以合成四苯基卟啉的经典反应为模板,通过分子设计,在理论计算的指导下,将原料中的苯甲醛替换为具有双齿结构的对苯二甲醛,从而实现在卟啉单体形成的过程中,一步合成共价桥连的对苯二甲醛代替苯甲醛与吡咯反应,成功合成了中位-苯基桥连二维苯基聚卟啉薄膜,薄膜的厚度为1～3nm,具有高定向度、扩展共轭、可独立存在的特点。
Based on the classic synthesis of tetraphenylporphyrin,an an efficient method was designed to build planar porphyrin films by using terephthalaldehyde contributed reaction with theoretical calculations.As a result,the polyporphyrin atomical thin films were successfully synthesized by real-time covalently bridging porphyrin during their monomer synthesis.The planar units exhibited high orientation in two-dimensional construction,leading to the formation of atomical thin films with thickness of 1～3nm.
