The present invention relates to compounds of the formulae Ia and Ib
in which the variables R, n, A, B, R
1
and R
2
are each as defined in the description.
The present invention further relates to the use of compounds of the formula Ia or Ib or mixtures of compounds of the formulae Ia and Ib and/or isomers or mixtures of the isomers of the compounds of the formulae Ia and Ib as photosensitizers in solar cells and photodetectors, and to solar cells and photodetectors which comprise such compounds of the formula Ia or Ib or mixtures of compounds of the formulae Ia and Ib and/or isomers or mixtures of the isomers of the compounds of the formulae Ia and Ib as photosensitizers.

An efficient and functional group tolerant route to access hydroxy 1,8-naphthalimides has been used to synthesise a range of mono- and disubstituted hydroxy-1,8-naphthalimides with fluorescence emissions covering the visible spectrum. The dialkoxy substituted compounds prepared possess high quantum yields (up to 0.95) and long fluorescent lifetimes (up to 14 ns). The method has been used to generate
