Advanced Materials Interfaces, EarlyView.An electrolyte‐gated field effect transistor sensor is used to detect an environmentally relevant nanoplastic model. The sensor identifies the presence of polystyrene nanoplastics in water dispersions without significantly altering its performance in the presence of mercury on the nanoplastics’ surface, indicating that it may be utilized in ...

Advanced Optical Materials, EarlyView.A new class of diarylethene compounds containing backbone phosphine oxide groups are reported, exhibiting turn‐on aggregation‐induced emission. Side chain functionalization enabled emission color tunability and turn‐on anti‐Kasha emission. Abstract Diarylethenes (DAE) are a well‐known class of photochromic compounds with diverse applications ranging ...

Advanced Optical Materials, EarlyView.By combining static and time‐resolved optical, structural, and rheological techniques, we demonstrate that the blue‐shift upon solidification of ethyl cellulose‐acrylic acid mesophases corresponds to the reorientation of cholesteric domains. Modulating the mesophase chain mobility and photopolymerization reaction kinetics enables solid chiral nematic ...
