Paper Abstract

The synthesis and photosensing ability of a novel green-absorbing dendrimer are presented. The photoresponse of a photodiode comprising a bulk heterojunction blend of a first generation ketocyanine-cored dendrimer with carbazole dendrons and fluorenyl surface groups and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) shows good spectral selectivity for digital camera applications. The narrow absorbing photodiode achieved an external quantum efficiency of 2.9% at 515 nm and maintained a profile similar to the absorption of the unblended dendrimer.
