Black polyimide (BPI) is increasingly in demand for the development of photoelectric devices place yellow transparent polyimide, but BPI doped with carbon black shows serious insulation and mechanical performance deficiencies due to pinholes uneven dispersion. Intrinsically has thus attracted increasing interest science industry. Anthraquinone derivatives have an ample high molar extinction coefficient (ε), appending as many auxochromes (−OH −NH2) possible on anthraquinone skeleton can...

Chiral expression from the molecular to macromolecular level, as well aggregates, plays an important role in natural physiological activity. Therefore, understanding chirality transfer mechanism will provide guidance for design of new functional chiral materials. Herein, we have systematically investigated assembly and morphological level liquid crystalline block copolymers (LC-BCPs) induced by enantiopure tartaric acid (TA) a source. Both experimental theoretical results indicate that...

The quality of Supervised Fine-Tuning (SFT) data plays a critical role in enhancing the conversational capabilities Large Language Models (LLMs). However, as LLMs become more advanced, availability high-quality human-annotated SFT has significant bottleneck, necessitating greater reliance on synthetic training data. In this work, we introduce Condor, novel two-stage generation framework that incorporates World Knowledge Tree and Self-Reflection Refinement to produce at scale. Our...

Abstract With the rapid development of flexible displays and wearable electronics, there are a substantial demand for colorless transparent polyimide (CPI) films with different properties. Traditional trial‐and‐error experimental methods time‐consuming costly, density functional theory based prediction HOMO‐LUMO gap energy also takes time is prone to varying degrees error. Inspired by machine learning (ML) applications in molecular materials science, this paper proposed data‐driven ML...

While LLM-Based agents, which use external tools to solve complex problems, have made significant progress, benchmarking their ability is challenging, thereby hindering a clear understanding of limitations. In this paper, we propose an interactive evaluation framework, named CIBench, comprehensively assess LLMs' utilize code interpreters for data science tasks. Our framework includes dataset and two modes. The constructed using LLM-human cooperative approach simulates authentic workflow by...
