Abstract
ABSTRACT
Nowadays, design and synthesis of coordination polymers have attracted great attention
because of their potential applications and correlated tightly with the material and information
science. At present work, we designed a anic ligand with excellent optical properties, as
well as functional plexes, which have both advantages anic and anic
units. Main research results were concluded as follow.
(1) The recent developments in the research for plexes and NLO materials in
worldwide were reviewed in the dissertation, based on a great deal of related literatures.
New concepts and design of our new plexes for the dissertation are presented.
(2) A novel pyridine ligands trans-4[4’-(N-methyl-N- hydroxyethyl)amimo]vinyl pyridine (L1)
was essfully synthesized, which were characterized by NMR, MS and IR spectra. The
results of optical property studies for pound revealed that it exhibits strong
luminescent emissions.
(3) A series of the novel plexes were obtained by self-assembling of L1 and
transition metal salts, such as M(SCN)n and MX(X = Cl, Br), in which there are
coordina
