The large PAH discotic molecule PN8 based on HAT shows significant optical changes for colorimetric and fluorometric sensing of Cu2+ and Zn2+, with good selectivity and low detection limit. Additionally, PN8 can effectively adsorb Cu2+ and Zn2+ from wastewater.
A HAT based large PAH discotic molecule PN8 is developed. The enlarged chromophoric core and doping heteroatoms enable colorimetric and fluorometric sensing of Cu2+ and Zn2+ with highly appreciable optical changes, good selectivity and low detection limit. Moreover, PN8 was demonstrated as an excellent adsorbent to remove Cu2+ and Zn2+ from wastewater.
