S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

open access: yesCarbon Innovation, Volume 1, Issue 1, Page 78-85, June 2026.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.

Metal–Organic Frameworks as Programable Platforms for Micro‐ and Optoelectronics: From Dielectrics to Semiconductors and White‐Light Emitters

open access: yesSmall Science, Volume 6, Issue 6, June 2026.
Programable metal–organic framework (MOF) architectures are revealed as versatile micro‐ and optoelectronic platforms, spanning low/high‐κ dielectrics, semiconductive frameworks, and electrically driven phosphor‐free white emitters. Metal nodes, π‐conjugated linkers, guests, and confined water emerge as decisive handles for tuning charge transport ...
