相变材料具有高的相变潜热和良好的形状稳定性，在热能工程和管理中受到广泛关注。本文以1，3，5-三甲酰基苯和副玫瑰苯胺为原料，通过Schiff碱偶联反应合成了高比表面积的富氮多孔有机聚合物（N-POP），该聚合物可取代85wt%的十八醇（ODA）作为PCM。所得ODA@ N-POP具有高达182.7 J/g的熔化潜热，满足形状稳定性，并且在100次加热循环时具有良好的可逆性，这对于太阳能热工程和管理是有希望的。
The development of phase change material (PCM) composites with high latent heat of fusion and good shape-stability have received considerable attention for thermal energy engineering and management. In this work nitrogen-rich porous organic polymers (N-POPs) with high surface areas synthesized via Schiff-base coupling between 1,3,5-triformylbenzene and pararosaniline base are presented, which can take up 85 wt % of 1-octadecanol (ODA) as a PCM. The resulting ODA@N-POPs exhibit a high latent heat of fusion up to 182.7 J/g, satisfying shape-stability, and good reversibility upon 100 heating cycles, which are promising for solar thermal energy engineering and management.
