纤维状的H-聚集体的长度可达300 μ m的合成通过自组装的硫菁（TC）染料分子在溶液中。光致发光（PL）的图像和空间分辨的PL光谱的光纤被转移到玻璃基板上显示，光纤作为单模光波导传播PL在520至560 μ m的范围内超过250 μ m没有任何损失。
Fiber-shaped H-aggregates with lengths of up to 300 mu m are synthesized by self-assembly of thiacyanine (TC) dye molecules in solution. Photoluminescence (PL) images and spatially resolved PL spectra of the fibers that are transferred onto a glass substrate reveal that the fibers act as single-mode optical waveguides that propagate PL in the range of 520 to 560 mu m over 250 urn without any loss.
