Flavins are known to be extremely versatile, thus enabling routes to innumerable modifications in order to obtain desired properties. Thus, in the present paper, the group of bio-inspired conjugated materials based on the alloxazine core is synthetized using two efficient novel synthetic approaches providing relatively high reaction yields. The comprehensive characterization of the materials, in order to evaluate the properties and application potential, has shown that the modification of the initial alloxazine core with aromatic substituents allows fine tuning of the optical bandgap, position of electronic orbitals, absorption and emission properties. Interestingly, the compounds possess multichromophoric behavior, which is assumed to be the results of an intramolecular proton transfer.
黄素是众所周知的非常通用的，因此能够通过无数的修饰途径来获得所需的性质。因此，在本论文中，基于蝶啶核心的生物启发共轭材料组使用两种有效的新型合成方法合成，提供了相对较高的反应产率。为了评估材料的性质和应用潜力，对材料进行了全面的表征，结果表明，用芳香取代基修饰初始蝶啶核心可以精细调节光学带隙、电子轨道位置、吸收和发射性质。有趣的是，这些化合物具有多色团行为，这被认为是分子内质子转移的结果。
