Cyclometalated palladium(II) metallomesogens with Schiff bases and N -benzoyl thiourea derivatives as co-ligands

Discotic Liquid Crystals Based on Cu(I) Complexes with Benzoylthiourea Derivatives Containing a Perfluoroalkyl Chain

“…e slight decomposition observed at temperatures higher than the clearing point could explain the transition temperatures shifting recorded by DSC. Similar observations were found for some palladium(II) complexes with mixed ligands, Schiff bases, and BTU derivatives, reported previously [59,60].…”

Columnar Liquid Crystals of Copper(I) Complexes with Ionic Conductivity and Solid State Emission

“…The reaction between metal salts and these versatile N -acylthiourea derivatives provides a variety of metal complexes, including both homoleptic and heteroleptic complexes. These ligands can act as a bidentate ligand in the monoanionic form through the O and S atoms or as a monodentate ligand via the thione S atom in the neutral form [ 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ].…”

Playing with PtII and ZnII Coordination to Obtain Luminescent Metallomesogens

“…on Ag I[16] and Zn II , Cârcu et al. on Pd II , Cano et al. on Ag I[21–22] and Pucci, Crispini and Ghedini et al.…”

“…Luminescent d-block metallomesogens are promising functional materials for practicala pplications.T hey have mainly been investigated in terms of obtaining polarised emission to be used as backlighting in displays, [1][2][3][4] but also some studies concerning their use as stimuli responsive materials for sensing [5,6] or security inks, [7] or high-hole mobility materials for electroluminescent devices [8] have been reported.D espite recentp rogress with square-planar Pt II and octahedral Ir III complexes, which are considered among the best emitters, there is still considerable work to be done to control the phase type and transition temperatures or to improvet he luminescence in the mesophase. [9] In fact, only af ew studies on the mesophases of luminescent liquid-crystalline transition metal complexes have been carried out, with, just to cite non-exhaustively,t he contributions of Bruce et al on Ir III , [8,[10][11][12] Espinet et al [13] and Tsutsumi et al [14,15] on Au I ,G imenØnez et al on Ag I [16] and Zn II , [17] Cârcu et al on Pd II , [18][19][20] Cano et al on Ag I [21][22] and Pucci, Crispini and Ghedini et al on Ru II , [23] Ag I , [24][25][26] Ir III [27] and Zn II [28,29] complexes. For practical applications,t echnological and economic issueshave to be taken into account,such as thermaland optical stabilities, availability and cost of the precursors and straightforward syntheses.…”
