Abstract

Structurally simple aromatic hydrocarbons that possess only one isocyano group show luminescent mechanochromism. The structural isomers of these aromatic hydrocarbons exhibit blue- and red-shifted emission bands upon mechanical stress. Their low molecular weight enables their sublimation under mild conditions.

摘要

仅含有一个异氰基的结构简单的芳香烃呈现出发光机械变色现象。这些芳香烃的结构异构体在机械应力作用下会出现发射带蓝移和红移的现象。它们的低分子量使其能够在温和条件下升华。
