Enlightening and flexing memories

by Professor Stefan Hecht, who is a member of IRIS Adlershof, in collaboration with the University of Strasbourg & CNRS (France) and the University of Nova Gorica (Slovenia), have shown that a carefully chosen blend of a small photoswitchable molecule and a semiconducting polymer can be used to fabricate high-performance memory devices that can be written and erased by light. Such multilevel (8...

Microwave-accelerated synthesis of lengthy and defect-free poly(m-phenyleneethynylene)s via AB' and A2 + BB' polycondensation routes.

Genome-wide strategies identify molecular niches regulated by connective tissue-associated transcription factors

Photoswitchable triple hydrogen-bonding motif.

Photochromic bis(thiazol-4-yl)maleimides, displaying enhanced binding affinity to complementary melamine receptors in their ring-closed switching state, have been developed and could pave the way to light-responsive supramolecular assemblies.

Practical synthesis of an amphiphilic, non-ionic poly(para-phenyleneethynylene) derivative with a remarkable quantum yield in water.

Aggregation of poly(para-phenyleneethynylene)s is efficiently suppressed by introduction of branched oligoethyleneglycol side chains rendering the polymer backbone, which is readily obtained using an A2 + BB' polycondensation protocol, soluble and highly emissive in aqueous environments.
