Crystals of this thiophene-based derivative, shown in an upside-down vial, glow when illuminated with ultraviolet light thanks to a phenomenon called aggregation-induced emission (AIE). Photoluminescent compounds display AIE if they emit light weakly in a solution but strongly in the solid state. Jayden Price, a PhD candidate at the University of New Brunswick, synthesized this derivative via a Suzuki-Miyaura cross-coupling reaction. “When going from solution to solid state, organic emitters often suffer from a complete or partial loss of their emission properties— rendering AIE a highly desirable property when designing small molecule building blocks with optoelectronic applications,” Price explains. He designs and synthesizes small, highly emissive building blocks for use in organic electronics.
