Sulfonamides in Organic Electronics - Blue-Emitting Helicene

Compared to red and green emitters, organic luminogens that emit standard- and deep-blue light remain challenging to design. Our recently published π-conjugated helicene is a deep-blue fluorophore in solution and the solid-state, with PL efficiency more than twice enhanced in the latter. This new sulfonamide / sultam-based motif introduces a brand new weapon to the arsenal of blue-emitting building blocks (e.g. triphenylethene, triarylamine-based systems). While common in pharmaceutical chemistry, sulfonamides are rare guests in organic electronics and thus represent a tantalizing possibility to explore.

Sulfonamides for Organic Electronics - Deep-Blue Emitter

My team recently reported a sulfonamide-based blue-emitting organic fluorophore that exhibits crystallization-induced emission enhancement.[1] Sulfonamides remain highly underutilized as functional groups in organic electronics and should be further explored as versatile molecular motifs for engineering structure-property-function relationships.
