A novel porous organic polymer(POP)has been constructed through the condensation of triptycene tricatechol and 1,3,5-benzenetris(4-phenylboronic acid).This triptycene-based POP exhibited high H2 uptake(up to 1.84 wt%at 77 K,1 bar),large CO_(2) adsorption capacity(up to 18.1 wt%at 273K,1 bar),and excellent CO_(2)/N_(2) adsorption selectivity(up to 120/1).The influence of solvent on the gas adsorption performance of the POP has also been investigated.

利用含蒽荧光配体9,10-双[(E)-2-(吡啶-4-基)乙烯基]蒽(BP4VA)分别与2种不同长度的二羧酸配体反应,合成了层柱型的金属有机框架(MOFs)材料FDM-26和具有dia拓扑的三维材料FDM-27,并解析了其单晶结构.此外,对含有配位键断裂缺陷的基于BP4VA配体的层柱型MOFs材料FDM-22晶体施加外界压力,研究了压力刺激对FDM-22结构和荧光性质的影响.结果表明,在压力作用下,FDM-22能够保持结构稳定,但其荧光发射波长出现红移.经分析发现,此压致变色性能是由于结构内压力诱导生成的配位缺陷数目增加所致.

先秦诸子围绕“礼乐”展开了激烈的辩论,儒家肯定“礼乐”,墨、道、法三家则否定“礼乐”。孔孟提倡“礼乐”,实质是想恢复“周礼”,实施仁政。荀子借鉴了道家“天乐”美学思想,吕不韦吸收了阴阳五行说,强调了音乐“审音知政”功能。墨子从功利的角度“非乐”,老子从愚民的立场否定“礼乐”,商鞅、韩非子为推行法治否定“礼乐”,均是为了维护统治阶级利益。庄子则从养生的角度否定“礼乐”。正反双方音乐美学思想虽有较大差异,各方内部代表人物的音乐美学思想也有不同,但重视音乐的政治伦理属性和审美属性却是一致的。通过争论与碰撞,先秦诸子们共同推进了音乐的这两大属性。
