Adjustment of electronic and emissive properties of indolocarbazoles for non-doped OLEDs and cholesteric liquid crystal lasers

Acridone and quinacridone derivatives with carbazole or phenoxazine substituents: synthesis, electrochemistry, photophysics and application as TADF electroluminophores

“…This difference cannot be attributed to solvatochromism but rather to a different combination of ICT and LE emissions, as previously reported for indolocarbazoletype emitters. 58,59 Thus, weakening of donor-acceptor interactions in compound 5 dispersed in mCP as compared to the film of neat luminophore (undoped EML) results in switching from ICT to LE emission, which is more intensive under electrical excitations than under optical ones.…”

Study of Liquid Crystal Cell Doped With Bodipy for Lasing Application

“…2, № 1, С. 102-109 (2022) developing reproducible and scalable protocols for both their synthesis and controlled crystallization followed by experimental validation have a significant impact on understanding of their physical properties [14][15][16]. Organic semiconductors have shown great potential as laser gain materials due to a combination of high available optical gain, solution processability and broad emission spectra [17].…”
