Abstract Stimuli responsive π-conjugated macrocyclic systems has shown significant attention in organic electronics, however, amongst them, porphyrins and phthalocyanines unveiled remarkable growth towards materials and biological applications. Herein, we report bulk electrolysis of Zn-phthalocyanine system (ZnPc-OMe) under potential difference of 1.5 V in chloroform results anion binding mechanism directs the formation of self-assembled nanospheres by diffusion controlled approach. Electrochemical and UV–Vis absorption studies of ZnPc-OMe suggest that anion (Cl−) binding ability towards ‘Zn‘ whilst applied potential leads to the formation of H+[(Cl)ZnPc-OMe]- promote the enhanced current and charge generation. Microscopic analysis revealed that ZnPc-OMe and H+[(Cl)ZnPc-OMe]- exhibit the nanosheets and spheres with an average diameter of 0.5–1 μm and 300–500 nm, respectively. Powder X-ray diffraction analysis and raman spectra revealed the changes in crystalline phase transitions via ion-dipole and π-π stacking interactions. Thus, these unique features are atypical for phthalocyanine derivative hitherto unknown.

锌-酞菁的本体电解揭示了通过阴离子结合的自组装纳米球

摘要 刺激响应 π 共轭大环系统在有机电子学中表现出极大的关注，然而，其中，卟啉和酞菁在材料和生物应用方面取得了显着的增长。在此，我们报告了氯仿中 1.5 V 电位差下 Zn-酞菁系统 (ZnPc-OMe) 的本体电解结果，阴离子结合机制通过扩散控制方法指导自组装纳米球的形成。ZnPc-OMe 的电化学和 UV-Vis 吸收研究表明，阴离子 (Cl-) 对“Zn”的结合能力同时施加的电位导致 H+[(Cl)ZnPc-OMe]- 的形成，促进增强的电流和电荷产生。显微分析表明，ZnPc-OMe 和 H+[(Cl)ZnPc-OMe]- 呈现出平均直径为 0 的纳米片和球体。分别为 5–1 μm 和 300–500 nm。粉末 X 射线衍射分析和拉曼光谱揭示了通过离子-偶极子和 π-π 堆积相互作用的结晶相变变化。因此，这些独特的特征对于迄今为止未知的酞菁衍生物来说是非典型的。
