Hierarchical porous organic hyper-cross-linked polymers containing phthalazinone and carbazole moieties for gas uptake and fluorescence properties

[Display omitted] •Phthalazinone and carbazole groups were employed in construct hierarchical porous organic polymers by two methods.•These porous organic polymers exhibited high BET surface area, CO2 uptake capacity and selectivity.•The fluorescent polymers displayed high sensitivity and selectivit...
