Pentacenequinone derivatives: aggregation-induced emission enhancement, mechanism and fluorescent aggregates for superamplified detection of nitroaromatic explosives
Suzuki–Miyaura coupling protocol. These derivatives form fluorescent aggregates in mixed aqueous media due to their aggregation-inducedemissionenhancement (AIEE) attributes. Interestingly, size dependent emissionenhancement is observed in the case of derivatives 5–7 and the effect of increase in the number of pyridine rotors on fluorescenceemission of pentacenequinone derivatives 6–7 in solution and
We have designed and synthesized pentacenequinone/pentacenequinodimethane derivatives 3, 4 and 6 having nitrile groups using Suzuki–Miyaura coupling and Knoevenagel condensation protocols.
