Soluble conjugated alternating porphyrin−dithienothiophene copolymers—single-bond linked (I) and triple-bond (IIa IIb)—were synthesized by palladium(0)-catalyzed Stille Sonagashira coupling reactions, respectively. The thermal, electrochemical, optical, charge transport, photovoltaic properties of these copolymers were examined; the effect triple bond was studied. I exhibits onset decomposition temperature (Td) 410 °C glass-transition (Tg) 180 °C, higher than those IIb (Td, 330 °C; Tg, 130...
Abstract All‐small‐molecule organic solar cells (ASM‐OSCs) are challenging for their inadequate efficiency and device stability due to more susceptive morphology. Herein, a family of isomeric small molecule donors (SMDs) is synthesized based on the benzodithiophene–terthiophene core with linear, 1st carbon, 2nd carbon position branched butyl‐based rhodanine ASM‐OSCs, respectively. The single crystal thiophene‐substituted model T‐ s ‐Bu forms compact intermolecular packing herringbone...
Typically dealing with practical samples very complex matrices, ambient ionization mass spectrometry suffers from low detection sensitivity. In this study, molecular imprinting technology was explored and integrated the membrane electrospray (MESI) method for direct sample analyses. By enriching targeted analytes on molecularly imprinted membranes (MIMs), improvement (by 10- to 50-fold) in limit of quantitation could be achieved, compared conventional nanoelectrospray methods or other...
Gene mining is crucial for understanding the regulatory mechanisms underlying complex biological processes, particularly in plants responding to environmental conditions. Traditional machine learning methods, while useful, often overlook important gene relationships due their reliance on manual feature selection and limited ability capture inter-gene dynamics. Deep approaches, powerful, are unsuitable small sample sizes. This study introduces TransGeneSelector, first deep framework...
Two soluble phthalocyanine derivatives, 2,9,16-tri(tert-butyl)-23-(10-hydroxydecyloxy) (1) and copper (2) were used as semiconductor layers in organic thin-film transistors (OTFTs) based on their Langmuir−Blodgett (LB) films. From the π−A curves, we can conclude that 1 2 molecules are a titled arrangement at air−water interface. The molecular ordering LB multilayer films SiO2 substrate was examined by using UV−Vis absorption spectra atomic force microscopy (AFM). highest occupied orbital...

Two new TBT-based stationary phases (TBT-AA, TBT-AC12) exhibited high-resolution performance for aliphatic and aromatic isomers.
meso and rac isomers of (η5:η5-C5H4RMeSiSiMeRC5H4)Fe2(CO)2(μ-CO)2 (R = Ph, n-Bu) were synthesized successfully separated for the first time.
