Abstract

We have investigated the development of erbium(III)-cored supramolecular complexes containing metalloporphyrins to circumvent the solubility problem and improve the optical amplification property. The new synthetic methodology was accomplished through the ligand-exchange model reaction using ErCl3 to optimize its synthetic condition We have designed and synthesized the model complexes to investigate coordination property between the ligand and the erbium ion. Highly coordinated erbium(III)-cored model complexes (at least 8 to 10 coordination) showed the strong near infrared(IR) emission at 1520 nm, corresponding to the 4I13/2 → 4I15/2 transition. Also, with these synthetic results, erbium(III)-cored supramolecular complexes based on metalloporphyrins were synthesized and characterized. They also showed the infrared emission of the 4I13/2 → 4I15/2 transition at 1520 nm.
