A study on the synthesis of derivatives of 4,5-bis(dimethylamino)quinoline, which is a quinoline analog of 1,8-bis(dimethylamino)naphthalene (also known by its trade name Proton Sponge) was carried out. The first two representatives of this series were obtained. Depending on the aggregate state, solvent, and structural features, these compounds may be protonated either at the quinoline heteroatom or peri-NMe2 groups.

synthesised from olefinic precursors via a photochemical isomerisation-cyclisation route, and incorporated into octadentate cyclen triacetate ligands that formed luminescent complexes with Tb(III) and Eu(III). The photophysical properties of the emitters were strongly dependent on the position of the fluorination.
在 3、5 或 6 位单氟化的喹诺酮类化合物由烯烃前体通过光化学异构化-环化途径合成,并结合到与 Tb( III ) 和 Eu( III )形成发光络合物的八齿环烯三乙酸酯配体中。发射器的光物理性质强烈依赖于氟化的位置。
