“…It has been reported that these metallopolyynes are white powders and they possess high transparency towards visible light, which properties, plus their good solution processability, make them good candidates for OPL materials. Although Ru 2+ and Zn 2+ complexes with terpyridines have been reported with good NLO properties and large TPA cross section, which could be used for their application as OPL materials, their strong absorption in the visible region currently limits their use as optical limiters, though it may be possible to obtain polymers with suitable properties by choosing the right ligands.…”

Due to their inherently dynamic natures and fascinating photoluminescent/photoelectronic properties, coordination compounds of metal ions and conjugated terpyridine ligands have attracted considerable attention as functional materials for a variety of potential applications. In this feature article, a summary of recent work toward the development of one- (1D), two- (2D), and three-dimensional (3D) supramolecular polymers, networks, and metallomacrocycles based on zinc metal ion coordination of conjugated units bearing terpyridine ligands is presented, and it is shown how it fits within the overall framework of work in this field. Here, a sequential study from terpyridines as basic building blocks to their zinc-coordinated supramolecular 1D polymers, 2D macrocycles, and 2D and 3D networks is developed. These networks are compared with respect to their thermal stabilities, molecular organization, and linear and nonlinear optical properties. This work opens new prospects for the development of supramolecular chemistry of terpyridines and other transition metal ions, and also their application in future optoelectronic devices.

“…Two-photon absorption dyes 2995 dye 3 formed a 2-D framework through π-π stacking interactions (green dashed line, the shortest distance is 3.475 Å, plum dashed line, the shortest distance is 3.035 Å) between the neighboring dimers along the c-axis. In addition, C-HÁ Á ÁI interactions (d (H33Á Á ÁI2) [15], which is assigned to π-π ⁄ transitions [16]. The absorption profile and maxima of all of the compounds are almost identical in different solvents, suggesting that ground state electronic structures are independent of solvent polarity and small dipole moments associated with the ICT transitions.…”

A series of new cadmium complexes (dyes 1-5) were obtained by assembly of the donor-bridgeacceptor (D-π-A)-type ligand (L: 4′-(4-[4-(imidazole)styryl]phenyl) 2,2′ : 6′,2″-terpyridine) with CdX 2 (X=Cl, Br, I, NCS, ClO 4 ), in which dye 3 was characterized by single crystal X-ray diffraction. Various weak interactions, including hydrogen bonds (C-HÁ Á ÁN, C-HÁ Á ÁX) and π-π interactions, played significant roles in the final topological structures. Linear and non-linear optical properties of ligand and the complexes were investigated. The two-photon absorption cross-section of these complexes are larger than that of ligand with maximum values of 577 GM (dye 1), 242 GM (dye 2), 171 GM (dye 3), 326 GM (dye 4), and 215 GM (dye 5) in N,N-dimethylformamide. IntroductionMaterials with intense two-photon absorption (TPA) have received attention as the most promising candidates for novel optical materials; their variety of potential applications includes three-dimensional microfabrication [1], information technology [2], laser technology [3], biological system imaging [4], etc. However, the bottleneck of application of TPA materials is the generally small TPA cross-sections (δ). TPA is a third-order non-linear optical (NLO) phenomenon, and the efficiency of this process is determined by measuring δ values, which urged us to synthesize materials with large TPA cross-sections. Several strategies were proposed to improve TPA response, such as taking both intramolecular and intermolecular approaches to enhance TPA efficiency [5], connecting donor and acceptor symmetrically or unsymmetrically by π-conjugated bridges to form D-π-D, A-π-A, or D-π-A structures and the building of multibranched molecules [6], which can

“…This is accounted for the terpyridine unit mobility, which can adopt different conformations, breaking the chain conjugation. According to the literature [35] three different conformations can be assigned to this group: cis-cis, trans-trans and cis-trans which in turn would result in changes of the energy levels in the excited state, depending on the chemical environment.…”

This work reports the synthesis and characterization of a conjugated polymer based on fluorene and terpyridine, namely, poly[(9,9-bis(3-((S)-2-methylbutylpropanoate))fluorene-alt-6,6′-(2,2′:6′,2′′-terpyridin-6-yl)] (LaPPS71). The structure was characterized by 1H and 13C nuclear magnetic resonance (NMR) and Fourier-transform infrared (FTIR) spectroscopy. The molar mass was measured by gel permeation chromatography (GPC). As thermal characterization, the glass transition temperature (Tg) was measured by differential scanning calorimetry (DSC). The polymer structure contains two sites capable of complexation with metallic ions, affording the possibility of obtainment of independent or electronically coupled properties, depending on the complexation site. The photophysical properties were fully explored in solution and solid state, presenting ideal results for the preparation of various metallopolymers, in addition to potential application as a metamaterial, due to the presence of the chiral center in the side chains of the polymer.
