Abstract : The synthesis, spectral characterization, and electrochemical behavior of bis(tri-n-hexylsiloxy)-2,3-phthalocyaninatosilicon (SiPc(OR)2), its dimer (RO(SiPcO)2R), and its naphthalocyanine analog (SiNc(OR)2) are described. All compounds show near UV absorption corresponding to Soret and N bands and intense absorption in the visible-near IR region corresponding to Q-bands. In CH2Cl2, within the solvent stability limit, there are two reductions and one oxidation for SiPc(OR)2 and two reductions and two oxidations for RO(SiPcO)2R and SiNc(OR)2; all appear as reversible one electron waves, although n=2 for the dimer. The difference in the peak potentials of the first oxidation and first reduction waves agrees well with the excitation energy and fluorescence (corresponding to Q-bands) of SiPc(OR)2 and SiNc(OR)2.

硅酞菁和硅萘酞菁：合成、电化学和电致化学发光

摘要 : 双(三正己基甲硅烷氧基)-2,3-酞菁硅(SiPc(OR)2)、其二聚体(RO(SiPcO)2R)及其萘酞菁类似物(SiNc)的合成、光谱表征和电化学行为(OR)2) 进行了描述。所有化合物均表现出对应于 Soret 和 N 波段的近紫外吸收，以及对应于 Q 波段的可见-近红外区域的强烈吸收。在CH2Cl2中，在溶剂稳定性限度内，SiPc(OR)2有2次还原和1次氧化，RO(SiPcO)2R和SiNc(OR)2有2次还原和2次氧化；尽管二聚体的 n=2，但都表现为可逆的单电子波。第一次氧化波和第一次还原波的峰值电位差与 SiPc(OR)2 和 SiNc(OR)2 的激发能量和荧光（对应于 Q 带）非常吻合。
