• was performed using a Perkin-Elmer luminescence spectrometer LS50B. IR spectra were recorded on a Bruker Vector 22 using ATR technology. Elemental analysis was carried out on Elementar Varia El (Analytik Jena). GC-MS investigations were carried out on a Shimadzu GCMS-QP5050 with an AOC-20i Autosampler

• materials with more and more challenging requirements such as improved charge transport, luminescence, chirality and biological functions for high-tech applications has been directed towards the use of new mesomorphic systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Design principles based only on

• -one) as a cyclometallating ligand and from the suitably functionalized curcumin β-diketonate as a complementary O,O chelating ligand (Figure 1). The presence of the principal ligand [39][40][41][42][43][44] introduces interesting luminescence properties into the metallic system (which is luminescent

• organized into columns, the broad thermal stability and the luminescence in the red region of the visible spectrum make this new Pd(II) complex a very intriguing candidate for applications in OLED devices. A further class of ortho-palladated complexes has been obtained starting from the 2-phenylquinoline, a
