(EN) PHOTOACTIVE COMPOUND
(FR) COMPOSÉ PHOTOACTIF
Abstract
(EN)
A compound of formula (I): Each R1 and R2 is, independently in each occurrence, a substituent. Each R3 -R10 is, independently in each occurrence, H or a substituent. At least one occurrence of at least one of R11-R14 is CN. Each Y is independently O or S. Z1-Z4 are each independently a direct bond or Z1, Z2, Z3 and / or Z4 together with, respectively, R4 or R5, R7 or R8, R6, or R9 forms an aromatic or heteroaromatic group. The compound of formula (I) may be provided in an active layer of an organic electronic device, e.g. as an electron acceptor in a bulk heterojunction layer of an organic photodetector. A photosensor may comprise the organic photodetector and a light source, e.g. a near infra-red light source.

Un composé de formule (I) : Chaque R1 et R2 est, indépendamment à chaque occurrence, un substituant. Chaque R3 -R10 est, indépendamment à chaque occurrence, H ou un substituant. Au moins une occurrence d'au moins un élément parmi R11-R14 est CN. Chaque Y est indépendamment O ou S. Z1-Z4 sont chacun indépendamment une liaison directe ou Z1, Z2, Z3 et/ou Z4 conjointement avec, respectivement, R4 ou R5, R7 ou R8, R6, ou R9 forment un groupe aromatique ou hétéroaromatique. Le composé de formule (I) peut être disposé dans une couche active d'un dispositif électronique organique, par exemple en tant qu'accepteur d'électrons dans une couche d'hétérojonction massive d'un photodétecteur organique. Un photocapteur peut comprendre le photodétecteur organique et une source de lumière, par exemple une source de lumière proche infrarouge.
