In connection with our previous research on μ-oxo-bridged metal phthalocyanine dimers, we have synthesized μ-oxo-bridged subphthalocyanine dimers (μ-oxo subpc dimers) with various peripheral substituents and studied their properties. Compared to the corresponding subpc monomer, the Q-band absorption of subpc dimers broadens, the wavelength undergoes a blue shift by approximately 30–35 nm, and the molar absorptivity is enhanced almost 1.5–2.0 times. Additionally, its solubility in various organic solvents is much improved. We carried out an X-ray crystal structure analysis of [B(subpc)}2O] and provided a direct observation of its asymmetric structure for the first time.
与我们之前对μ-氧桥接金属酞菁二聚体的研究相关,我们合成了具有多种外围取代基的μ-氧桥接亚酞菁二聚体(μ-氧亚酞菁二聚体)并研究了它们的性质。与相应的亚酞菁单体相比,亚酞菁二聚体的Q带吸收变宽,波长蓝移约30-35纳米,摩尔吸光度增强了近1.5-2.0倍。此外,它在各种有机溶剂中的溶解度有了显著提高。我们对[B(subpc)}2O]进行了X射线晶体结构分析,并首次直接观察到了其不对称结构。
