Two conjugated polymers (CPs) with various compositions of phenylene and benzoselenadiazoben (BSD) are synthesized to have a special emitting property; different fluorescence colors in solution and in the solid states, allowing the resulting conjugated polymer dots (Pdots) to emit different fluorescence colors upon their size variation. The photophysical property of such different‐sized Pdots is investigated...
As conjugated polymer nanoparticles (CPNs) have attracted growing interest as photoacoustic (PA) imaging contrast agents, revelation of the relationship between the molecular structure of conjugated polymers and PA property is highly in demand. Here, three donor–acceptor‐structured conjugated polymer analogs are designed, where only a single heteroatom of acceptor units changes from oxygen to sulfur...
Carbon nanomaterials exhibit extraordinary mechanical and electronic properties desirable for future technologies. Beyond the popular sp2‐scaffolds, there is growing interest in their graphdiyne‐related counterparts incorporating both sp2 and sp bonding in a regular scheme. Herein, we introduce carbonitrile‐functionalized graphdiyne nanowires, as a novel conjugated, one‐dimensional (1D) carbon nanomaterial...
Creating a new gadget to conventional analytical methods on π‐conjugated materials is meaningful in improving quantitative recognition technologies. In article number 1800512, Dong June Ahn and co‐workers explore quantified monitoring by means of narrow‐band resonance Raman scattering that analyzes phase‐shifting characteristics of π‐conjugated polydiacetylene probes responding to various perturbation...
The present study reports a quantified monitoring by means of in situ resonance Raman scattering that analyzes phase‐shifting characteristics of π‐systems upon interacting with target analytes. A chemo‐ and thermochromic polydiacetylene vesicular probe is evaluated with multiple‐wavelength Raman scattering modes in resonance with its phases, respectively, and thus can trace the phase‐shifts. This...
Three dibenzothiophene‐S,S‐dioxide‐based alternating copolymers were synthesized by facile Suzuki polymerization for visible light–responsive hydrogen production from water (> 420 nm). Without addition of any cocatalyst, FluPh2‐SO showed a photocatalytic efficiency of 3.48 mmol h−1 g−1, while a larger hydrogen evolution rate (HER) of 4.74 mmol h−1 g−1 was achieved for Py‐SO, which was ascribed...
Responsive materials, which can adapt and operate autonomously under dynamic conditions, are a stepping stone towards functional, life‐like systems inspired by fueled self‐assembly processes in nature. Complex coacervate core micelles (C3Ms) comprising oppositely charged macromolecules constitute a novel class of polymeric micelles ideally suited for use as responsive nanoscopic delivery vehicles...
In article number 1802089, Ilja K. Voets and co‐workers report on the temporally programmed, self‐regulating formation and dissociation of complex coacervate core micelles (C3Ms) comprising a double hydrophilic block copolymer and a pH‐responsive polyfluorene‐based conjugated polyelectrolyte as building blocks and a molecular sensor (doxorubicin HCl) as cargo. The latter (macro)molecular probes report...
