PHOTOCHROMISM. SYNTHESIS AND PROPERTIES OF INDOLINOSPIROBENZOTHIOPYRANS
Novel photochromic compounds, indolinospirobenzothiopyrans, were prepared and their properties in polymer films were examined.The absorption bands of the colored form lie around 100 nm deeper in the long-wave region of the spectrum than are the case with the common spiropyrans.
