Abstract:

Five different poly(arylene-diarylvinylene)s have been synthesized by reductive polyolefination starting from the corresponding bis(?,?-dichlorobenzyl)-substituted monomers and dicobaltoctacarbonyl as reducing agent. The resulting polymers all contain main chain tetraphenylethylene units. Thanks to the aggregation-induced emission effect, the corresponding polymer films show remarkably high photoluminescence quantum yields (PLQYs) of 32%-73%. The polymer with the highest PLQY is tested as solid state sensing material for the PL-quenching-based detection of nitroaromatic analytes (1,3,5-trinitrobenzene as prototypical analyte). © 2016 WILEY-VCH Verlag GmbH & Co.
