Effect of the organic fragment on the mesogenic properties of a series of organogold(I) isocyanide complexes. X-ray crystal structure of [Au(CCC5H4N)(CNC6H4O(O)CC6H4OC10H21)]

Study of the Effect of the Phosphane Bridging Chain Nature on the Structural and Photophysical Properties of a Series of Gold(I) Ethynylpyridine Complexes

“…Commercial reagents PPh 3 , dppa, dppbz, dppf, dppp and 4-bromopyridine hydrochloride were used as received. Literature methods were used to prepare [AuCl(tht)], [63] [Au(CϵCC 5 H 4 N)] n , [4] NC 5 H 4 CϵCH, [64] dppm, [65] dppip, [32] dppe [65] and dppb. [65] Physical Measurements: Infrared spectra were recorded with a FTIR 520 Nicolet spectrophotometer.…”

“…During the past years, there has been a continued interest in the chemistry of alkynyl gold(I) complexes, primary resulting from their interesting physical properties such as nonlinear optical behaviour, [1][2][3] liquid-crystalline properties [4,5] and photoemissive properties of the molecules and their aggregates. [6][7][8][9][10][11][12] Moreover, the low steric congestion about the linear gold(I) centre and the ability of gold(I) to form attractive Au···Au interactions have made alkynyl gold(I) compounds attractive candidates for the synthesis of a wide variety of supramolecular structures [13] as polymers, [14][15][16][17] macrocycles [18][19][20] or catenanes.…”

Photoactive building blocks for coordination complexes: Gilding 2,2′:6′,2″-terpyridine

“…The luminescent properties of gold(I) species [13,14] and the ease of synthesis of gold(I) alkynyls make them attractive candidates for derivatization of other metal-binding domains such as pyridine [15][16][17][18][19], 2,2'-bipyridine (bpy) [16,20,21] and 2,2':6',2"-terpyridine (tpy) [21,22]. The combination of a luminescent gold(I) unit and a chelating ligand provides an approach to the design of metal ion sensors.…”

Synthesis and photophysical properties of luminescent mononuclear and dinuclear gold(I) complexes with ethynyl-substituted phenanthrolines

“…Extensive structural and photophysical studies of gold(I) ethynylarene complexes have been carried out in the past two decades [1][2][3][4]. By contrast, gold(I) complexes with ethynylpyridines and their derivatives have primarily been studied in relation to their structure and photophysical properties in the recent past [5][6][7][8][9][10]. In particular, the synthesis and photophysical study of gold(I) ethynyl-substituted polyimine complexes containing bipyridine or terpyridine has very recently been reported by Vicente et al [11], and the molecular structures consisting of linear two-coordination of several gold(I) ethynylsubstituted polyimine complexes were revealed by single crystal X-ray diffraction study.…”
