Strengthened Interfacial Coupling Between Self‐Assembled Monolayers and Bulk Heterojunctions Enables Thermally Stable Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

Biomass Photochemistry Ix:photochemical Pretreatment Of Cellulose And Its Effect On Cellulase Efficiency

open access: yes, 2015
Cellulose derivatives were irradiated by UV light at λ > 254 nm and λ > 300 nm. The degradation of cellulose derivatives was followed by fluorescence, viscosimetry, weight loss and thermogravimetry measurements.

Surface‐Ligand‐Dependent Excited‐State Dynamics in Aqueous CuInSe2/ZnS Quantum Dot–Chlorophyll Assemblies

open access: yesAdvanced Materials Interfaces, EarlyView.
CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...
