Abstract
|
This research project focused on 3 primary areas of investigation. The generalized concept of low power photon upconversion has been developed under the auspices of this funding and has led to broad recognition that this technology, based on regenerative photochemical reactions, can be applied in a range of energy-relevant applications for the conversion of low energy sunlight to higher energy photons. A second focus related to developing systematically-variable photophysics in platinum acetylides, excited-state absorption in particular, for potential applications in optical limiting molecules has resulted in the synthesis and characterization of many new classes of chromophores in addition to theory capable of predicting excited state absorption spectra of select molecules. Finally, new classes of Ru(II) and Os(II) dyes have been developed and tested in operational dye-sensitized solar cells and the record efficiency for an Os(II)-based cell has been achieved as a result of AFOSR support.
