SuBiCH - one step synthesis for Substituted Bisimide dyes via CH-activation

24.09.2013
Perylene dyes are common industrial substances, which are used not only as printer or textile dyes, but also as active compounds in organic electronic devices such as LEDs or solar panels. Furthermore, the physiological effect of some derivatives is known, e.g. as telomerase inhibitors.

The conventional multi-step synthesis of amine perylene derivates via bromo or nitro derivates is complex and expensive, since either a large excess of bromine is necessary or expensive alkyl bromides must be used. Scientists of the University of Bonn invented a new method to overcome this problem. SuBiCH describes the one-step preparation of amino-substituted perylene derivatives (such as bis-imides) under mild conditions.

Im Focus: Elucidating the Atomic Mechanism of Superlubricity

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.

One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
