by Ag NPs. Time-resolved spectroscopy demonstrates that charge transfer efficiency increases for Ag-P3HT and this is attributed to the enhanced intimate interfacial contact between the chemically-bonded metal NPs and polymer chains. The synthetic route outlined provides a one-pot and green strategy for producing metal-organic polymeric materials, with controlled luminescence wavelengths and efficient photoinduced charge transfer that meet the requirement for developing high-performance organic light-emitting and photovoltaic devices.

“…Grafting P3HT with CdSe by a chemical method is an effect strategy to eliminate phase separation and to promote the electronic interaction between P3HT and CdSe [6,8]. Previously, the ligand exchange process was used to graft CPs to NCs because the derivatization of the composite has a broad range of functional groups [9,10]. In spite of the fact that the original ligands can be replaced by the desired ligands, NCs still tend to aggregate when mixed with CPs, which leads to phase separation [11][12][13][14].…”

“…Many works on the synthesis of CP/NC nanocomposites have been reported [9,19,[24][25][26][27][28][29][30][31]. But some key chemicals, such as tri-n-octylphosphine oxide (TOPO) and trioctylphosphine (TOP), used in traditional routes are extremely toxic, expensive, explosive, and pyrophoric [7,11,12,28,31].…”

“…CdSe NCs obtained from the phosphine-free solvent systems are generally imperfect. The size of CdSe NCs is not easily controlled [9,32,35], and their surface is not suitable for epitaxial growth [36,37]. An environmentally friendly, effective, and ligand exchange-free method should be developed to achieve chemically grafted CPs on the QD surface.…”

Carboxyl end-functionalized poly(3-hexylthiophene) (P3HT-COOH) was grafted chemically with CdSe nanocrystals (NCs) by a phosphine-free method. The particle quality of P3HT-COOH/CdSe nanocomposites was better than that of P3HT/CdSe nanocomposites, which were synthesized using the same method. Nanocrystals with controllable particle size exhibited a wurtzite crystalline structure and showed excellent nanocrystal dispersion in the P3HT-COOH matrix. Photoluminescence (PL) characterization performed on nanocomposites suggested the efficient charge transfer at the P3HT-COOH/CdSe interface. This approach based on the phosphine-free method is not only environmentally friendly but also highly efficient.

“…For these reasons, the HOISC's properties depend strongly on the inorganic nanostructures, due to the carriers' interchange, geometry, composition and the absorption edge of the nanostructures used [2]. There are a lot of potential inorganic compounds suitable for HOISC, but metal oxides and chalcogenides are the most studied because of their appropriate optical properties [4][5][6][7][8][9][10][11].…”
