Smart covalent organic frameworks: dual channel sensors for acids and bases

Fully pi-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.

Automated summary

Integration of carboxylic electrolyte sites onto sp(2) carbon covalent organic frameworks results in highly luminescent sensors that exhibit dual channel responsiveness and can detect acids, bases, and the neurotransmitter dopamine via ultrafast electron transfer under ambient conditions.
