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 gap. Imaging with an InGaAs-based SWIR camera and various longpass filters confirmed detection >1300 nm.
