Syntheses, structures and photoluminescence properties of a series of metal–organic complexes with 1,3-benzenedicarboxylate and 10,11,12,13-tetrahydro-4,5,9,14-tetraaza-benzo[b]triphenylene ligands

Syntheses and characterization of four coordination compounds derived from 10,11,12,13-tetrahydro-4,5,9,14-tetraaza-benzo[b]triphenylene and benzene-dicarboxylic acids

“…As indicated in figure 9, the maximum emission wavelength occurs at 612 nm for 2 and 526 nm for 4 upon excitation at 365 nm. To understand these emission bands, luminescent properties of free 1,3-H 2 BDC, 1,4-H 2 BDC, and TTBT were analyzed, showing they exhibit strongest emission peaks at 382 nm, 378 nm [16], and 549 nm [17], respectively. On complexation of the ligands with Pb 2þ , the emission was not observable.…”

“…Also, 1,10-phenanthroline (phen) and derivatives have been widely used to build supramolecular architectures owing to large conjugated systems that can easily form -interactions [11][12][13][14][15]. 10,11,12,5,9, triphenylene (TTBT) is an important derivative of phen; to the best of our knowledge, coordination compounds constructed by TTBT have rarely been reported [16,17]. During our preparation of MOFs based on TTBT in combination with aromatic carboxylates, [Co 2 (TTBT) 4 …”

“…Currently, the design and synthesis of metal-organic frameworks (MOFs) are of great interest owing to their intriguing variety of architectures and their tremendous potential applications in many fields (Chen et al, 2009;Rosi et al, 2003;Su et al, 2004;Xiao et al, 2006). As a multidentate ligand, benzene-1,3-dicarboxylic acid (m-H 2 BDC) has two carboxyl groups and, therefore, has been widely reported as a good candidate not only in the construction of various coordination polymers but also in the construction of MOFs with multi-dimension (Banerjee et al, 2008;Che et al, 2009;Clegg & Russo, 2009;Li et al, 2008;Su et al, 2009;Zhao, 2008).…”
