Covalently bonded single-molecule junctions with stable and reversible photoswitched conductivity
A fully reversible, two-mode, single-molecule electrical switch with unprecedented levels of accuracy, stability, consistency, and reproducibility is demonstrated.
Influence of the donor size in D-π-A organic dyes for dye-sensitized solar cells.
We report two new molecularly engineered push-pull dyes, i.e., YA421 and YA422, based on substituted quinoxaline as a π-conjugating linker and bulky-indoline moiety as donor and compared with…
New Diketopyrrolopyrrole (DPP) Dyes for Efficient Dye-Sensitized Solar Cells
Two novel metal-free dyes (DPP-I and DPP-II) with a diketopyrrolopyrrole (DPP) core were synthesized for dye-sensitized solar cells (DSSCs). The absorption spectra and electrochemical and…

The tumor-targeting ability and the specific drug release in tumors make DCM-S-CPT as a promising prodrug, providing significant advances toward deeper understanding and exploration of theranostic drug-delivery systems.
Organic D‐A‐π‐A Solar Cell Sensitizers with Improved Stability and Spectral Response
A novel concept “D‐A‐π‐A” organic sensitizer instead of traditional D‐π‐A ones is proposed. Remarkably, the incorporated low bandgap, strong electron‐withdrawing unit of benzothiadiazole shows…
Diketopyrrolopyrrole (DPP)-based materials for organic photovoltaics.
The application of DPP-based materials is described, highlighting the applications in optoelectrical fields.
Förster resonance energy transfer (FRET)-based small-molecule sensors and imaging agents.
The underlying energy donor-acceptor dye combinations and their applications for the detection or imaging of cations, anions, small neutral molecules, biomacromolecules, cellular microenvionments and dual/multi-analyte responsive systems are discussed.

It is shown that a wild-type aerolysin nanopore can resolve individual short oligonucleotides that are 2 to 10 bases long and can monitor the stepwise cleavage of oligon nucleotides by exonuclease I.
Triarylamine: A Promising Core Unit for Efficient Photovoltaic Materials
Single-molecule DNA detection using a novel SP1 protein nanopore.
SP1 protein as a new type of biological nanopore is described and is utilized to distinguish single-stranded DNA at the single-molecule level, which could provide a good candidate for single-Molecule detection and characterization of biomaterial applications.
