1：Experimental Design and Method Selection:

The study involved synthesizing nine new tetrasubstituted metallophthalocyanines using microwave irradiation for cyclotetramerization, followed by characterization using various spectroscopic and analytical techniques. DFT calculations were employed for theoretical support.

2：Sample Selection and Data Sources:

Compounds were synthesized from precursors like 1,2-dicyan-4,5-dichlorobenzene and specific dithiones, with metal salts (CoCl2·6H2O, NiCl2, CuCl2·2H2O).

3：List of Experimental Equipment and Materials:

Equipment included a CEM Discover microwave apparatus, Hitachi U-2000 and Varian Cary 3E UV-Vis spectrophotometers, Shimadzu IR Affinity-1 spectrometer, Pine Bipotentiostat AFCBP1, Varian 300 Unity Plus NMR spectrometer, Shimadzu RF-5301PC spectrofluorophotometer, Mettler/Toledo TGA/DSC1 Stare System, ICP-MS THERMO ICAP-Qc spectrometer, and Bruker UltrafleXtreme MALDI-TOF/TOF spectrometer. Materials were purchased from Sigma-Aldrich.

4：Experimental Procedures and Operational Workflow:

Synthesis involved nucleophilic displacement and microwave-assisted cyclotetramerization in DMAE solvent under argon. Purification was done via column chromatography or Soxhlet extraction. Characterization included UV-Vis, IR, NMR, fluorescence, CV, TGA, MS, and elemental analysis.

5：Data Analysis Methods:

Data were analyzed using standard spectroscopic and electrochemical techniques, with DFT calculations performed using Gaussian 09 with B3LYP functional and SVP basis set.
