不同结构和聚合度的二维聚酞菁（PPC）：化学因素、表征和加工性能
2D polyphthalocyanines (PPCs) of different structure and polymerization degree: chemical factors, characterization and processability
摘要：
二维共轭聚酞菁可以作为两种具有特定分子结构和不同形态性质的明显不同类型的材料获得。温度是影响化学反应的关键因素，但我们发现，即使在最佳温度（420°C）下，气/固界面和液/固界面上的反应也会产生不同的产物：前者是高度聚合和有序的，而后者是无定形的，具有典型的单PC环共轭规模。红外光谱是鉴定分子结构的最灵敏的工具，提供了聚合度、结构均匀性和端基含量的信息。我们表明，与有序PPC不同，交联产物可以作为连续导电材料可重复地获得。
英文摘要：
2D conjugated polyphthalocyanines can be obtained as two distinctly different types of material with specific molecular structures and different morphological properties. It was believed that the temperature is the key factor affecting the chemical reaction, but we show that even at the optimal temperature (420°C), the reaction on vapor/solid interface and liquid/solid interface yields different products: while the former is well-polymerized and ordered, the latter is amorphous and cross-linked with the typical conjugation scale of single PC ring. IR spectroscopy is most sensitive tool for identifying the molecular structure, providing the information on polymerization degree, structural uniformity and content of terminal groups. We show that, unlike the ordered PPCs, the cross-linked product can be reproducibly obtained as continuous conductive material.
