合成了Tröger的碱衍生物rac-TBPP，通过手性柱层析将其分离为两个对映体R2N-TBPP和S2N-TBPP。这些化合物显示出强圆偏振发光，胶值分别为+0.0021和- 0.0025。第二种制备基于rac-TBPP的cpl活性材料的方法是通过共组装策略将荧光rac-TBPP与手性酰谷氨酸凝胶DGG共凝胶。当racc - tbpp /DGG的摩尔比为1:80时，共凝胶的胶值比R2N-TBPP和S2N-TBPP对映体的胶值高约3倍。有趣的是，通过改变它们的化学计量比，可以有效地调节rac-TBPP/DGG共凝胶的CPL旋向性。
The Tröger's base derivative rac-TBPP was synthesized and separated into two enantiomers R2N-TBPP and S2N-TBPP by chiral column chromatography. These compounds show a strong circularly polarized luminescence with glum values of +0.0021, and −0.0025, respectively. The second way to fabricate the rac-TBPP-based CPL-active material is to co-gel the fluorescent rac-TBPP with a chiral ᴅ-glutamic acid gelator DGG by co-assembly strategy. At the molar ratio of rac-TBPP/DGG = 1:80, the glum value of the co-gel was about three times higher than the glum values of R2N-TBPP and S2N-TBPP enantiomers. Interestingly, the CPL handedness of the rac-TBPP/DGG co-gel could be adjusted effectively by changing their stoichiometric ratios.
