Welcome to the Aprahamian Research Group

Research in the group focuses on using modular, and tunable hydrazone-based building blocks in the development of structurally simple adaptive functional materials, e.g., molecular switches, fluorophores and sensors. For this purpose synthetic organic and organometallic chemistry is used in conjunction with advanced spectroscopic and computational methods.

Our interest in controlling molecular motion and converting it into mechanical work has driven us to the development of new hydrazone-based molecular switches that can be activated either chemically or photochemically. These novel systems are expected to form the basis of various molecular machines and motors.

The group is also developing new hydrazone-based fluorophores (i.e., solid-state BODIHY dyes, and blue-light emitting Triazolopyridinium salts) that can be used in sensing, bio-imaging, and OLED applications, among others.
