Aggregation-induced emission (AIE) materials find their applications in organic optoelectronics, bio-imaging and sensors. In this work, we introduced alkyl substituents in AIE-active bis(4-((9H-fluoren-9-ylidene)methyl)phenyl)thiophene and elucidated thei

The reaction of various lithium fluorenyl compounds, Li(C13H7R1R2) (R1R2=H, alkyl or aryl) (1a-1n), with C5H5ZrCl3 leads to unbridged fluorenyl complexes of the type (C5H5)C13H7R1R2)ZrCl2 (2a-2n) which can be converted to the corresponding metallocene dimethyl complexes (3a-3e).In combination with methylaluminoxane (MAO), 2a-2n show a higher catalytic activity as homogeneous eethylene polymerization catalysts than (C5H5)2ZrCl2.Compound 2d (R1=2-Me; R2=7-Me) was charcterized by an X-ray structure analysis.Keywords: Metallocene; Fluorenyl ligands; Olefin polymerization; Zirconium
