N,N′-bicarbazole-benzothiadiazole-based conjugated porous organic polymer for reactive oxygen species generation in live cells

Abstract

A π-conjugated porous organic polymer (BCzBz) was fabricated employing N,N'-bicarbazole and benzothiadiazole as molecular building units exhibiting broad visible light absorption. The photostable, water-dispersible, and cytocompatible BCzBz was demonstrated as...

Vinylene-bridged donor–acceptor type porous organic polymers for enhanced photocatalysis of amine oxidative coupling reactions under visible light

“…Then, electron paramagnetic resonance (EPR) measurements were performed to trap the involved reactive species of O 2 ˙ − and 1 O 2 by using 5,5-dimethyl-1-pyrroline- N -oxide (DMPO) and 2,2,6,6-tetramethylpiperidine (TEMP). 17 As expected, both O 2 ˙ − and 1 O 2 characteristic signals of adducts with DMPO and TEMP were observed in EPR spectra upon the irradiation of TpTc-POP in CH 3 CN solution, respectively (Fig. S9 in ESI † ).…”

The order–disorder conundrum: a trade-off between crystalline and amorphous porous organic polymers for task-specific applications

“…The generation of reactive oxygen species (ROS) like singlet oxygen, superoxide anion radicals, and hydroxyl radicals has garnered signicant attention in the photodegradation of organic micropollutants and photochemical transformations along with application in photodynamic therapy. [203][204][205] Both amorphous POPs and crystalline COFs have been reported for ROS-mediated photocatalysis owing to their unique structural features, which are critically discussed here.…”

Porous Organic Polymers: Promising Testbed for Heterogeneous Reactive Oxygen Species Mediated Photocatalysis and Nonredox CO2 Fixation

“…The photo-induced ROS generation inside the cell by BCzBz holds promise for further exploration of conjugated POPs in photodynamic therapy. [85]…”
