are as defined herein. Compounds containing a moiety of Formula I are useful in a wide variety of applications including, but not limited to, as photocatalysts, use in OLEDs, in electronic components, etc. As an organic-based photocatalysts, compounds containing a moiety of Formula I are activated by a relatively low energy electromagnetic wavelength, e.g., wavelength of 600 nm or greater. Furthermore, compounds of the invention can be used as both photoreduction catalysts and photooxidation catalysts.
