• A show of force: Novel polymer that toughens up and changes color upon mechanical stress
  

  A fascinating and crucial ability of biological tissue, such as muscle, is self-healing and self-strengthening in response to damage caused by external forces. Most human-made polymers, on the other hand, break irreversibly under enough mechanical stress, which makes them less useful for certain cri more

• Inverted Fluorescence
  

  Fluorescence usually entails the conversion of light at shorter wavelengths to light at longer wavelengths. Scientists have now discovered a chromophore system that goes the other way around. When excited by visible light, the fluorescent dyes emit light in the ultraviolet region. According to the s more

• Luminous Molecules
  

  Many people know the effect from discos when “black light” makes clothes or writing boards glow. The reason for this are so-called fluorescent dyes. They send back part of the light they are exposed to in a slightly different way and thus glow. Particularly large fluorescent molecules are often inte more

The Chemistry of Turmeric

If you’ve ever made a curry, you’ve likely used turmeric – you may even have some in your kitchen right now. It’s probably not the first thing that comes to mind when you think about doing chemistry, but there are actually some pretty neat chemistry tricks you can do with it! In this post, we take a more

• One-pot synthesis of highly fluorescent Fe2+-doped carbon dots for dual-emissive nanohybrid to detection of zinc ions and histidine

  Metal ions-doping is paid a little attention comparing with the nonmetallic-element doping to improve the fluorescence intensity of carbon dots (CDs). Herein, Fe2+-doped CDs was facilely synthesized at 80 °C instead of hydrothermal method for the first time. Fe2+ was confirmed to be the only definit more

• A benzimidazole-based highly selective colorimetric and far-red fluorometric pH sensor for intracellular imaging

  A turn-on fluorescent probe (E)-4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)-N,N-diphenylaniline (BVD) was facilely synthesized via the ethylene bridging of triphenylamine and benzimidazole. The probe exhibited strong emission enhancement in the vis-NIR fluorescence region at 605 nm with pKa 4.14 and linea more

• Impact of kilobar pressures on ultrafast triazene and thiacyanine photodynamics

  Very short fluorescence lifetimes evidence ultrafast deactivation of photoexcited molecules. To unveil the underlying mechanism for two compounds exhibiting (sub)picosecond emission dynamics, we combine femtosecond fluorescence upconversion with high-pressure liquid-phase spectroscopy. For the triaz more
