Abstract
(EN)
A compound of formula (I): EAG – EDG – EAG (I) wherein EDG is an electron-donating group comprising a polycyclic heteroaromatic group and each EAG is an electron-accepting group of formula (II): (II) wherein R10 in each occurrence is H or a substituent; ---- is a bond to EDG; and each X1 -X4 is independently CR11 or N wherein R11 in each occurrence is H or a substituent, with the proviso that at least one occurrence of at least one of X1 -X4 is N. The compound may be used as an acceptor in a bulk heterojunction layer of an organic photodetector.
(FR)
La présente invention porte sur un composé de formule (I) : EAG – EDG – EAG (I), dans laquelle EDG est un groupe donneur d'électrons comprenant un groupe hétéroaromatique polycyclique et chaque EAG est un groupe accepteur d'électrons de formule (II) : (II) dans laquelle R10 dans chaque cas est H ou un substituant ; ---- est une liaison avec EDG ; et X1 et X4 sont indépendamment CR11 ou N, R11 dans chaque cas étant H ou un substituant, à condition qu'au moins une occurrence de X1 et/ou X4 soit N. Le composé peut servir d'accepteur dans une couche d'hétérojonction massive d'un photodétecteur organique.
