A new series of hypercrosslinked polymers were efficiently synthesized by knitting rigid aromatic building blocks using a novel external crosslinker (1,4-dimethoxybenzene, DMB) which result in a conjugated microporous structure. This knitting hypercrosslinked conjugated microporous polymers (HCCMPs) are predominantly microporous and exhibit high surface area of up to 800 m(2) g(-1), which also show comparable gas uptake properties reaching 1.14 wt. % H-2 adsorption at 1.13 bar/77 K, and 12.72 wt. % CO2 adsorption at 1.13 bar/273 K, respectively. The extended pi-conjugated structure and the three-dimensional network of pi-pi stacked aryl rings enable these HCCMPs good luminescence properties and high electrical conductivity.
