Abstract
Provided herein are transmitter ligands that improve photon upconversion of near infrared light (NIR) to visible light. The presently provided ligands are complexed to semiconductor nanocrystals and improve triplet energy transfer from semiconductor nanocrystal to annihilator in triplet-triplet annihilation. Suitable applications include bio-imaging.
