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═OR
5
) 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.

Described herein are novel azo-benzene type chromophores. The chromophores are useful in photochromic compositions comprising a polymer matrix and a chromophore, wherein the chromophore is a novel azo-benzene type structure. The photochromic composition is photoresponsive upon irradiation by at least one wavelength of laser light across the visible light spectrum. Photochromic devices which comprise the novel azo-benzene type chromophore compound show significantly higher photoinduced birefringence, higher diffraction efficiency, and brighter images than devices that comprise well known azo-benzene chromophores. The photochromic composition may include a liquid crystal.
