Abstract
The invention provides highly fluorescent materials comprising a single (n=0) or a series (n=1, 2, etc.) of benzo heterocyclic systems. 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.
