Spectroscopic Investigations on Polymeric Tetra Benzo 18-Crown-6 Ether Bridged Metal-Free Phthalocyanine

Abstract

Phthalocyanines, crown ethers, and crown ether bridged phthalocyanine compounds have recently attracted a great deal of attention because of their interesting properties^1–5. The spectroscopic specifications of these molecules have been studied for a long time. However, their structures are not completely elucidated since they have relatively big monomers, and form giant polymers^4,6,7. There are many studies on the spectroscopic specifications of phthalocyanines^8–10, but one of them which recently appeared in Journal of Chemical Physics may be important as a theoretical reference from now on¹. Similarly, the spectroscopic properties of crown ethers have been investigated for about twenty years^11,12. Meanwhile, some spectroscopic properties of crown ether bridged phthalocyanine compounds have also investigated previously^3–7,13,14
