The present invention provides the compounds of formulae (3) and (1) wherein n is 0 or 1, Rand Rare the same or different and are selected from the group consisting of NHR, NRR, OR, SRand R, or Rand Rtogether are selected from the group consisting of (a), (b) and (c), and X is CI, Br of I, and a process for the preparation of compounds of formula (3) comprising the compounds of formula (1) as key intermediates. 

Double donor functionalisation of the peri-positions of perylene and naphthalene monoimide via versatile building blocks

Boron-comprising perylene monoimides and a process for producing the boron-comprising perylene monoimides are provided. The boron-comprising perylene monoimides are useful as building blocks for producing perylene monoimide derivatives and monoimide derivatives. The boron-comprising perylene monoimides are also useful for preparing dye-sensitized solar cells.

Conveniently prepared naphthalene and perylene derivatives as building blocks for organic electronic materials and dyestuff

Thin layers or films of metal oxides are used as a semiconductor material of solar cells and they are coated with a sensitizer to achieve the high absorption of sunlight. Various dyes have been used as sensitizers in solar cells. Rylene monoimide derivatives are developed as photosensitizers for dye-sensitized solar cells and as photodetectors. The Rylene monoimide derivatives have very good quantum efficiencies, particularly in the NIR region of the absorption spectrum.
