Short Abstract:
This Ph.D. thesis introduces two unconventional methodologies in organic reticular materials: rapid bottom-up synthesis an d programmed top-down disassembly. \;
First\, it presents an aco ustomicrofluidic platform utilizing surface-reflected bulk waves (SRBWs) t o accelerate the condensation of covalent organic frameworks (COFs) under ambient conditions within seconds. This technique enables the direct\, uni form deposition of crystalline COF thin films onto heat-sensitive\, non-pl anar\, and living biological substrates -such as plant leaves- serving as a protective ultraviolet shield without compromising cellular viability.&n bsp\;
Second\, the thesis pioneers "clip-off chemistry" in pure orga nic reticular materials. By systematically evaluating the ozone resilience of various covalent linkages\, stable amide and polyimide backbones were selected as linkages for the material design. Rationally designed 2D COFs containing cleavable olefinic junctions underwent controlled ozonolysis\, achieving the selective and high-yield excision of complex hexagonal macro cycles. Together\, these methodologies transform COFs from passive powders into dynamic platforms for advanced surface engineering and streamlined m olecular synthesis. \;
