New Trends in the Design of Luminescent Metal Complexes*

Abstract

Abstract-The requirements needed for an ideal luminophore are discussed with reference to the luminescent properties of organic molecules and metal complexes. Recent strategies for the design of luminescent metal complexes are discussed, with particular emphasis on cage-type complexes and oligonuclear homo-and hetero-metallic complexes.

Study on synthesis, structure, and DNA-binding of Ni, Zn complexes with 2-phenylquinoline-4-carboylhydrazide

“…Among these modes, the groove binding mode plays an important role in the efforts of the drugs targeted to DNA [3]. Some of the transition metal complexes activate endonucleolytic cleavage reaction in DNA in the presence of external agents or photolytically [4][5][6][7]. These endonucleolytic cleavage of DNA by metal complexes are used as models for the reactivity of some antitumor antibiotics.…”

Luminescence quenching of *[Ru(bpy)3]2+ by ruthenium(II) tetraphosphite complexes with different phosphite ligands

“…The chemical and photochemical properties of Ru(II)-polypyridine complexes have attracted wide interest because of their excellent catalytic and photosensitive properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The interest is mainly due to their use as solar energy conversion, photochemical molecular devices, photodegradation reactions and luminescent sensors.…”

“…The rate constants of bimolecular reactions are functions of a variety of molecular and solvent parameters [10][11][12][13][14][15][16][19][20][21][22][23][24][25][26][27][28][29][30]. The driving force and the reorganizational free energy tend to be the most important [16,19,24,25,28], but factors such as donor/ acceptor electronic coupling, distance of closest approach and reagent charge type can also be important in determining variations of reaction rate constants in a series of related reactions [20,30].…”

From chemistry to materials, design and photophysics of functional terbium molecular hybrids from assembling covalent chromophore to alkoxysilanes through hydrogen transfer addition

“…Complexation of these ions by organic ligands, such as b-diketones, aromatic carboxylic acids, and heterocyclic derivatives, offers several advantages to design efficient light-conversion molecular device (LCMDs) [1][2][3][4]. In these systems, ligands absorbed light energy and transferred the absorbed energy to the emitting metal ion (the so-called antenna effect), thus markedly increasing the absorption coefficients [5].…”
