A new synthetic procedure for fluorinated N-fused ring, 2F-fluorazone (1,2-difluoro-9H-pyrrolo[1,2]-indol-9-one), has been developed. It connected with acetylene to obtain the first example of fluorinated N-fused rings luminescent liquid crystals (LLCs). CH3O-fluorazone-2F and CH3O-fluorazone displa...
