In this work, we focuse on investigating the optoelectronic and mechanical properties of polyfluorene-based blue LCPs, of which the polymer side chains were straight alkyl chains (octyl) and branched alkyl chains (2-hexyldecyl). Comparatively, the solution processed film of polymer with branched alkyl chains performed substantially improved photoluminescence quantum yield (PLQY) from 18.9% to 46.5%. Benefiting from the internal plasticization of branched alkyl chains, the elastic modulus of polymer film reduced from 350 Mpa to 180 Mpa, confirming the validity of enhancing alkyl/π ratio in lowering film stiffness and necessity for characterzing the intrinsic mechanical properties. Finally, polymer light-emitting diodes (PLED) that performed stable blue emitting was achieved with the polyfluorene-based LCPs functionalized by branched alkyl chains. Overall, these observations manifest the feasibility of side-chain branching in tuning the mechanical properties of LCPs, and provide a deep insights for developing intrinsic stretchable semiconductors.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141597361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, phenyl-substituted diene monomer structures have been hardly investigated. Based on DFT-calculations and 13C NMR spectroscopy, a discrepancy in the reactivity of the two monomers 1-phenyl isoprene (1PhI) and 4-phenyl isoprene (4PhI) in the anionic polymerization is expected. Starting from a Wittig reaction including an optimized extraction procedure, the disubstituted 1,3-dienes resulted in polymers with different prevalence of 1,3-incorporation. The polymers have been characterized by 1H NMR spectroscopy and using different SEC conditions. Molecular weights up to 48.8 kg mol-1 with narrow dispersities (Đ ≤ 1.13) were achieved. The addition of the modifier THF led to an initial increase of vinyl-units as well as a loss of control for the polymerization of 4PhI. Increasing the THF concentration further resulted in a rather unusual decrease of the vinyl units and climaxed in more than 80% 1,4-units in pure THF. Copolymerizations with styrene (S) and isoprene (I), respectively, were tracked via in situ 1H NMR kinetics. The observed ideally random copolymerization of I and 1PhI as well as the gradient copolymers with S were further investigated via the synthesis of copolymers with a targeted Mn of 40 kg mol-1. In a subsequent reaction step, the homopolymers were cyclized using trifluoromethyl sulfonic acid inducing fluorescent properties. The different microstructure and substitution pattern of the original polymers differ in both emission maximum and quantum yields.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141566089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant progress in this area has been achieved with a variety of homogeneous transition-metal catalysts. However, few examples of heterogeneous catalysis of direct C-H bond transformation have been reported. In this work, we report a new type of α-diimine structure functionalized conjugated microporous polymers (DIM-CMP) used as ligand for heterogeneous catalysis, which shows high efficiency and recyclability for the Pd-catalyzed direct C-H arylation. These DIM-CMPs are distinguished by their exceptional stability, robust porous framework, and efficacious allocation of palladium active sites, all of which cumulatively contribute to their superior catalytic performance. The superior utility of DIM-Pd-CMP in catalysis was elucidated by the broad substrate scopes (32 examples, 82-98% yields), along with the tolerance of a variety of functional groups, good recyclability (6 times) and proven on a gram scale (10 mmol). Moreover, its utility has been highlighted in the synthesis of potentially bioactive molecule through sequential C-H arylation and Suzuki coupling. This innovative development is poised to significantly impact the synthesis of heterobiaryls, crucial constituents in a variety of natural products and pharmaceutical compounds, potentially revolutionizing catalysis in industrial applications and offering significant economic and environmental advantages.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141561203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While Janus micelles have been extensively studied, e.g. as compatibilizers in polymer blends, there are hardly any reports on the use of patchy micelles. In this study, we show that spherical micelles with a polylactide stereocomplex (SC) core and a patch-like microphase separated polystyrene/poly(<em>tert</em>-butyl methacrylate) (PS/P<em>t</em>BMA) corona are efficient compatibilizers for highly immiscible PS/P<em>t</em>BMA blends. The patchy SC micelles, prepared by stereocomplex-driven self-assembly (SCDSA) of enantiomeric diblock copolymers, improved the homogeneity of the blends and led to a significant reduction of the PS droplet size. We further employed SCDSA to selectively incorporate a fluorescent dye inside the SC micelle core without changing the shape or chemistry of the patchy corona. This allows the use of confocal scanning fluorescence microscopy to localize the patchy SC micelles, being predominantly assembled at the PS/P<em>t</em>BMA blend interface. Interestingly, the reduction in PS droplet size was comparable for blends compatibilized with patchy SC micelles and Janus micelles, but only for patchy SC micelles a monomodal droplet size distribution could be achieved. The outstanding interfacial activity of the patchy SC micelles can be attributed to their adaptive corona structure, resulting in a selective swelling/collapse of the respective miscible/immiscible corona patches at the blend inter¬face.","PeriodicalId":100,"journal":{"name":"Polymer Chemistry","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141566083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
