镍（II）5，15-二苯基卟啉和镍（II）5，15-双（二-3，5-叔丁基苯基）卟啉通过氧化化学气相沉积（oCVD）的氧化聚合产生薄膜形式的多稠合卟啉低聚物。oCVD技术能够一步形成、沉积和p掺杂共轭聚（卟啉）涂层，而无需溶剂或后处理。通过高分辨率质谱分析显示了oCVD过程中的决定性反应和副反应。由于熔融带的高度共轭结构，薄膜表现出3.6 × 10（-2）Scm（-1）的电导率和在可见光至近红外光谱区的强吸收。光滑的共轭聚（卟啉）涂层的形成，即使在敏感的基板上，是通过在玻璃，硅和纸上的沉积和图案化来证明的。导电聚（卟啉）薄膜的形成可以使新的光电器件的设计使用的CVD方法。
Oxidative polymerization of nickel(II) 5,15-diphenyl porphyrin and nickel(II) 5,15-bis(di-3,5-tert-butylphenyl) porphyrin by oxidative chemical vapor deposition (oCVD) yields multiply fused porphyrin oligomers in thin film form. The oCVD technique enables one-step formation, deposition, and p-doping of conjugated poly(porphyrins) coatings without solvents or post-treatments. The decisive reactions and side reactions during the oCVD process are shown by high-resolution mass spectrometry. Owing to the highly conjugated structure of the fused tapes, the thin films exhibit an electrical conductivity of 3.6x10(-2)Scm(-1) and strong absorption in the visible to near-infrared spectral region. The formation of smooth conjugated poly(porphyrins) coatings, even on sensitive substrates, is demonstrated by deposition and patterning on glass, silicon, and paper. Formation of conductive poly(porphyrins) thin films could enable the design of new optoelectronic devices using the oCVD approach.
