    Water-Soluble Multifunctional Cross-Conjugated Poly(<i>p</i>-phenylenes) as Stimuli-Responsive Materials:  Design, Synthesis, and Characterization

    No full text
    The design, synthesis, and characterization of a series of thermally stable water-soluble polymers with cross-conjugation and multiple functional groups are reported. All copolymers were characterized by means of FT-IR, GPC, 1H and 13C NMR, UV−vis, and fluorescence spectroscopy. Photophysical properties showed collective responses from their respective conjugated segments. Titration studies showed that such polymers have good sensitivity for both cationic and anionic quenchers in fluorescence decay, with an average Stern−Volmer constant of 105 M-1. Besides fluorescence quenching, significant shifts in absorption and emission maxima upon addition of small molecules were also observed. High concentration of small molecular quenchers induced aggregation of the polymers. All polymers were able to form highly fluorescent, flexible, free-standing thin films via evaporation of the solvent. Hence, by attaching cationic and anionic groups on a cross-conjugated water-soluble structure, a multifunctional CP system was developed for potential applications

    ObjectiveThis study investigated the impact of health resource enhancement on health and spatiotemporal variation characteristics from 2000 to 2010 at the county level.MethodsMultiscale Geographically Weighted Regression and curve fitting were used to explore the characteristics of spatiotemporal impact and divergence mechanism of health resource enhancement on population health.ResultsFrom 2000 to 2010, China's population health continued to rise steadily, and health resource allocation improved. Population health demonstrated the significant spatial autocorrelation, and its spatial clustering patterns were relatively fixed. Health resource allocation was relatively equal. Health technicians per 1,000 persons had a significant positive effect on population health in 2000 and 2010. Meanwhile, its impact tends to be consistent across regions, and the impact scale has been continuously expanding. A quantitative relationship exists between population health and health resource inputs. When life expectancy ranged from 73.68 to 84.08 years, the death rate ranged from 6.27 to 9.00%, and the infant mortality rate ranged from 0.00 to 6.33%, investments in health resources, especially related to health technicians, were beneficial for population health.ConclusionsThe government should improve the science and rationality of health resource planning. Planning meets regional realities by combining the impacts of economy and geography. The influence of health resources on population health depends on the overall allocation of health technicians. The number of health technicians needs to be further increased to improve the health resources' effective allocation between regions.</p

    Synthesis and Structure−Property Investigation of Polyarenes with Conjugated Side Chains

    A series of cross-conjugated polyarenes were synthesized and fully characterized. The polymers were soluble in common organic solvents and showed good thermal stability. Powder XRD showed ordered structures for all polymers and significant shift in the emission maxima with increasing concentration, indicating strong aggregation of polymer chains in solution. Solvatochromism studies showed blue shifts of absorption and fluorescence maxima in toluene as compared to the values in THF, suggesting that polymers tend to aggregation less or solvated more in toluene. A large two-photon absorption (TPA) cross section was observed for all polymers due to the unique molecular architectures. Fluorescence lifetime studies revealed that aggregation induced fast decay kinetics. Self-assembled helical nanofibers and nanorings were observed when casted films from polymer solutions. HRTEM and XRD investigation of the thin films revealed nanocrystalline structures of the polymers

    Syntheses and Properties of a Series of Cationic Water-Soluble Phthalocyanines

    No full text
    A series of symmetrical cationic phthalocyanines (Pcs) with either Zn(II) or Si(IV) metal ions and two bulky axial ligands on the silicon complexes was synthesized in high yields. The photophysical (absorption, emission, fluorescence, and singlet oxygen quantum yields) and cellular (uptake, toxicity, and subcellular localization) properties of this series of Pcs were investigated. The Si(IV)−Pcs exist mainly as monomers in aqueous media and have higher fluorescent quantum yields in protic solvents (methanol and water) than the Zn(II)−Pcs. The presence of eight short PEG groups at the periphery of a Zn(II)−Pc significantly increases its solubility in protic solvents, but a centrally chelated silicon ion and associated bulky axial ligands were more efficient in preventing aggregation of the Pc macrocycles. The singlet oxygen quantum yields for this series of Pcs in DMSO are in the range 0.09–0.15. All Pcs were readily taken up by human HEp2 cells, and the extent of their accumulation within cells depends on their hydrophobic character. Intracellularly, all Pcs localized preferentially within the cell lysosomes. The Zn(II)−Pc 11 and Si(IV)−Pcs 12 and 14 were found to be the most phototoxic (IC50 = 2.2 µM at a 1 J cm−2 light dose) of this series of compounds

    Data_Sheet_1_County level study of the interaction effect of PM2.5 and climate sustainability on mortality in China.docx

    IntroductionPM2.5 and climate change are two major public health concerns, with majority of the research on their interaction focused on the synergistic effect, particularly for extreme events such as hot or cold temperatures. The climate sustainability index (CLS) was introduced to comprehensively explore the impact of climate change and the interactive effect on human health with air pollution.MethodsIn this study, a county-level panel data in China was collected and used. The generalized additive model (GAM) and geographically and temporally weighted regression (GTWR) was used to explore the interactive and spatial effect on mortality between CLS and PM2.5.Results and discussionsIndividually, when CLS is higher than 150 or lower than 50, the mortality is higher. Moreover, when PM2.5 is more than 35 μg/m3, the influence on mortality is significantly increased as PM2.5 concentration rises; when PM2.5 is above 70 μg/m3, the trend is sharp. A nonlinear antagonistic effect between CLS and PM2.5 was found in this study, proving that the combined adverse health effects of climate change and air pollution, especially when CLS was lower (below 100) and PM2.5 was higher (above 35 μg/m3), the antagonistic effect was much stronger. From a spatial perspective, the impact of CLS and PM2.5 on mortality varies in different geographical regions. A negative and positive influence of CLS and PM2.5 was found in east China, especially in the northeastern and northern regions, -which were heavily polluted. This study illustrated that climate sustainability, at certain level, could mitigate the adverse health influence of air pollution, and provided a new perspective on health risk mitigation from pollution reduction and climate adaptation.</p
