Abstract
This disclosure is related to photo-stable chromophores which are useful in various applications. Chromophores disclosed herein include a bis-triazole core, two electron-donors at C-4 and C-8, and two groups derived from pentaerythritol (R═OR5) or 1,1,1-tris(hydroxymethyl)methane (R═H) at N-2 and N-6. Such structures have been proven to have greater then five times higher photo-stability than their analogs with simpler alkyl groups at N-2 and N-6.
