A pure cis-2 isomer of indene dimer-based fullerene bis-adduct has been synthesized, isolated and applied to bulk heterojunction solar cells for the first time. The device based on the cis-2 isomer and poly(3-hexylthiophene) exhibited a power conversion efficiency of 2.8%, which is higher than those of the reference devices.
Umsetzungen des 1,2-Bis(3-indenyl)ethan-Dianions mit photochemisch aktivierten Carbonylkomplexen des Chroms, Molybdaens und Wolframs. Molekuelstrukturen von C9H7CH2CH2C9H7 und (η5:η5-C9H6CH2CH2C9H6)2

The 1,2-bis(3-indenyl)ethane dianion 2- reacts with the photochemically activated carbonyl complexes M(CO)5(thf) (M = Cr, Mo, W) to give the dinuclear anions 5 : η5-C9H6CH2CH2C9H6)2>2-.These dianions react with CH3I to yield the corresponding dinuclear complexes, (η5 : η5-C9H6CH2CH2C9H6)2 (M = Mo, W) and (η6 : η6-C9H6MeCH2CH2C9H6Me)2, and the mononuclear complex, (η6-C9H6MeCH2CH2C9H7)Cr(CO)3.The crystal structures of C9H7CH2CH2C9H7 and (η5 : η5-C9H6CH2CH2C9H6)2 have been determined.

Paragraph 0229-0230, (2021/09/11)
A method for preparing a compound comprising a cyclopentadienyl moiety is described. The method comprises: (a) deprotonating a cyclopentadienyl moiety in a solution comprising an alkali hydroxide and a reducing agent; and (b) reacting the deprotonated cyclopentadienyl moiety with a compound having an electrophilic site. Also described is a method of separating a rac-ansa-bridged bis-indenyl transition metal compound of formula (rac-M1) from its meso isomer.
