This invention provides a highly fluorescent material containing a single (i=0) or a series of (i=1, 2, etc.) complex ring systems. This chromophore is particularly useful for the absorption and emission of photons in the visible light wavelength range and near-infrared wavelength range. This chromophore, highly luminescent with photostability, has various applications, such as in wavelength conversion films. Wavelength conversion films have the potential to significantly improve the concentration efficiency of solar light in photovoltaic devices or solar cells.
