ABSTRACT:
This application is directed to optoelectronic materials which are bistable organic tautomeric compositions of dithio or diseleno carbamate esters of cyclic 1,3-dithia or -diselena-2-iminium salts. Specifically, it is concerned with compounds having the formula: ##STR1## Wherein X is S or Se; wherein R or R.sub.1 are alkyl, or alkyl that together form a ring of carbon atoms; wherein An is the anion of a strong acid. These molecules are in themselves molecular-sized optoelectric switching devices.
