本文描述了带有 1,8-萘二甲酰亚胺荧光吊坠的氢键分子双链体的设计、合成和表征。两条寡酰胺分子链，具有互补的氢键序列DDADAA和AADADD，可以形成超稳定的自组装双链体。通过1H NMR和ESI-MS确认了其分子结构，并测定了其光致发光性能。与相应的1,8-萘二甲酰亚胺链段（32.4％）相比，所得双链体的光致发光（PL）量子效率显着增强，达到63.7％，这表明较大分子量双链体的形成可以成功抑制荧光悬挂物的猝灭。这种新颖的双相体是新型电致发光发射器的潜在候选者。
This paper describes the design, synthesis and characterization of a hydrogen-bonded molecular duplex with 1,8-naphthalimide fluorescent pendants. The two oligoamide molecular strands, with complementary hydrogen bond sequences of DDADAA and AADADD, can form an ultra stable self-assembly duplex. Its molecular structure was confirmed by 1H NMR and ESI-MS, and its photoluminescence properties were determined. The resulting duplex exhibited a dramatically enhanced photoluminescence (PL) quantum efficiency of 63.7% compared to the corresponding 1,8-naphthalimide segment (32.4%), suggesting that the formation of the duplex with larger molecular weight could successfully inhibit the quenching of the fluorescent pendant. This novel duplex is a prospective candidate for new electroluminescent emitter.
