Abstract

Abstract : Fully π-conjugated sp 2 carbon covalent organic frameworks upon anchoring carboxylic electrolyte sites on the pore wall become highly luminescent label-free dual-channel quantitative detectors. Abstract : Fully π-conjugated sp 2 carbon covalent organic frameworks upon integration with carboxylic electrolyte sites on the pore wall become highly luminescent sensors. The sensors feature dual channel responsiveness and are able to detect both acids and bases over a wide pH range and the neurotransmitter dopamine via ultrafast electron transfer under ambient conditions.
