Abstract: PORPHYRINS HAVE BEEN EXTENSIVELY STUDIED OVER SEVERAL DECADES PRIMARILY DUE TO THEIR IMPORTANCE IN BIOLOGICAL SYSTEMS. MOREOVER, THEIR UNIQUE OPTICAL AND ELECTROCHEMICAL PROPERTIES AND THEIR HIGH CHEMICAL AND THERMAL STABILITIES MAKE THEM ATTRACTIVE MATERIALS IN ELECTRONICS, OPTOELECTRONICS AND PHOTONICS. RECENT RESEARCH IN OUR GROUP HAS DEMONSTRATED THAT CERTAIN TYPE OF POLYCYCLIC AROMATIC HYDROCARBONS COULD SHOW AN OPEN-SHELL DIRADICAL GROUND STATE. THIS NEW TYPE DIRADICALOIDS EXHIBITED VERY UNIQUE OPTICAL, ELECTRONIC AND MAGNETIC PROPERTIES AND HAVE POTENTIAL APPLICATIONS FOR ORGANIC ELECTRONICS, SPINTRONICS AND PHOTONICS. IT WOULD BE INTERESTING TO DESIGN AND SYNTHESIZE PORPHYRIN-BASED DIRADICALOIDS. SO FAR, ALTHOUGH VARIOUS LOW BAND GAP PORPHYRINOIDS SUCH AS AROMATIC-FUSED PORPHYRINS AND QUINOIDAL PORPHYRINS HAVE BEEN SYNTHESIZED, FEW OF THEM SHOWED AN OPEN-SHELL DIRADICAL CHARACTER IN THE GROUND STATE. IN THIS DISSERTATION, WE HAVE DESIGNED AND SYNTHESIZED A SERIES OF PORPHYRIN-B
