The invention provides highly fluorescent materials comprising a heterocyclic systems represented by formula (I): D1-HetL-HetiD2, wherein i is 0 and Het is
wherein X is —S—. 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.
本发明提供了由式(I)代表的杂环系统组成的高荧光材料:D1-HetL-HetiD2,其中 i 为 0,Het 为
其中 X 为-S-。这些发色团特别适用于吸收和发射可见光和近红外波长范围内的光子。光稳定的高发光发色团可用于各种应用,包括波长转换薄膜。波长转换薄膜有可能显著提高光伏或太阳能电池装置的太阳能收集效率。
