Title: Hybrid Block Copolymer Synthesis by Merging Photoiniferter and Organocatalytic Ring‐Opening Polymerizations
Abstract Access to block copolymers from monomers that do not polymerize via a common mechanism requires initiation from a multifunctional species that allows orthogonal polymerization chemistries. We disclose a strategy to provide well‐defined polyacrylamido‐b‐polyether block copolymers by a one‐pot combination of photoiniferter polymerization and organocatalytic ring‐opening polymerization (ROP) using a hydroxy‐functionalized trithiocarbonate photoiniferter as the dual initiator at ambient temperature. Our results reveal good compatibility between the two polymerization systems and highlight that they can be performed in arbitrary order or simultaneously with good retention of the thiocarbonylthio functionality. We also demonstrate selective temporal control over the photoiniferter polymerization during concurrent ROP. We harnessed the efficiency of combining these polymerization systems to provide tailor‐made block copolymers from chemically distinct monomers.  more » « less

    Abstract This work develops the Polyolefin Active‐Ester Exchange (PACE) process to afford well‐defined polyolefin–polyvinyl block copolymers. α‐Diimine PdII‐catalyzed olefin polymerizations were investigated through in‐depth kinetic studies in comparison to an analog to establish the critical design that facilitates catalyst activation. Simple transformations lead to a diversity of functional groups forming polyolefin macroinitiators or macro‐mediators for various subsequent controlled polymerization techniques. Preparation of block copolymers with different architectures, molecular weights, and compositions was demonstrated with ring‐opening polymerization (ROP), nitroxide‐mediated polymerization (NMP), and photoiniferter reversible addition–fragmentation chain transfer (PI‐RAFT). The significant difference in the properties of polyolefin–polyacrylamide block copolymers was harnessed to carry out polymerization‐induced self‐assembly (PISA) and study the nanostructure behaviors.

    Abstract Ring‐opening polymerization (ROP) of lactones or cyclic (di)esters is a powerful method to produce well‐defined, high‐molecular‐weight (bio)degradable aliphatic polyesters. While the ROP of lactones of various ring sizes has been extensively studied, the ROP of the simplest eight‐membered lactone, 7‐heptanolactone (7‐HL), has not been reported using metal‐based catalysts. Accordingly, this contribution reports the ROP of 7‐HL via metal‐catalyzed coordinative‐insertion polymerization to the corresponding high‐molecular‐weight polyester, poly(7‐hydroxyheptanoate) (P7HHp). The resulting P7HHp is a semi‐crystalline material, with aTmof 68 °C, which is ~10 °C higher than poly(ε‐caprolactone) derived from the seven‐membered lactone. Mechanical testing showed that P7HHp is a hard and tough plastic, with elongation at break >670%. P7HHp‐based polyesters with higherTmvalues have been achieved through stereoselective copolymerization of 7‐HL with an eight‐membered cyclic diester, racemic dimethyl diolide (rac‐8DLMe), known to lead to highTmpoly(3‐hydroxyburtyrate) (P3HB). Notably, catalyst's strong kinetic preference for polymerizingrac‐8DLMeover 7‐HL in the 1/1 comonomer mixture rendered the formation of di‐block copolymer P3HB‐b‐P7HHp, showing two crystalline domains withTm1 ~ 65 °C andTm2 ~ 160 °C. Semi‐crystalline random copolymers withTmup to 164 °C have also been obtained by adjusting copolymerization conditions. Mechanical testing showed that P3HB‐b‐P7HHp can synergistically combine the high modulus of isotactic P3HB with the high ductility of P7HHp.

    Abstract Poly(p‐phenylene vinylene)s (PPVs) and poly(arylene vinylene)s are key materials for a variety of applications ranging from organic light emitting diodes to fluorescent optical probes. Their syntheses, however, have been hampered by non‐living or step‐growth polymerization techniques. The development of functional‐group tolerant olefin metathesis catalysts has enabled the use of living ring‐opening metathesis polymerization (ROMP) of cyclophane monomers yielding PPVs and poly(p‐phenylene‐co‐arylene vinylene)s in a living manner. Low dispersity and soluble PPVs are afforded with control over the number of repeat units with easy incorporation of different end‐groups at their heads or tails. In this review, a comprehensive overview of tetrasubstituted and disubstituted alkyl and alkoxy containing [2.2]paracyclophane‐1,9‐diene, [2.2]metaparacyclophane‐1,9‐diene, [2.2.2]paracyclophane‐1,9,17‐triene, and benzothiadiazole‐[2.2]paracyclophane‐1,9‐diene is provided. The high ring strain of these monomers enables efficient polymerizations with ruthenium initiators. A particular emphasis is on [2.2]paracyclophane‐1,9‐dienes as it is the most investigated class of polymerized cyclophanediene since initially reported 30 years ago. Additionally, applications for soft materials synthesized by ROMP are examined, highlighting easily accessed PPV copolymers and PPV block copolymers that can be phototriggered, as well as PPVs featuring supramolecular recognition units installed at their termini to afford orthogonally self‐assembled architectures.

    Background.Safe sensory-selective local anesthetics would be a major advance in the management of acute and chronic pain. Here we describe the sensory-selective local anesthetic properties and the toxicity profile of a known metabolite of amino-amide local anesthetics,2',6'-pipecolylxylidine (PPX). Methods.PPX was synthesized and made into its hydrochloride salt. PPX or ropivacaine (ROP) were injected at the sciatic nerve or intrathecally in rats, who then underwent modified hotplate (sensory) testing and weight-bearing (motor) testing. Rats injected with PPX or ROP were assessed for clinical toxicity endpoints. Conduction blockade was studied with single-unit recordings in mice. Biocompatibility was assessed histologically. Results.In male rats, sciatic sensory and motor block from 15 mM ROP lasted ~150 min; sensory nerve block from 30 mM PPX lasted 67.4 ± 17.4 min without motor block. Addition of chemical permeation enhancers to 30 mM PPX abolished sensory selectivity. Intrathecal 15 mM ROP produced sensory and motor block lasting ~15 min; sensory block from 30 mM PPX lasted 24.8 ± 8.7 min without motor block; repeated injection caused continuous sensory-selective block. In female rats, sciatic nerve blocks with ROP were similar to blocks in males, while blocks with PPX were sensory-selective but higher PPX concentrations were required. Ex vivo, 1.5 mM ROP caused reversible block of Aδ and C-fibers; 15 mM PPX blocked Aδ- but not C-fibers. Systemic 39.0 ± 1.8 mg/kg ROP caused severe clinical toxicity; 75.3 ± 3.2 mg/kg PPX caused none. Tissue reaction to PPX was benign, comparable to that of ROP. Conclusions.PPX provides sensory-selective local and neuraxial anesthesia with a good safety profile. The sensory selectivity may be attributable to the particular hydrophilic-hydrophobic balance of PPX.

    Abstract Polymerization‐induced self‐assembly (PISA) has emerged as a scalable one‐pot technique to prepare block copolymer (BCP) nanoparticles. Recently, a PISA process, that results in poly(l‐lactide)‐b‐poly(ethylene glycol) BCP nanoparticles coined ring‐opening polymerization (ROP)‐induced crystallization‐driven self‐assembly (ROPI‐CDSA), was developed. The resulting nanorods demonstrate a strong propensity for aggregation, resulting in the formation of 2D sheets and 3D networks. This article reports the synthesis of poly(N,N‐dimethyl acrylamide)‐b‐poly(l)‐lactide BCP nanoparticles by ROPI‐CDSA, utilizing a two‐step, one‐pot approach. A dual‐functionalized photoiniferter is first used for controlled radical polymerization of the acrylamido‐based monomer, and the resulting polymer serves as a macroinitiator for organocatalyzed ROP to form the solvophobic polyester block. The resulting nanorods are highly stable and display anisotropy at higher molecular weights (>12k Da) and concentrations (>20% solids) than the previous report. This development expands the chemical scope of ROPI‐CDSA BCPs and provides readily accessible nanorods made with biocompatible materials.
