Abstract
3,6-dimethylamino fluorenone was functionalized with substituents to achieve an absorption maximum at 1012 nm and emission > 1300 nm. TD-DFT calculations confirmed that the substituent orbitals contribute to narrowing the HOMO-LUMO energy. Imaging with an InGaAs-based SWIR camera and various longpass filters confirmed detection > 1300 nm.
