Abstract:
The present invention relates to naphthalenetetracarboxylic acid derivatives of the general formula (I) in which at least one of the radicals R1, R2, R3 and R4 stands for a substituent selected from Br, F and CN, and the remaining radicals stand for hydrogen; Y1 stands for O or NRa, with Ra standing for hydrogen or an organyl radical; Y2 stands for O or NRb, with Rb standing for hydrogen or an organyl radical; Z1 and Z2 independently of one another stand for O or NRc, with Rc standing for an organyl radical; and Z3 and Z4 independently of one another stand for O or NRd, with Rd standing for an organyl radical; to a process for preparing them and to their use, more particularly as n-type semiconductors.
Abstract:
The invention relates to fluorescent solar conversion cells based on one or more panels consisting of a polymer that is doped with a fluorescent dye and/or glass panels that are coated with a doped polymer and photovoltaic cells that are mounted on the edges of the panels. Said photovoltaic cells, contain one or more fluorescent dyes based on terylene carboxylic acid derivatives or a combination of said fluorescent dyes and additional fluorescent dyes.
Abstract:
The invention relates to a method for producing halogenated rylen-carboxymides of general formula (I), wherein variables have the following significance: A and B are jointly an imid residue or, when n is equal to 1, A and B are Hal or one is Hal residue and another a hydrogen residue, R and R' represent independently of each other hydrogen, optionally substituted alkyl, cycloalkyl, aryl or hetaryl; Hal represents chlorine, bromine or iodine; n is equal to 1, 2 or 3; x is equal to from 2 to 8. The inventive method consists in reacting a rylen-carboxymide of general formula (II), wherein A' and B' are together an imid residue or, when n is equal to 1, are together a hydrogen with an elementary halogen in the presence of an inert organic solvent L1 characterised in that a halogen hydrocide formed during the reaction is continuously removed from said L1 solvent.
