摘要

有机盐致变色（OHC）现象在卤化溶剂中引起染料光吸收带明显的异色或正色偏移。OHC的表达可归因于有机卤素与染料分子之间特定的分子间相互作用，包括卤素-阴离子相互作用（即卤素键）和卤素/π相互作用。对OHC的深入了解使我们能够创建一种光学光谱方法和功能染料材料，用于检测和可视化有毒挥发性有机卤素化合物。更多信息可以在Yousuke Ooyama及其同事的概念文章中找到（DOI: 10.1002/cptc.202400187）。

Front Cover: Organohalogenochromism: Toward Colorimetric Detection of Volatile Organic Halogen Compounds (ChemPhotoChem 1/2025)

The Front Cover illustrates organohalogenochromism (OHC) which induces a significant hypsochromic or bathochromic shift of photoabsorption band of dye in halogenated solvents. The expression of OHC would be ascribable to the specific intermolecular interaction between the organohalogen and the dye molecules, including halogen−anion interaction (i.e. halogen bond) and halogen/π interaction. The insight into the OHC allows us to create an optical spectroscopic method and functional dye material for detection and visualization of toxic volatile organohalogen compounds. More information can be found in the Concept article by Yousuke Ooyama and co-workers (DOI: 10.1002/cptc.202400187).
