Liquid crystalline 3,4:9,10-perylenetetacarbocylic acid diimides

Abstract

Perylene-3,4:9,10-tetracarboxylic diimides of the general formula I where R1, R2, R3 and R4 are independently hydrogen, chlorine, bromine or substituted or unsubstituted aryloxy, arylthio, arylamino, hetaryloxy or hetarylthio; R5, R6, R7, R8, R9 and R10 are independently hydrogen or long-chain alkyl, alkoxy or alkylthio whose carbon chain may in each case contain up to four double bonds, with the proviso that at least four of these radicals are not hydrogen are prepared and used as liquid-crystalline materials for electronic, optoelectronic and photonic applications, for coloration of macromolecular organic and of inorganic materials, as fluorescent dyes and as laser dyes and also as organic materials for solar collectors and electroluminescence applications.
