Photochromic Inorganic-Organic Complex Derived from Low-cost Deep Eutectic Solvents with Tunable Photocurrent Responses and Photocatalytic Properties

Abstract

Growing interest in photochromic materials has largely stimulated the research in this field to synthesize inorganic-organic materials that composed of photochromic molecules such as viologen derivatives, naphthalene diimide (NDI) derivatives, and diarylethene derivatives. However, the requirement of elaborate structural design, complicated synthesis, and high cost remain the issues that need to be addressed before the photochromic materials can be accepted by the market. The synthesis using low-cost deep-eutectic solvents (DESs) may offer new opportunities to provide cost-effective reaction routes for the large-scale synthesis of photochromic materials. We present a multifunctional photochromic inorganic-organic complex |C10H10N2|[GaF(C2O4)2], which is constructed by nonphotochromic 4,4′-bipyridine ligand and oxalate derived from low-cost DESs components. The complex exhibits intriguing photochromic behavior with a wide range of photo-response from UV to visible light and ultralong-lived charge-separated state. Moreover, it possesses unprecedented tunable photocurrent responses and photocatalytic properties.
