Synthesis and characterization of poly(3-hexylthiophene)-functionalized siloxane nanoparticles

Abstract

Poly(3-hexylthiophene)-functionalized siloxane nanoparticles were prepared by a modified Stöber method. The photovoltaic performance of P3HT-nanohybrids with C60 derivative PCBM was evaluated. The device made from 1 : 1 blends of P3HT-NPs:PCBM showed reasonably good photovoltaic performance with a power conversion efficiency of 2.5% under standard test conditions (AM 1.5G, 100 mW cm(-2)).

Preparation of n-type semiconducting polymer nanoarrays by covalent synthesis followed by crystallization

“…The polymerization was induced by the addition of the alcohol-base solution resulting an aggregated light red suspension in the upper layer and a translucent red colored bottom layer in a few minutes. 24,25 The base catalyzed condensation usually has less condensing ability compared to acid catalyzed hydrolysis on silanols with electron donating groups.

“…13 N-type materials are more demanding in creating ordered networks with p-type semiconductors for electronic device applications especially for OPVs. 24,25 Nonetheless, reports to date on preparing ordered nanostructures from semiconducting polymers are very limited. [19][20][21][22] The self-assembled 1D-structures of PDIs such as nanowires, 5,22,23 nanobelts, 8,9 nanotubes, 10,11 and nanofibres 12 were introduced through a variety of techniques such as phase transfer, solvent annealing, vapour diffusion, and seeded growth.…”

A sol–gel synthesis to prepare size and shape-controlled mesoporous nanostructures of binary (II–VI) metal oxides

“…Since the introduction of Stöber silica particles from base catalyzed hydrolysis and condensation of tetraethyl orthosilicate by Stöber et al, 1 the solgel method has been signicantly advanced and implemented to make solid materials, such as inorganic oxides, organicinorganic hybrids, and organosilica, with excellent electrical, optical, magnetic, thermal, and mechanical properties. [2][3][4] The precursor to base concentration, solvent polarity, low temperature, additives type, and nucleation growth are few important factors that add merit to obtain morphology-controlled nanomaterials with high surface to volume ratio. As shape, size, and packing structure of the nanostructures play a crucial role for building next-generation devices and therapeutic materials, the sol-gel method is an excellent tool to fabricate metal oxide nanostructures, with size-dependent superior properties, particularly for optics and electronics.…”

“…Herein, PMR‐SSQ nanoparticles were prepared, utilizing a previous method developed by our group . Our group has introduced a modified Stöber sol–gel route to make organic semiconductors‐functionalized SSQ nanostructures, having potential applicability in organic‐based photovoltaic devices . The method developed to make these dye‐functionalized SSQ nanoparticles has shown to be very useful in incorporating a higher load of organic functionality into the SSQ network to obtain highly functionalized dimensional architectures.…”
