Abstract

The present invention related to a dye comprising a chromophore to which an acyloin group as anchoring group is attached, to a method of synthesis of such dye, to an electronic device comprising such dye and to the use of such dye.

First claim

The invention claimed is:

1. An electric device, comprising a dye and a photoactive semiconductor porous material, wherein the dye comprising a chromophore to which an acyloin group is attached, and represented by formula (2e)

wherein said chromophore absorbs electromagnetic radiation in a range from 300-1200 nm and is

wherein X′ is C,
Z is one or more moieties which, at each occurrence, is independently selected from the group consisting of H, a cyclic alkyl, an acyclic alkyl, a straight or branched chain moiety of formula —(CH 2 ) n1 —R, —[(CR═CR) n1 —(CH 2 ) n2 ] p —R, —[(C═C) n1 —(CH 2 ) n2 ] p —R, —[(CH 2 ) n1 —X n2 ] p —R, a halogen, a substituted phenyl, an unsubstituted phenyl, a substituted biphenyl, an unsubstituted biphenyl, and an unsubstituted heteroaryl, n′ 32 1, n1 and n2=0-12 and p=0-6,
wherein X is CR 2 , O, S or NR,
wherein R is selected from the group consisting of H, a straight or branched alkyl chain of formula —C n H 2n+1 , —COOR 1 , —OR 1 , —SR 1 , —NR 1 2 , F, Cl, Br, I, CN, and CF 3 ;

wherein R 1 is H, a straight or branched alkyl chain of formula —C n H 2n+1 , a substituted or non-substituted phenyl or biphenyl or heteroaryl, and n=1-12.
