Novel rapid room temperature synthesis of conjugated microporous polymer for metal-free photocatalytic degradation of fluoroquinolones

A physicochemical introspection of porous organic polymer photocatalysts for wastewater treatment

“…For example, studies on benzothiadiazole-or porphyrinoid-containing POPs generating 1 O 2 are prevalent that go by this combined route. 15 On the other hand, on multiple occasions, we have confirmed the substantial 1 O 2 generation ability of CPPs containing only benzene units, 94,95 and EEA seems the only feasible explanation for their activity.…”

“…We recently used an alternate and inexpensive sonochemical approach to synthesize photo-active POPs, where ultrasound assisted in the constrained growth of the material. 95 Such a defect-rich structure was able to generate a substantial amount of 1 O 2 for the rapid degradation of persistent antibiotics and pharmacophores. It is, however, important to note that a detailed analytical assessment of the POPs has not yet been done after their catalytic run.…”

New Approach in the Application of Conjugated Polymers: The Light-Activated Source of Versatile Singlet Oxygen Molecule

“…It has also been shown that the best photocatalytic properties were observed for the CMP containing -OH groups, which was assigned to the higher dispersity in water and more advantageous electronic structure, hence indicating that by careful design of the linker CMPs can strongly boost the performance of CMPs [143]. Recently, CMPs have also been effective as a light-activated sources of ROS in the degradation of antibiotics, such as fluoroquinolones [144]. [143]).…”

Advancement towards Antibiotic Remediation: Heterostructure and Composite materials

“…[92] One of the proposed pathways by Chakraborty and co-workers assumed piperazine ring dislocation in two ways: either the F atoms are replaced by À OH or the F units were intact in the skeleton which on further degradation generated simple amines. [91,93] LC-MS data was used to detect CO 2 , H 2 O, NO 3 À , F À as the mineralization products. [94] The degradation pathway is illustrated in Figure 7.…”

“…The obtained data indicated that the API along with its daughter products were mineralized in the final stage of photocatalysis [92] . One of the proposed pathways by Chakraborty and co‐workers assumed piperazine ring dislocation in two ways: either the F atoms are replaced by −OH or the F units were intact in the skeleton which on further degradation generated simple amines [91,93] .
