π‐Expanded Fluoranthenes as Chromophores With Tailored Properties
Helvetica Chimica Acta, EarlyView.A series of π‐expanded fluoranthene scaffolds selectively functionalized with electron donors and acceptors were synthesized. The evolution of the structural, optoelectronic, and redox properties in relation to substitution and cyclization was comprehensively studied both in experiment and in theory. The results identify the compounds as highly tunable

Reversible Nanocomposites With Carbon Nanotubes as the Diene in the Diels–Alder Reaction
Polymer Composites, EarlyView.Scheme of the reversible nanocomposites through DA and rDA reactions with participation of carbon nanotubes. ABSTRACT Carbon nanotubes (CNTs) often require surface functionalization to facilitate uniform distribution and address issues related to aggregation. Due to the sp2 hybridized carbon atoms on their surface, CNTs readily participate in the Diels–

Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin
Smart Molecules, EarlyView.The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.
