• Electric cars: Special dyes could prevent unnecessary motor replacements
  

  One day in the near future dyes in electric motors might indicate when cable insulation is becoming brittle and the motor needs replacing. Scientists at Martin Luther University Halle-Wittenberg (MLU), together with ELANTAS, a division of the specialty chemicals group ALTANA, have developed a new pr 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

• A question of affinity
  

  A collaboration of scientists from the Max Planck Institute for Polymer Research (MPI-P) in Germany and the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have recently scrutinized organic solar cells and derived design rules for light-absorbing dyes that can help to make more

The Chemistry of Highlighter Colours

If you’re currently a student, then you’ll no doubt often make ample use of highlighters during revision. Even if your studying days are far behind, you probably still use them from time to time. But what are the chemicals behind their luminous colours? This graphic looks at some of the possible dye more

The Chemistry of Glow Sticks

Everyone’s familiar with glow sticks, but it’s likely that fewer are familiar with the chemistry behind their glow. You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of t more

The Key Chemicals in Red Wine

Red wine has been espoused over the years for its supposed health benefits, from claims that it could let us live to 150, to assertions that chemicals within it can help prevent cancer. Whilst these are no doubt a very pleasant means to justify a glass of wine (or several), how correct are they? Sim more

• A simple and versatile strategy for realizing bright multicolor mechanoluminescence

  Multicolor mechanoluminescence(ML) is first realized by using the stable organic blue ML emitter N-henylcarbazole as host matrix. It is claimed that a good ML host should have a moderate melting point and can dissolve or disperse organic dyes but maintain high ML activity and crystallinity. This str more

• A bifunctional cationic metal–organic framework based on unprecedented nonanuclear copper(II) cluster for high dichromate and chromate trapping and highly efficient photocataly ...

  A bifunctional cationic metal–organic framework {[Cu9(OH)6Cl2(itp)6(1,4-bdc)3](NO3)2(OH)2·20H2O}n (1-NO3-OH·20H2O) was synthesized and characterized (itp = 1-imidazol-1-yl-3-(1,2,4-triazol-4-yl)propane, 1,4-bdc = 1,4-benzenedicarboxylate).
