“…Thus in this paper, we take ReCl(CO) 3 (H 2 bpydt) (1) and ReCl(CO) 3 (H 2 bpyTTF) (3) as parent models, and theoretical calculations were employed to reform the system by adjusting the number of COOH group and their attaching point on ppy ligand (four COOH groups in 2 and three COOH groups in 4, see Fig. 1) in order to enhance the performance of the dyes.…”

The series of rhenium (I) tricarbonyl mixedligand complexes ReCl(CO) 3 (H n bpydt) (n = 2, 1; n = 4, 2; bpy = bispyridine, dt = 1,3-dithiole) and ReCl(CO) 3 (H n bpyTTF) (n = 2, 3; n = 3, 4; TTF = Tetrathiafulvalene) have been investigated theoretically to explore the effect of COOH functional group on their electronic structures, spectroscopic properties and their properties as dye in a solar cell. The calculated geometry structure and absorption spectrum of 1 and 3 are generally consistent with the experimental results. By attaching the COOH groups on both bpy and dt (TTF in 4) moiety in 2, the nature of LUMO is also contributed by both p*(bpy) and p*(dt) (p*(TTF) in 4), and the absorptions have an obvious red shift compared with 1 and 3. In addition, it can be found that the transition terminates at the orbital populated by the COOH-appended moieties, and the performance of 2 and 4 in the dye-sensitized solar cell can be enhanced as compared with 1 and 3.

“…In contrast to the great number of studies concerning metal complexes with 2,6-bis (3,5-dimethyl-N-pyrazolyl)pyridine (bdmpp), very little is known about complexes of btmpp, although this class of ligands could offer unique features in terms of structural and physical properties [1]. Papers dealing with the structures of mononuclear Co(II) complexes [5], the structures and electrochemical properties of Ni(II) dinuclear complexes [6], the structure and electrochemical properties of a Cu(II) nitrato complex [7], Ru(II) complex structures [8], and dye-sensitized solar cell efficiency using similar ligands have been published. Following our systematic study on the coordination chemistry of btmpp with transition metals [9,10], here we report the synthesis and structural characterization of new metal-coordination compounds with the pyrazole derivative ligand btmpp.…”

materials, which inevitably raises several significant problems in synthetic energy consumption, metal resource crisis, and environmental footprint. [2,3] Against this backdrop, organic materials have become significantly attractive owing to their unique merits of structural diversity, designability, low production cost, and minimum footprint in nature. [4][5][6][7] In the past decade, organic compounds with redox-active centers, including quinones, [8] carboxylates, [9] imines, [10] alkenes, [11] alkynes, [12] azo-, [13] organosulfur-, [7] and radical-groups, [2] have been intensively studied as potential anode/cathode materials for Li-ion batteries and other alkali cation-based batteries. [2,7] As battery researchers are moving in this new direction, it is of much importance to revisit organic electrode materials with a comprehensive perspective for addressing their practical roadblocks. Even though many promising organic electrode materials have been proposed by molecular design, most of them still suffer from low component utilization [14] and sluggish reaction kinetics. [15] It is intrinsically attributed to too localized active sites of charged atoms in specific functional groups such as CX and CXY (X, Y = O, N, S, P). [16] On one hand, the vast majority of organic electrode materials are based on redox chemistry at functional groups, while other components in Organic electrode materials have shown extraordinary promise for green and sustainable electrochemical energy storage devices, but usually suffer from low specific capacity and poor rate capability, which is largely caused by inactive components and diffusion-controlled Li + intercalation. Herein, high-rate Li + intercalation pseudocapacitance in organic molecular crystals is achieved through introducing weak secondary bonding channels, far exceeding their theoretical capacity based on redox chemistry at functional groups. The authors' combined experimentally electrochemical characterization with first-principles calculations show that the heterocyclic organic molecule 2,2′-bipyridine-4,4′-dicarboxylic acid (BPDCA) crystal permits a four-electron redox reaction at conventional CO and CN groups and a six-electron intercalation pseudocapacitance along conjugated alkene hydrogen bonding channels (H 2 NC 5 H⋯OC(OH)) and heterocyclic aromatic stacking channels (C 5 H 3 N⋯NH 3 C 5 ). The BPDCA electrode delivers an ultrahigh reversible capacity of 1206 mAh g -1 at 0.5 A g -1 and an exceptional rate capability. A 4.8 V high-energy/power-density BPDCA anode-based hybrid Li-ion capacitor is thus realized. This work opens a new avenue for developing organic intercalation pseudocapacitive materials via secondary bonding structure design.
