In this work, we compare two structurally near-amorphous rigid-rod polymers─poly(indacenodithiophene-
Indacenodithiophene (IDT) copolymers are a class of conjugated polymers that have limited long-range order and high hole mobilities, which makes them promising candidates for use in deformable electronic devices. Key to their mobilities is the coplanar monomer repeat units within backbone. Poly(indacenodithiophene-benzothiadiazole) (PIDTC16-BT) poly(indacenodithiophene-thiapyrollodione) (PIDTC16-TPDC1) two IDT with planar backbones, but they brittle at low molecular weight unsuitably elastic...
Poly(indacenodithiophene-benzothiadiazole) has received significant interest because of its exceptional hole mobility despite near-amorphous thin-film morphology and brittleness at low Mn. In comparison, poly(indacenodithiophene-benzopyrollodione) (PIDTBPD) a lower but is exceptionally ductile similar Herein, we synthesize random indacenodithiophene (IDT) copolymers with varying amounts incorporated benzothiadiazole benzopyrollodione (BPD), which introduces varied degrees backbone twist to...

Abstract A comparative study involving bimetallic nickel catalysts designed from disubstituted N,N,N′,N′ ‐tetra(diphenylphosphanylmethyl)benzene diamine bridging ligands is reported. Catalyst behavior explored in the Kumada catalyst‐transfer polymerization (KCTP) using poly(3‐hexylthiophene) (P3HT) as model system. The success of a controlled monitored by analyzing monomer conversion, degree polymerization, end‐group identity, and molecular weight distribution. characterization P3HT obtained...
A strained, cyclic hydrocarbon comprising a meta ‐quaterphenyl‐based arc that is clamped by an alkyne tether was synthesized via Yamamoto coupling of dichloro precursor. DFT calculations (B3LYP/6‐31G*) indicate the lowest‐energy ground state adopts twisted, C 2 conformation bears 19.0 kcal/mol strain energy. X‐ray crystallographic analysis confirms that, in solid state, molecule twisted structure similar to calculated conformation. Exposure ortho ‐linked precursor conditions generates...
The Cover Feature shows a young archer carefully aiming his bow at target in the background. synthetic shown foreground incorporates short alkyne linker that clamps meta-quaterphenyl group, generating strain much like taut string creates tension an archer's bow. To illustrate this effect, cartoon threads through exterior benzene rings of quaterphenyl unit and tightens knot, drawing benzenes closer together. Photograph courtesy Alan Richard.
