Poly(3-hexylthio) thiophene Field-effect Transistor Device Performance: Impact of the Content of Hexylthio Side Chain on Backbone

引用

Chinese Journal of Polymer Science 2024年第1期42卷 14-23,I0005页

作者： Hao-Yu Liu lian-He Han Ling-Wei Kong Li-Ping Zhu Xiao-Lan Qiao mei-Fang Zhu State Key Laboratory for Modification of Chemical Fibers and Polymer Materials College of Materials Science and EngineeringDonghua UniversityShanghai 201620China School of Electronic Information and Electrical Engineering Shanghai Jiao Tong UniversityShanghai 200240China

Regioregular poly(3-hexylthio)thiopene(P3HTT) has emerged tremendous potential in organic electronic applications due to the strong noncovalent interactions from the sulfur atom linked to thiophene. However, P3HTT generally exhibits low charge mobility mostly due to poor solution processability attributed to dense arrangement of hexylthio side chain in polymer, which led to strong noncovalent interactions among sulfur atoms. To balance the nonvalent interaction and aggregation for P3HTT, herein, we systematically study the effect of hexylthio side chain content in polymer backbone on the structure and properties. A series of regioregular P3HTT-based homopolymers(P3HTT, P3HTT-50,P3HTT-33 and P3HTT-25) were prepared via Kumada catalyst transfer polycondensation method from a set of mono-, bi-, ter-and quarterthiophenes containing different contents of hexylthio side chain. The DFT calculation shows the planarity of polymers backbone could be improved through reducing the density of hexylthio side chain in polymer mainchain. And significant changes in their crystallinity, aggregation and optical properties were observed with the content of hexylthio side chain reducing. The P3HTT-33 displayed the highest field-effect transistor hole mobility of 2.83×10^(-2) cm^(2)·V^(-1)·s^(-1) resulting from a balance between the crystallinity and planarity. This study demonstrates modulating the content of hexylthio side chain in P3HTT is an effective strategy to optimize the opto-electronic properties of polymer obtaining excellent semiconductor device performance.

Thyroid nodules are a common clinical problem caused by various factors,including environmental and nutritional factors and genetic *** environment can modulate and influence not only the risk of thyroid nodules but also the severity of disease in humans[1].The environment is awash with elements,and all mineral elements,including heavy metals and trace elements,are considered potentially toxic.A significantly higher incidence of thyroid cancer has been reported in populations exposed to low doses of metallic elements in volcanic areas over a long period[2].As research on thyroid disorders continues,it is becoming clear that abnormalities in trace elements in the body can affect the development of thyroid-related disorders.

Objective To investigate molecular characterization of streptococcus pyogenes isolates involved in an outbreak of scarlet fever in China in 2011. Methods Seventy-four 5treptococcol pyogenes involved in an outbreak of scarlet fever were isolated from pediatric patients in the areas with high incidence in China from May to August of 2011. Emm genotyping, pulsed-field gel electrophoresis （PFGE）, superantigen （SAg） genes and antimicrobial susceptibility profiling were analyzed for these isolates. Results A total of 4 different emm types were identified. Emm12 was the most prevalent type which contained four predominating PFGE patterns corresponding to four different virulence and superantigen profiles. Emm12（79.7%） and emml （14.9%） accounted for approximately 94% of all the isolates. The speA gene was all negative in emm12 isolates and positive in emml isolates. All strains were resistant to erythromycin, and 89.4% of them were resistant to erythromycin, tracycline, and clindamycin simultaneously. Conclusion Several highly diversified clones with a high macrolide resistance rate comprise a predominant proportion of circulating strains, though no new emm type was found in this outbreak. The data provide a baseline for further surveillance of scarlet fever, which may contribute to the explanation of the outbreak and development of a GAS vaccine in China.

目的沐舒坦具有促进肺表面活性物质合成和分泌的作用。近年来已有较多学者将其用于预防早产儿呼吸窘迫综合征(RDS),取得了较好的临床疗效。该研究旨在比较静脉和雾化两种不同途径使用沐舒坦预防早产儿RDS的疗效。方法将我院产科出生的早产儿(胎龄28～37周)随机分为静脉给药组、雾化吸入组两个用药组及未用沐舒坦的对照组,静脉给药组于出生后立即从脐静脉注射沐舒坦15mg/kg,随后静脉点滴每日30mg/kg,分2次给药;雾化给药组给予氧气驱动雾化吸入沐舒坦每日30mg/kg,分2次给药,均用药2d;对照组不使用沐舒坦。比较3组RDS的发生率、并发症及住院6h血气分析结果。结果①静脉给药组RDS的发生率为7.5%,雾化给药组为5.0%,对照组为24.4%,两用药组间比较差异无显著性,但均低于对照组(P<0.05)。②两用药组住院6h的血气分析结果与对照组比较差异有显著性(P<0.05),两用药组间比较差异无显著性。③两用药组并发症发生率明显低于对照组(P<0.05),两用药组间比较差异无显著性。结论新生儿早期使用沐舒坦预防RDS,具有一定疗效,无论是经静脉还是雾化给药,均能获得相同的效果。
