Subphthalocyanine (SubPc) derivatives with different kind of substitute groups were synthesized successfully from various precursors using conventional and microwave heating sources. The chemical structure of precursor and product was determined by $^{1}H-NMR$ and FT-IR spectrometer. Also, spectroscopic property was measured by UV-Vis spectrometer. Compared to the conventional synthesis, it was found that SubPc derivatives were synthesized for a shorter reaction time with a higher synthetic yield in the microwave synthesis.

Subphthalocyanine (SubPc) derivatives consisting of the different kinds and positions of substitute group were successfully synthesized using various types of the precursor as the intermediate compound. The chemical structure of precursor and product was determined by the means of $^{1}H-NMR$ and FT-IR spectrometer. Also, spectroscopic and crystalline properties were determined by means of UV-Vis spectrometer and XRD, respectively. It was found that SubPc derivatives absorbed selectively visible light ranging from 560 to 600 nm, their solubility was enhanced by introducing substitute groups, and their maximum absorbing wavelength was shifted by changing the kind and position of substitute groups.

Phthalocyanine (Pc), porphyrin, subphthalocyanine, and perylene compounds can be applicable to the fields of optical storage media, organic solar cell, LCD, PDP, semiconductor, and counterfeit money detection etc. In this study, phthalocyanine hybrid derivatives were synthesized by cross-linking perylene, subphthalocyanine, or porphyrin to the main frame of Pc. Absorbtion band of two different wavelengths appeared simultaneously in the phthalocyanine hybrid derivatives. Compared to phthalocyanine, the solubility was enhanced and the degree of Q-band shift was changed according to the kind of substitute compounds. The chemical and optical properties of samples were analyzed using FT-IR, $^1H-NMR$, and UV-Vis spectroscopic techniques.
