  A new type of materials, organic salts in the crystal state, have ultralong organic phosphorescence (UOP) under ambient conditions. The change of cations (NH4+, Na+, or K+) in these phosphors gives access to tunable UOP colors ranging from sky blue to yellow green, along with ultralong emission lifetimes of over 504 ms. Single‐crystal analysis reveals that unique ionic bonding can promote an ordered

  一种新型材料，晶体状态的有机盐，在环境条件下具有超长有机磷光（UOP）。阳离子（NH 4 +，Na +或K +）中的这些磷光体可以访问从天蓝色到黄绿色的可调UOP颜色，以及超过504 ms的超长发射寿命。单晶分析表明，独特的离子键合可以促进晶体态有机盐的有序排列，然后可以促进UOP生成的分子聚集。此外，可通过交替使用发烟气体（氨气和氯化氢）来实现可逆的超长磷光，这证明了其作为可视氨气或氯化氢气体感测候选物的潜力。结果为扩大超长有机磷光材料的范围及其应用提供了一种对环境负责的可行的合成方法。

  Polyether amides are produced by reacting at least one polyalkylene glycol diamine with at least two dicarboxylic acids or esters thereof. The polyethylene glycol diamine has the formula NH₂-(CH₂CH₂O)x-CH₂CH₂-NH₂, where x ranges from 2 to 6, and at least one of the dicarboxylic acids is an aromatic dicarboxylic acid. The polyether amides may have the formula: where each R and R' are independently an alkyl or aryl moiety having from 3 to 34 carbon atoms, where at least one R or R' is an aryl moiety, and where each x and y independently have the values noted. The resulting polyether amides are useful to make polymers, including fibers, with unusually good water absorbancy properties.
