Abstract:
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.

Claim (Index 1):
A chromophore represented by formula (III): wherein Pen is wherein: A 1  is optionally substituted alkyl, optionally substituted alkenyl, optionally substituted heteroalkyl, or optionally substituted carbonyl; X 1  is CR 1  or N, X 2  is CR 2  or N, X 3  is CR 3  or N, X 4  is CR 4  or N; Z is S, O, CR 1 , or NR 5 ; Y is C or N; R 1 -R 4  are each independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted heteroalkyl, optionally substituted amido, optionally substituted alkoxy, optionally substituted carbonyl, and optionally substituted carboxy, optionally substituted aryloxy, optionally substituted acyloxy, optionally substituted ketone, optionally substituted ester, optionally substituted ether, \u2014F, \u2014CN, \u2014CF 3 , \u2014NO 2 , or \u2014Br; R 5  is hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted heteroalkyl, optionally substituted carbonyl, optionally substituted ketone, \u2014F, \u2014CN, \u2014CF 3 , \u2014NO 2 , or \u2014Br.
