Nanoporous and nonporous conjugated donor–acceptor polymer semiconductors for photocatalytic hydrogen production
Beilstein J. Nanotechnol. 2021, 12, 607–623, doi:10.3762/bjnano.12.50
- ), as a vital experimental parameter for photocatalytic performance, exceeded 9% at 420 nm, which is, to date, the highest among all reported conjugated polymer-based photocatalysts. In addition, phenanthroline–pyrene-based D–A polymers were studied [63], with polymer P34 (phenanthroline/pyrene = 1/3
- The benzothiadiazole (BT) moiety as a strong electron acceptor features high planarity and good wettability due to incorporating N and S atoms. In 2016, Wang and co-workers [65] investigated the properties of a linear conjugated polymer and a 3D counterpart by varying the substitution position on the
Rational design of block copolymer self-assemblies in photodynamic therapy
Beilstein J. Nanotechnol. 2020, 11, 180–212, doi:10.3762/bjnano.11.15
- ]. Among them self-quenching and Förster resonance energy transfer (FRET) quenching are the most frequently used in self-assembled nanocarriers. An alternative possibility to avoid quenching is to mix the photosensitizer-conjugated polymer with a polymer without photosensitizers [82]. Interestingly, the
Widening of the electroactivity potential range by composite formation – capacitive properties of TiO2/BiVO4/PEDOT:PSS electrodes in contact with an aqueous electrolyte
Beilstein J. Nanotechnol. 2019, 10, 483–493, doi:10.3762/bjnano.10.49
- vanadate using pulsed laser deposition. The formation of the TiO2/BiVO4 junction leads to enhancement of pseudocapacitance in the cathodic potential range. The third component, the conjugated polymer PEDOT:PSS, was electrodeposited from an electrolyte containing the monomer EDOT and NaPSS as a source of
- π-conjugated polymer chains [70]. TiO2 in a form of nanotubes have been already tested as electrodes for supercapacitor working in a contact with an aqueous electrolyte. Pristine nanotubes exhibited capacitance equal to about 0.9 mF·cm−2 [71]. Commonly used hydrogenation procedure leads to the
Cytotoxicity of doxorubicin-conjugated poly[N-(2-hydroxypropyl)methacrylamide]-modified γ-Fe2O3 nanoparticles towards human tumor cells
Beilstein J. Nanotechnol. 2018, 9, 2533–2545, doi:10.3762/bjnano.9.236
- studies of Dox-conjugated polymer-coated γ-Fe2O3 nanoparticles by primary cells (hMSCs) and human tumor cells (MG-63 and HeLa) were carried out as follows. The cells were incubated with appropriate amounts of the particle colloids for 48 h and washed with PBS three times to remove dissolved compounds not
Electrospun one-dimensional nanostructures: a new horizon for gas sensing materials

Electro-optical interfacial effects on a graphene/π-conjugated organic semiconductor hybrid system
Beilstein J. Nanotechnol. 2018, 9, 963–974, doi:10.3762/bjnano.9.90
- exactly the case for the amorphous multilayered RA sample. However, in the RA monolayer case, the phenomenology is different. As previous works have demonstrated, structural organization in π-conjugated polymer films can improve their electrical [3][31][32] and optical [30][32][33] properties. The
Spin-chemistry concepts for spintronics scientists
Beilstein J. Nanotechnol. 2017, 8, 1427–1445, doi:10.3762/bjnano.8.143
- bipolarons, electron–hole (polaron) pairs (or charge transfer excitons), but also polarons interacting with triplets, as well as triplet–exciton pairs. The bipolaron model [83] can explain a positive magnetoresistance in energetically disordered systems, such as a conjugated polymer film. A mobile polaron is
Vapor deposition routes to conformal polymer thin films

- that can be used as a cathode for micro lithium ion batteries. Composite electrodes for supercapacitors have been developed by forming pseudo-capacitive, conjugated polymer thin films on various electrodes such as vertically aligned CNTs, aligned graphene flakes, and nano-porous anodized alumina (NAA

- exceed the exciton diffusion length [12], which is the case for ECP–fullerene-based solar cells in which fullerene molecules are able to capture the negative charges while the holes remain on the conjugated polymer [13]. Still, evidence for similar photoinduced charge-transfer or energy-transfer
Caveolin-1 and CDC42 mediated endocytosis of silica-coated iron oxide nanoparticles in HeLa cells
