Synthesis and Evaluation of Various Photoluminescent Materials via New Organometallic Chemistry Routes

Introduction

Organic molecules and macromoleculers with extended conjugated π-electron systems exhibit intriguing electronic and optical properties, and they are expected to serve as next-generation functional materials for organic film solar cells, organic transistors, organic electro-luminescence (OEL) devices, etc. In particular, the materials utilizing the photoluminescent properties are applicable not only to OEL but also many fields, such as chemical sensors, PL imaging probes, etc. Since the photoluminescence properties, i.e. colors and intensities, depend on the chemical structure of the materials, synthetic methods that enable versatile molecular designs of this class of materials are significantly important. This article introduces synthetic methods for "heteroatom-containing unprecedented π-conjugated polymers" and "high efficiency aggregation-induced emission (AIE) dyes" we reported recently, as well as the successful results obtained by the evaluation of their optical features using an UV-vis spectrophotometer (UV-3100) and spectrofluorophotometers (RF-5300 or RF-6000).
