A novel multifunctional initiator has been developed by peripheral modification of a Pt-acetylide dendrimer. Pd–Pt μ-ethynediyl
units were introduced to the first-generation dendrimer by a divergent method. The dendritic initiator was applicable to the
living polymerization of aryl isocyanides, producing high molecular weight polymers with a narrow polydispersity index in
quantitative yields. The 31P NMR spectrum of the resulting polymer suggested that all Pd–Pt μ-ethynediyl units in the dendritic molecule actually functioned
as an initiator. 相似文献

The purpose of this study is to suggest a conceptual model for sustainable communities, considering sustainable development and placemaking perspectives of community building in Korean apartment complexes. This study then verifies the validity of the model as an action plan. Based on a review of literature at home and abroad, the model was conceptualized on the structure of living programs and physical and social settings for sustainable communities in Korean apartment complexes. The living program, which connects physical and social settings, consists of four action subjects: Activation of community spaces, activation of community programs, activation of participation, and activation of ecological living and design. This model demonstrates that a living program will increase resident satisfaction and result in a sustainable community. Three subjects out of the four suggested in the living program of the model were empirically tested based on previous research data. According to the correlation analysis between living programs and residential satisfaction, when residents are satisfied with community spaces, programs, and participation in the community, overall residential satisfaction rises. Accordingly, the living program of the conceptual model plays a meaningful role in developing sustainable communities in Korean apartment complexes. 相似文献

This article summarizes recent examples for precise synthesis of (co)polymers containing functional end groups prepared by living ring-opening metathesis polymerization (ROMP) using molybdenum, ruthenium complex catalysts. In particular, this article reviews recent examples for synthesis of amphiphilic block/graft copolymers by adopting transition metal-catalyzed living ROMP technique. Unique characteristics of the living ROMP initiated by the molybdenum alkylidene complexes (so-called Schrock type catalyst), which accomplish precise control of the block segment (hydrophilic and hydrophobic) as well as exclusive introduction of functionalities at the polymer chain end, enable us to provide the synthesis of block copolymers varying different backbones by adopting the “grafting to” or the “grafting from” approach as well as “soluble” star shape polymers with controlled manner. The “grafting through” approach (polymerization of macromonomers) by the repetitive ROMP technique offers precise control of the amphiphilic block segments. 相似文献
