Abstract:
A variety of transformations involving C-C bond cleavage in iridium complexes is described. 1,1-Dimethylcyclopentane reacts with [IrH2(Me2CO)2L2]SbF6 (L = (p-FC6H4)3P, 1) to give first [(5,5-C5H4Me2)IrL2]SbF6 (2) and then [(MeC5H4)IrMeL2]SbF6 (3). The corresponding 5,5-dimethylcyclopentadiene gives 1,2- and 1,3-diethylcyclopentadienyl complexes by a route that involves alkyl migration from ring to metal and back. 4,4-Dimethylcyclopentene also reacts to give 3 but the 3,3-isomer follows a different path to give [(MeC5H4)IrHL2]SbF6. Crystal structures of two diene complexes of type 2 are reported and mechanisms for the reactions observed are proposed. © 1986 American Chemical Society.
Abstract:
The monolayer-forming properties of four generations of azobenzene-containing dendrons were investigated. The photochromic dendron for monolayer formation was used because of the potential ability to suppress crystallization of the photochromic fragments. All dendritic compounds can be spread on an air-water interface to form a stable monolayer. There ia a systematic increase in the cross-sectional area per molecule with increasing number of alkyl tails in the outer shell of dendrons.

A series of near-IR-absorbing soluble phthalocyanines (Pcs) with eight alkyne moieties as side chains of the chromophore have been synthesized. One of these Pcs has been used as a scaffold for functional group modification using alkyne-azide click chemistry with various azides. This led to a small library of Pcs with photo and thermal crosslinkable, dendritic, and hydrophilic moieties starting from a single Pc molecule. A patterned thin film was fabricated by photocrosslinking one of these Pc derivatives. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
