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.

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.

Secondary and tertiary amines 6 are conveniently prepared in good yields by reacting organozinc halides with adducts 4, which are derived from the corresponding amines, aldehydes and benzotriazole. The use of organozinc reagents enables the introduction of nitro, cyano or ester functionalities into amine mainframes. This methodology was also used to prepare functionalized amides 8.
