A superbase of t-BuP4 catalysed polyhydroxylation of aromatic diynes was established, and regio-regular poly(vinyl ether)s with versatile properties were produced.

In order to improve the electromagnetic interference (EMI) shielding performance of poly(vinylidene fluoride) (PVDF), both carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) as functional fillers were chosen and employed in this work. The PVDF‐based composites were prepared through melt blending and the hybrid fillers exhibited fine interaction with PVDF matrix. CNTs and GNPs could act as heterogeneous nucleation agents for PVDF matrix, thus increased the crystallization peak temperature. The gradual formation of interconnected conductive network of hybrid fillers could improve the conductivity and rheological properties of PVDF effectively. Especially, in contrast to those of pure PVDF, about four orders of magnitude increment for their storage modulus and complex viscosity of PVDF/GNPs/CNTs composite as well as approximate 10 orders of magnitude improvement in their electrical conductivity were obtained. Adding 2 wt% CNTs in PVDF matrix could generate the conductive network and further GNPs addition was helpful to obtain higher EMI shielding effectiveness. The new PVDF samples would possess wide applications as electromagnetic shielding materials, on account of their simple processing, low‐cost and without use of organic solvent characteristics.

Four novel aggregation-induced emission (AIE)-active luminogens (p-DPDECZ, p-DBPDECZ, m-DPDECZ and m-DBPDECZ) with triphenylethene-carbazole skeleton and para-/meta-substituted arylboron groups have been synthesized.
