Self-Assembled Microdisk Lasers of Perylenediimides

Abstract: Organic solid-state lasers (OSSLs) have been a topic of intensive investigations. Perylenediimide (PDI) derivatives are widely used in organic thin-film transistors and solar cells. However, OSSLs based on neat PDIs have not been achieved yet, owing to the formation of H-aggregates and excimer trap-states. Here, we demonstrated the first PDI-based OSSL from whispering-gallery mode (WGM) hexagonal microdisk (hMD) microcavity of N,N'-bis(1-ethylpropyl)-2,5,8,11-tetrakis(p-methyl-phenyl)-perylenediimide (mp-PDI) … Show more

“…Appropriate modification of PDIs is needed to fabricate a balance between effective molecular stacking and retention of the desired fluorescence. Recently, PDI‐based OSSL from whispering‐gallery mode (WGM) hexagonal microdisk (hMD) microcavity of N , N ’‐bis(1‐ethylpropyl)‐2,5,8,11‐tetrakis( p ‐methyl‐phenyl)‐perylenediimide has been achieved due to the mp‐PDI molecules stack into a loosely packed twisted J‐type aggregates which exhibits moderate optical gain with a photoluminescence (PL) efficiency φ >15 % . Here, we obtained 1D nanowires also stacking into a loosely J‐type arrangement through proper molecular tailoring of PDI.…”
