Development of controlled reactions using an element-based design of azaporphyrinoid materials

Abstract

Phthalocyanines (Pcs) and related macrocycles (azaporphyrinoids) are well-known artificial dyes in modern material chemistry. Several strategies for fine-tuning their optical/electrochemical/aromatic properties have been proposed. The diversity of Pcs enables novel functionalities that can assist in innovative approaches to tune and improve the properties of diverse material. Organic synthesis yields a wide array of organic molecules. Herein, the author describes two methods for developing controlled reactions in organic synthesis: controlled reactions to produce novel Pcs and controlled reactions using Pcs. In particular, the author proposes an “element-based” design strategy to obtain unique properties using a simple synthetic procedure. This strategy permits the fine-tuning of optical properties in the near-infrared (NIR) region (700–1000 nm). These innovations should create further opportunities for flexible applications of NIR light
