Stimuli-responsive macrocycles are of importance for synthetic chemistry and smart materials. In this manuscript, we report two novel organoborane cyclophanes, which were successfully synthesized by ruthenium-catalyzed olefin metathesis. They are composed of one/two boron-doped helicene π-skeletons and flexible alkyl chain linkers, thus representing a new kind of non-conjugated organoborane macrocycles. Their cyclic structures and photophysical properties, as well as Lewis acidity were theoretically and experimentally investigated. Notably, two enantiomers in one single crystal are observed for one organoborane cyclophane, owning to the presence of helical π-framework in its cyclic structure. Moreover, their Lewis acid-base adducts may dissociate in the excited state and thus display intriguing photo-responsive fluorescence properties, which can be further modulated by temperature. This study thus provides a novel design strategy for non-conjugated organoborane macrocycles, which may promote the development of stimuli-responsive macrocyclic materials with fascinating properties.

背景SAPHO综合征是一种罕见的影响骨关节和皮肤组织的慢性炎症性疾病,该病病因及发病机制不明,临床表现多样,目前尚无特异性的诊断指标及统一的治疗策略。目的分析19例SAPHO综合征患者的临床特征,以提高临床医生对该病的认识。方法回顾性分析2013年10月至2021年12月在中国中医科学院西苑医院风湿科门诊就诊的19例SAPHO综合征患者的临床特征,分析患者的首发症状特点、骨关节及皮肤受累特点、实验室及影像学检查、合并症及手术史、用药及随访情况、误诊情况。结果19例患者中女17例,男2例;平均年龄为(43±12)岁,中位病程为1年。首发症状均为骨关节疼痛或皮肤病表现,以骨关节疼痛为首发症状的患者14例,以皮肤病为首发症状5例;骨关节及皮肤均受累患者16例(84.2%),仅骨关节受累、无皮肤受累的患者3例(15.8%)。骨关节受累最常见的部位是前胸壁,其次是脊柱、外周关节、骶髂关节。皮肤受累最常见的表现是掌跖脓疱疮(16例,84.2%),其中2例伴下肢银屑病样皮损,7例伴双手指甲损坏。18例行全身骨扫描检查,平均骨关节受累位点数为(3±1)个。10例(52.6%)患者曾经历误诊,平均延迟诊断时间为(3±5)年。6例(31.6%)合并扁桃体炎的患者中,均存在掌跖脓疱疮,3例患者行扁桃体切除术,2例术后症状好转、1年内无复发。结论SAPHO综合征是一种主要累及骨关节及皮肤的罕见病,临床误诊率较高,对该病常见受累部位的认识及全身骨显像等影像学检查有助于明确诊断,扁桃体炎可能与该病的发生、发展有一定关系。

燃烧数值模拟有助于认识诸如点火、火焰传播、火焰不稳定、熄火、湍流与火焰相互作用等基础燃烧过程、揭示其中的燃烧机理,是开发新型替代燃料和高性能燃烧器的重要研究手段.然而,燃烧过程涉及的广泛时空尺度和复杂物理化学过程给其数值模拟带来了巨大挑战.为了实现燃烧过程的高效精确数值模拟,必须解决复杂化学反应机理导致刚性问题和数值求解方程过多的问题.本文介绍了复杂化学反应机理处理方法的研究进展、化学反应机理简化方法和自适应化学反应机理(针对复杂化学反应机理导致数值求解方程过多的问题)、几种常用的高效积分算法和降维/重构方法(针对复杂化学反应机理导致常微分方程组刚性问题).为了有效地模拟多尺度燃烧过程,接下来需要进一步发展和综合应用自适应网格技术、高效积分算法与自适应时间步长技术、化学反应机理简化与自适应化学反应机理技术、以及自适应物理/化学模型技术.
