Advanced Science, EarlyView.Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...

Advanced Science, EarlyView.We report, for the first time, an external electric field (EEF) strategy to achieve co‐aggregation of conjugated polymer blends (i.e., poly(3‐butylthiophene) and poly[3,3'''‐dialkyl‐quaterthiophene]s) in the solution and thus their cocrystals in thin films, demonstrating cocrystal‐improved charge mobilities due to the synergy of two components ...

Copolymerization parameters [PDF]
Journal of Polymer Science, 1961 AbstractCopolymerization parameters, Q and e, have been calculated for several monomers whose relative reactivity ratios, r1 and r2, are available. The ratios and parameters are tabulated in an effort to bring the various data in the literature to a single source of reference.

Nickel‐Catalyzed Twofold Conjunctive Coupling via Philicity‐Alternating Radical Relay
Advanced Science, EarlyView.Herein, we disclose a nickel‐catalyzed twofold conjunctive coupling that enables a four‐component assembly involving an activated alkene, a 1,3‐enyne, and both alkyl and aryl halides. Multiple C–C bonds are selectively constructed through a philicity‐alternating radical relay and the selective radical capture by the nickel catalyst.

Expanding the Chemical Space of Cyclic Polyphthalaldehyde via Post‐Functionalization
Advanced Science, EarlyView.In this work, we developed a post‐functionalization approach to achieve water‐soluble cyclic polyphthalaldehyde (cPPA) polymers via click chemistry. ABSTRACT Cyclic polyphthalaldehydes (cPPAs) are hydrophobic cyclic polymers with stimuli‐responsive depolymerization property. The introduction of hydrophilic functionalities to cPPAs is challenging due to
