differences between the behavior of the furan‐ and the thiophene‐based auxochromes. Four regioisomeric bis‐thienylchlorins (3,10; 3,13, 3,15 and 10,15) were oxidatively electropolymerized; the chlorin monomer geometry had a profound impact on the polymerization efficiency and the electrochemical properties of the resulting material.

从头与五元杂环化学稳定的二氢卟酚(呋喃,噻吩,和formylfurane醛基)中选择的取代基的合成内消旋-和β-位置报告。在3-和13-位的杂环掺入移位二氢卟酚的吸收和发射红色(高达λ EM= 680nm),因此这些容易结合的取代基的功能类似于叶绿素中存在的辅助色素,例如甲酰基和乙烯基。光物理,理论和X射线晶体学实验表明,呋喃基和噻吩基辅助色素的行为之间存在细微但显着的差异。四个区域异构的双噻吩基二氢卟酚(3,10; 3,13,3,15和10,15)被氧化电聚合。二氢卟酚单体的几何形状对所得材料的聚合效率和电化学性能产生了深远的影响。3,13-双噻吩二氢与3-己基噻吩的化学共聚产生了有机可溶的发红光聚合物。
