Supramolecular polymers with different functionalities have been continuously developed in the past decade because of their indispensable role in soft materials.However,pure organic supramolecular polymers with stable room temperature phosphor-escence (RTP) emission were very rarely reported for the difficulties of synthesis and achieving RTP in solution.Herein,soluble helical supramolecular polymers with circularly polarized room-temperature phosphorescence were developed via a facile host-guest strategy.Through assembly,a transition from pure fluorescence to almost pure RTP emission was achieved.Adjusting the asymmetry of guest could easily control the chiroptical property of supramolecular polymers.This work provides new op-portunities for the design and development of intelligent soft functional soft materials.

项目模式和标准问题是我国企业参与“一带一路”项目建设必须面对的重要问题.标准“走出去”对深入实施“一带一路”具有重要意义,而标准“走出去”需要以一体化项目模式为载体.从深入实施“一带一路”倡议的实际需要出发,分析不同条件下企业可选择的一体化项目模式及采用中国标准的可行性,企业实施一体化项目模式必须充分认识其内涵和风险并具备实施一体化项目的 能力.在分析中国标准在“一带一路”项目中的应用现状的基础上,对如何推动中国标准国际化提出了对策建议.
