摘要
Organic porous chiral thin films of tris(8-hydroxyquinoline) aluminum have been made (see Figure) using glancing-angle deposition (GLAD). The films emit circularly polarized light under photoexcitation and consist of highly uniform, self-organized arrays of submicrometer helices. These films combine the molecular diversity of organic chemicals with the complex submicrometer morphologies achievable by GLAD in a single-step process.
