WebDec 14, 2024 · Five new binary co-crystals have been prepared through molecular self-assembly of π-electron-rich molecules, such as phenanthrene, benzo[c]cinnoline, and phenazine, in the presence of π-electron-deficient molecules, such as tetrafluoro-1,4-benzoquinone, tetrachloro-1,4-benzoquinone, and 1,2,4,5-tetracyanobenzene, taken in … WebApr 5, 2024 · Chromism. In chemistry, chromism is a process that induces a change, often reversible, in the colors of compounds. In most cases, chromism is based on a change in the electron states of molecules, especially the π- or d-electron state, so this phenomenon is induced by various external stimuli which can alter the electron density of substances ... smith \u0026 warren badge company
