Abstract
The development of new and efficient polymerization routes for the construction of novel
functional polymers is of great significance in both academic and technological fields. Unlike
conventional polyolefins or condensation polymers, acetylenic polymers generally possess
unique π-conjugated electronic structure, which endow them with interesting photophysical
properties and advanced functionalities.
The main objective of this thesis is to design and synthesize new functional acetylenic
polymers with good solubility and high molecular weights by developing facile and powerful
polymerization routes from the reported alkyne-based organic reactions. To achieve this goal,
diverse monomers have been prepared and the polymerization conditions were systematically
optimized. The struct...[

The development of new and efficient polymerization routes for the construction of novel
functional polymers is of great significance in both academic and technological fields. Unlike
conventional polyolefins or condensation polymers, acetylenic polymers generally possess
unique π-conjugated electronic structure, which endow them with interesting photophysical
properties and advanced functionalities.
The main objective of this thesis is to design and synthesize new functional acetylenic
polymers with good solubility and high molecular weights by developing facile and powerful
polymerization routes from the reported alkyne-based organic reactions. To achieve this goal,
diverse monomers have been prepared and the polymerization conditions were systematically
optimized. The structures and properties of the obtained polymers were carefully
characterized and investigated using various techniques, such as GPC, IR, NMR, TGA, DSC,
UV, PL, XPS, RI, SEM, fluorescent microscope, DFT theoretical calculations, etc. The
potential applications of the obtained polymers in various fields were also explored.
In this thesis, four different two-component polymerization routes of aromatic monomers
and internal alkynes have been developed to synthesize various functional polymers with
fused aromatic rings. Meanwhile, an efficient multicomponent polymerization route with
terminal alkyne as one of the monomers was developed to construct unconventional
luminescent polymers with readily openable small heterocycles. The obtained polymers
generally possess excellent solubility, good thermal stability and film-forming ability, high
refractive index, and low chromatic dispersion. Some polymers exhibit unique
aggregation-induced emission (AIE) properties and can be used for the fabrication of
fluorescent photopatterns and for bioimaging applications. Besides, an interesting project on
the utilization of fluorescent AIE probes for the high-contrast visualization and differentiation
of microphase separation in polymer blends was also described herein.
