Abstract
The development of new and efficient polymerization strategies for the construction of functional polymers is of great significance in both academic and technological fields. Unlike conventional polymerizations of olefins or the condensation polymerizations of single-bond monomers, polymerizations based on triple-bond building blocks can produce functional polymers with electronically unsaturated double/triple bonds, fused rings, and heterocycles, etc. These unique constructing units endow the acetylenic polymers with interesting optoelectronic properties and advanced functionalities.

The development of new and efficient polymerization strategies for the construction of functional polymers is of great significance in both academic and technological fields. Unlike conventional polymerizations of olefins or the condensation polymerizations of single-bond monomers, polymerizations based on triple-bond building blocks can produce functional polymers with electronically unsaturated double/triple bonds, fused rings, and heterocycles, etc. These unique constructing units endow the acetylenic polymers with interesting optoelectronic properties and advanced functionalities.
The main objective of this thesis is to expand the family of functional polymers based on triple-bond building blocks by developing facile and powerful polymerizations from the reported organic reactions and explore their high-tech applications. Herein, several alkyne-based polymerization reactions with practical applications have been successfully developed, including (1) in situ generation of azonia-containing polyelectrolytes for luminescent photopatterning and superbug killing, (2) multicomponent polyannulation for the synthesis of heteroaromatic hyperbranched polyelectrolytes that could be utilized for customizable living biopattern fabrication, (3) photoresponsive polysulfonates with multifunctionalities constructed by catalyst-free polymerization with 100% atom economy, and (4) in situ generation of polyfulvenes by [2 + 2 + 1] polymerization of internal diynes and alkenyl iodides.
