Conjugated network polymers (CNPs) have gained considerable attention as heterogeneous photocatalysts, however, their limited solubility in solvents poses a significant challenge employing CNPs for photoreactors. Herein, we report the chemical dissolution of aminic to enhance solution processability. The CNPs, synthesized via Knoevenagel polycondensation, were dissolved into corresponding polymer inks, forming thin films on various substrates through mild heating. Residual functional groups CNP surface provided latent reactive sites liquid amines, facilitating structural disentanglement and without hindering π-conjugation. resulting FTO electrodes exhibited broader light absorbance > 2-fold enhanced photoresponse compared powder films. Photocatalytic production H2O2 using large-area film (254.4 cm2) demonstrated sustained activity with rate 0.21 mM h−1 over 14 h sacrificial agents. These findings lay groundwork applying photocatalysts chemical, optical, electronic applications.

Circular RNAs (circRNAs), as a class of noncoding RNA molecules with circular structure exhibit high stability and spatiotemporal-specific expression, making them ideal cancer biomarkers for liquid biopsy. Herein, new photoelectrochemical (PEC) biosensor highly sensitive circRNA assay in the whole blood lung patients was designed based on CRISPR/Cas13a-programmed Cu nanoclusters (Cu NCs) Z-scheme covalent organic framework/silver sulfide (T-COF/Ag2S) composite. This T-COF/Ag2S composite accelerates electron transfer produces an excellent initial photocurrent. When CRISPR/Cas13a precisely targets circRNA, it nonspecifically cleaves triple-helix molecular to release DNA fragments (C'/C"). After C'/C" opens hairpin probe (HP) modified electrode, hybridization chain reactions are performed produce abundant AT-rich double-stranded addition H1 H2 probes. Upon incubation Cu2+, NCs situ formed via A-Cu2+-T bonds can effectively quench photocurrent due energy process. developed PEC shows low limit detection 0.5 fM, reusability DNA-modified magnetic beads (MB-DNA) reduces cost. Moreover, accurately quantify level distinguish expression from healthy controls patients, offering strong potential clinical diagnosis.
