Title
(EN) PHOTODETECTOR COMPOSITION
(FR) COMPOSITION DE PHOTODÉTECTEUR
Abstract
(EN)
A composition comprising a first compound and a second compound of formula (I) wherein EDG is an electron-donating group comprising a polycyclic hetero aromatic group and each BAG is an electron- accepting group of formula (II) --- is a bond to EDG; each R10 is, independently in each occurrence, H or a substituent; each R11-R14 is, independently in each occurrence, H or an electron- withdrawing group; and of the first and second compounds of formula (I), the total number of electron- withdrawing groups R11-R14 is greater for the first compound of formula (I). The composition may further contain an electron donor capable of donating an electron to the compounds of formula (I). The composition may be used in the photoactive layer of an organic photodetector.
(FR)
L'invention concerne une composition contenant un premier composé et un deuxième composé de formule (I), dans laquelle EDG est un groupe donneur d'électrons comprenant un groupe hétéroaromatique polycyclique et chaque BAG est un groupe accepteur d'électrons de formule (II), --- étant une liaison avec EDG ; chaque R10 représente, indépendamment à chaque occurrence, H ou un substituant ; chaque R11-R14 représente, indépendamment à chaque occurrence, H ou un groupe attracteur d'électrons ; et des premier et deuxième composés de formule (I), le nombre total de groupes attracteurs d'électrons R11-R14 étant supérieur pour le premier composé de formule (I). La composition selon l'invention peut également contenir un donneur d'électrons apte à donner un électron aux composés de formule (I). Cette composition peut être utilisée dans la couche photoactive d'un photodétecteur organique.
