Title
(EN) ORGANIC PHOTODETECTOR
(FR) PHOTODÉTECTEUR ORGANIQUE
Abstract
(EN)
An organic photodetector comprising a photosensitive organic layer comprising an electron donor and an electron acceptor wherein the electron acceptor is a compound of formula (I): EAG – EDG – EAG (I) wherein each EAG is an electron accepting group; and EDG is an electron-donating group of formula (II) or (III): (II) (III) A photosensor may comprise the organic photodetector and a light source, e.g. a near infra-red light source.
(FR)
L'invention concerne un photodétecteur organique comprenant une couche organique photosensible comprenant un donneur d'électrons et un accepteur d'électrons, l'accepteur d'électrons étant un composé de formule (I) : EAG-EDG-EAG (I) chaque EAG étant un groupe accepteur d'électrons ; et EDG étant un groupe donneur d'électrons de formule (II) ou (III) : (II) (III) un photocapteur peut comprendre le photodétecteur organique et une source de lumière, par exemple une source de lumière du proche infrarouge.
