Article Abstract
The development of n-type organic semiconductors has evolved significantly slower in comparison to that of p-type organic semiconductors mainly due to the lack of electron-deficient building blocks with stability and processability. However, to realize a variety of organic optoelectronic devices, high-performance n-type polymer semiconductors are essential. Herein, conjugated microporous polymers (CMPs) comprising isoindigo acceptor units linked to benzene or pyrene donor units (BI and PI) showing n-type semiconducting behavior are reported. In addition, considering the challenges of deposition of a continuous and homogeneous thin film of CMPs for accurate Hall measurements, a plasma-assisted fabrication technique is developed to yield uniform thin films. The fully conjugated 2D networks in PI- and BI-CMP films display high electron mobility of 6.6 and 3.5 cm V s , respectively. The higher carrier concentration in PI results in high conductivity (5.3 mS cm ). Both experimental and computational studies are adequately combined to investigate structure-property relations for this intriguing class of materials in the context of organic electronics.

Background: Breast-conserving surgery (BCS) is the primary surgical approach for patients with breast cancer. The accurate determination of surgical margins during BCS is critical for patient prognosis; however, time constraints and limitations in current pathological techniques often prevent pathologists from performing this assessment intraoperatively. The inability to reliably assess margins during surgery can lead to incomplete tumor removal and the need for additional surgeries.

Simultaneous promotion of charge and mass transportation between catalytic centers and reactants is crucial for photocatalysis but remains a substantial challenge on account of the widespread use of homogeneous or heterogeneous photocatalysts that suffer from sluggish reactant-diffusion kinetics or interfacial electron-transport resistance, respectively. Herein, we demonstrate the construction of conjugated microporous polymer aerogels as available quasi-homogeneous photocatalysts by integrating structural designability, which allows for the incorporation of electron-acceptor building blocks featuring ultralong-lived excitons as high-concentration local catalytic centers, and hierarchically porous gel networks that wrap solvent and reactants to provide a "single" reaction phase without interfacial resistance. A total of 18 samples of C─H functionalization reactions underpinned by four different mechanisms were screened to showcase the general applicability of the obtained aerogel photocatalysts, which achieved remarkable conversion efficiencies, gram-scale productivities, and recyclability.

With mercury pollution causes serious threats to ecosystems and human health because of its extreme toxicity and bioaccumulation, the development of efficient removal technologies has become an urgent environmental priority. This study introduces a novel adsorbent thiazolo[5,4-d]thiazole conjugated microporous polymer (TzTzCMP) for efficient Hg(II) removal from wastewater. TzTzCMP synthesized via condensation of dithiocarbamate and triformyl-phenol, exhibits a coral-like porous structure with a high specific surface area of 436.

The development of efficient, metal-free photocatalysts for solar-driven CO reduction to methanol is promising for alleviating energy and environmental issues, but achieving high selectivity and conversion efficiency without sacrificial agents or co-catalysts remains a challenge. In this work, we report a series of acetylene-linked specialized donor-acceptor (D-A) type conjugated microporous polymers (CMPs) designed with tailored electronic structures to investigate their efficacy in photocatalytic CO reduction to methanol in an aqueous NaOH solution under visible light irradiation. Significantly, the optimized porous polymer TTT-DEBP, featuring a strong electron-accepting triazine ring and an extended π-conjugated diethynyl biphenyl (DEBP) system, achieved a higher CHOH production rate of 30.
