摘要:
The invention relates to a process for preparing a polyalkyl perylene which consists in subjecting the corresponding polyalkyl 1,1'-dinaphthalene derivative to a cyclodehydrogenation reaction, by means of an alkali metal. It also relates to the polyalkyl perylene obtained, and to the organic material derived therefrom exhibiting an electron spin resonance spectrum.
摘要:
Disclosed is an organic material with a very narrow electronic spin resonance (ESR) line. This material is formed by a 1, 2, 7, 8-tetrahydrocyclopentataperylene salt which may have, advantageously, undergone a heat treatment. The material can be applied to the fabrication of probes for gaussmeters and magnetometers.
