  Rigid-Core Fluorescent Oligothiophene-S,S-dioxide Isothiocyanates. Synthesis, Optical Characterization, and Conjugation to Monoclonal Antibodies

  摘要：

  In this paper we report the synthesis of a new class of fluorescent thiophene-based isothiocyanates containing a 3,5-disubstituted dithieno[3,2-b:2',3'-d]thiophene-4,4-dioxide moiety as the rigid core, using the palladium-catalyzed cross-coupling reaction of aryl stannanes with aryl bromides (Stille coupling). By changing the molecular structure through the progressive addition of thienylene or phenylene units, light emission from blue to orange was obtained. Photoluminescence quantum yields ranged from 0.65 to 0.90 for blue and green light emitters to 0.10-0.35 for yellow and orange ones. Optically and chemically stable fluorescent bioconjugates were prepared by spontaneous reaction of the isothiocyanates with monoclonal antibodies anti-CD3 and anti-CD8 in slightly basic solutions.

  We report herein a redox-divergent construction of dihydrothiophenes, thiophenes, and bromothiophenes from readily available allylic alcohols, dimethyl sulfoxide (DMSO), and HBr, respectively. This strategy can serve for the programmable and concise synthesis of bioactive and functional molecules.

  我们在此报告了二氢噻吩、噻吩和溴噻吩的氧化还原发散结构，它们分别来自容易获得的烯丙醇、二甲基亚砜 (DMSO) 和 HBr。该策略可用于生物活性和功能分子的可编程和简洁合成。
