A highly efficient dehydrogenative reaction of a series of nucleophiles with 9-aryl-fluoren-9-ols has been realized by using only 2 mol% of Sc(OTf)3 as a catalyst. The corresponding indole-containing 9,9-diarylfluorenes were obtained in up to 99% yield as well as other electron-rich (hetero)arene adducts. The protocol exhibits high selectivity, mild reaction conditions and good substrate compatibility (32 examples). This protocol is further highlighted by its applications in the construction of potential electroluminescent materials.

supporting information; experimental part, p. 520 - 521 (2010/09/05)
A class of complicated 9,9-diarylfluorenes as nonplanar building blocks were synthesized and utilized to prepare a novel H-shaped oligofluorene. High glass transition temperatures and excellent solubility of the obtained oligomers indicated the 9,9diarylfluorenes would be promising building blocks for the construction of H-shaped optoelectronic materials.

A new family of host molecules, based on the singly bridged triarylmethanol and triarylacetic acid frameworks, is described.These hosts form crystalline inclusions with a variety of uncharged organic molecules ranging from protic dipolar to apolar compounds (130 different species).The formation and stoicheiometry depend in a systematic manner on structural parameters of the host, such as the nature of the functional group and the substituents, and on the substituent positions.The crystal structures of three inclusion compounds have been studied by X-ray diffraction.They reveal the building principles of the new inclusion family.In the crystals of 1a*benzene (8:3), the benzene is interstitially entrapped by H-bonded tetramer clusters of 1a.Crystals of 1a*dioxane (4:3) are built of H-bonded 2:1 host-guest complexes including interstitial molecules of dioxane.In the case of 4c*EtOH (1:1), the building principle is formation of 2:2 host-guest clusters via a twelve-membered H-bonded ring.
