- Knitting rigid aromatic building blocks using a novel external crosslinker.
- The knitting hypercrosslinked conjugated microporous polymers (HCCMPs).
- HCCMPs have good luminescence properties and high electrical conductivity.
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 800Â m2Â gâ1, which also show comparable gas uptake properties reaching 1.14Â wt. % H2 adsorption at 1.13Â bar/77Â K, and 12.72Â wt. % CO2 adsorption at 1.13Â bar/273Â K, respectively. The extended Ï-conjugated structure and the three-dimensional network of Ï-Ï stacked aryl rings enable these HCCMPs good luminescence properties and high electrical conductivity.
