disulfonyl azides, and iminophosphorane is developed to construct N, O, S, and P-containing heteroatom-rich poly(phosphorus amidine)s with advanced functionalities. The optimized MCP proceeds at room temperature in THF under the catalysis of CuI, generating polymers with high molecular weights (up to 85 600 g/mol) in excellent yields (up to 92%). The MCP enjoys general applicability of various monomers including
多组分聚合(MCP)是一种引人入胜的合成方法,用于构建具有多种结构和多功能的聚合物。作为一个快速发展的领域,MCP开始对聚合物化学和聚合物材料产生巨大影响,以其便捷性和高效性,巨大的结构多样性,高原子经济性和环境效益吸引了科学家的注意力。在这项工作中,开发了一种易于实现的二炔,二磺酰基叠氮化物和亚氨基正膦的一锅三组分聚合反应,以构建具有先进功能的N,O,S和P含杂原子的聚磷phosph。优化的MCP在室温下于CuI的催化下在THF中进行,从而以高收率(最高92%)生成高分子量(最高85 600 g / mol)的聚合物。MCP具有包括芳香族和脂肪族炔在内的各种单体的普遍适用性,并且聚合反应产生的唯一副产物是氮气,这证明了高原子经济性和环境效益。有趣的是,发现磷am模型化合物既具有聚集诱导的发射行为,又具有热活化的延迟荧光,表明相应聚合物材料的独特特征。该聚合物通常在极性有机溶剂中具有良好的
