Abstract:
The invention provides highly fluorescent materials comprising a single (i=0) or a series (i=1, 2, etc.) of heterocyclic systems. The chromophores are particularly useful for absorption and emission of photons in the visible and near infrared wavelength range. The photo-stable highly luminescent chromophores are useful in various applications, including in wavelength conversion films. Wavelength conversion films have the potential to significantly enhance the solar harvesting efficiency of photovoltaic or solar cell devices.

Claim (Index 1):
A chromophore represented by formula I: wherein Het is selected from the group consisting of: wherein:\n i is 0 or an integer in the range of 1 to 100; \n X is selected from the group consisting of \u2014N(A 0 )-, \u2014O\u2014, \u2014S\u2014, \u2014Se\u2014, and \u2014Te\u2014; \n Z is selected from the group consisting of \u2014N(R a )\u2014, \u2014O\u2014, \u2014S\u2014, \u2014Se\u2014, and \u2014Te\u2014; \n A 0  is selected from the group consisting of hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted heteroalkyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted amino, optionally substituted amido, optionally substituted cyclic amido, optionally substituted cyclic imido, optionally substituted alkoxy, optionally substituted acyl, optionally substituted carboxy, and optionally substituted carbonyl; \n R a , R b , and R c , are independently selected from the group consisting of hydrogen, optionally substituted alkyl, optionally substituted alkoxyalkyl, optionally substituted alkenyl, optionally substituted heteroalkyl, optionally substituted heteroalkenyl, optionally substituted aryl, optionally substituted arylalkyl, optionally substituted heteroaryl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted cycloheteroalkyl, optionally substituted cycloheteroalkenyl, optionally substituted amino, optionally substituted amido, optionally substituted cyclic amido, optionally substituted cyclic imido, optionally substituted alkoxy, optionally substituted carboxy, and optionally substituted carbonyl; or R a  and R b , or R b  and R c , or R a  and R c , together form an optionally substituted ring or an optionally substituted polycyclic ring system, wherein each ring is independently cycloalkyl, aryl, heterocyclyl, or heteroaryl; \n D 1  and D 2  are independently selected from the group consisting of hydrogen, optionally substituted alkoxy, optionally substituted aryloxy, optionally substituted acyloxy, optionally substituted alkyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted amino, optionally substituted amido, optionally substituted cyclic amido, optionally substituted cyclic imido, -aryl-NR\u2032R\u2033, -aryl-aryl-NR\u2032R\u2033, and -heteroaryl-heteroaryl-R\u2032; wherein R\u2032 and R\u2033 are independently selected from the group consisting of optionally substituted alkyl, optionally substituted alkenyl, optionally substituted aryl; provided that D 1  and D 2  are not both hydrogen, and D 1  and D 2  are not optionally substituted thiophen or optionally substituted furan; and \n L is independently selected from the group consisting of optionally substituted alkyl, optionally substituted aryl, optionally substituted heteroaryl, amino, amido, imido, optionally substituted alkoxy, acyl, carboxy, provided that L is not optionally substituted thiophene or optionally substituted furan.
