The development of novel alkyne-based polymerization strategies towards advanced functional materials are of great importance both in academic field and industrial implication. In this thesis work, I launched a program for developing multicomponent polymerizations from corresponding facile small molecular reactions and exploring their potential applications as advanced polymeric materials. The novel alkyne-based polymerizations have been successfully in Chapters II-VI: (1) Pd-catalyzed regio- and stereo-selective polymerizations of terminal diynes and CuBr₂; (2) One-Pot Pd-catalyzed multicomponent polymerization of terminal diynes, phenyl boronic acids and diiodides; (3) Cu-catalyzed regio- and stereo-selective polymerizations of diynes, 4,4'–oxybis(benzenesulfonyl hydrazide) a...[ Read more ]

The development of novel alkyne-based polymerization strategies towards advanced functional materials are of great importance both in academic field and industrial implication. In this thesis work, I launched a program for developing multicomponent polymerizations from corresponding facile small molecular reactions and exploring their potential applications as advanced polymeric materials. The novel alkyne-based polymerizations have been successfully in Chapters II-VI: (1) Pd-catalyzed regio- and stereo-selective polymerizations of terminal diynes and CuBr₂; (2) One-Pot Pd-catalyzed multicomponent polymerization of terminal diynes, phenyl boronic acids and diiodides; (3) Cu-catalyzed regio- and stereo-selective polymerizations of diynes, 4,4'–oxybis(benzenesulfonyl hydrazide) and diphenyl dichalcogen; (4) Catalyst-free polymerization of inorganic K₂S and internal diynes; (5) Pd-catalyzed oxidative polyannulation of internal diynes and 1-methylpyrazole.

The major tasks of this thesis are design of monomers, optimization of polymerization conditions, structural characterization and performance testing of obtained polymeric products and exploring potential applications. These resulting macromolecules enjoyed high molecular weights (M_w up to 915,900) in satisfactory yields (up to 95.3 %). The structures and properties of the polymers are carefully characterized and evaluated by standard spectroscopic techniques, such as IR, NMR, GPC, MS, TGA, DSC, UV, PL and RI analyses. All the polymers owned good processability and thus can be applied in real-world applications. Versatile functionalities such as high structural regio- and stereo-selectivity, aggregation-induced/enhanced emission characteristics, good thermal stability, post-functionality, lysosome-specific staining ability, redox property, fluorescent patterning and high and tunable light refractivity were successfully achieved by smart design and patient research. Macromolecules obsessed with multi-functionalities are believed to be promising candidate as advanced polymeric materials.
