Abstract


The review is devoted to mechanically sensitive indoline spiropyrans and their structural features. Recent advances in the study of their isomerization processes are considered, special attention is paid to the effect of pressure on the behavior of spiropyrans in the composition of various photochromic materials and dyes, as well as in the process of the formation of J-aggregates in Langmuir–Blodgett films.

Keywords


2H-chromenes, indolines, spiropyrans, barochromism, fluorescence, isomerization, mechanochromism, piezochromism.
