The newly synthesized platinum containing poly-yne polymers exhibit good solubility in common organic solvents. These metal linked polymers were characterized by IR, ¹H NMR and ³¹P NMR spectroscopy.

Wong, Wai-Yeung published the artcileSynthesis and characterization of new oligoacetylenic silanes, Formula: C18H10, the publication is New Journal of Chemistry (2002), 26(3), 354-360, database is CAplus.

Synthetic routes to a series of novel oligoacetylenic silanes with or without (hetero)aromatic bridges have been developed. The compound Me₃SiC顚咰Si(Ph)₂C顚咰SiMe₃ was first prepared, which was selectively desilylated with CaCO₃ in methanol at room temperature to afford the mono-protected bis(alkynyl)silane Me₃SiC顚咰Si(Ph)₂C顚咰H in moderate yield. Treatment of this mono-protected species with ⁿBuLi, followed by silylation with Ph₂SiCl₂, gives a good yield of Me₃SiC顚咰Si(Ph)₂C顚咰Si(Ph)₂C顚咰Si(Ph)₂C顚咰SiMe₃, with alternating silicon and acetylene units. A range of linear silicon-linked oligoalkynes containing phenylene, bithienylene and anthrylene rings, HC顚咰RC顚咰Si(Ph)₂C顚咰RC顚咰H and HC顚咰RC顚咰Si(Ph)₂C顚咰RC顚咰Si(Ph)₂C顚咰RC顚咰H (R = 1,4-phenylene, 5,5′-bithienylene or 9,10-anthrylene), were synthesized by condensation reactions of Ph₂SiCl₂ with the components obtained in situ from a HC顚咰RC顚咰H-ⁿBuLi mixture in THF and the products were isolated by chromatog. on silica. All these new compounds have been characterized by IR, ¹H and ¹³C NMR and UV/VIS spectroscopies and mass spectrometry. The single-crystal x-ray structure of HC顚咰(p-C₆H₄)C顚咰Si(Ph)₂C顚咰(p-C₆H₄)C顚咰Si(Ph)₂C顚咰(p-C₆H₄)C顚咰H has been determined, showing that two silicon atoms and six acetylene units constitute the backbone of the mol.

Karafiloglou, Padeleimon published the artcileComparing electron (de)localization in the through benzene and anthracene charge transfer, Synthetic Route of 18512-55-5, the publication is Chemical Physics (2003), 289(2-3), 231-242, database is CAplus.

The contrasting behavior of benzene and anthracene in the through 蟺-system passing of a (+) charge is examined by considering para-diethynylbenzene and para-diethynylanthracene spacers. The (de)localization of their bonds in both neutral and cationic forms are compared by a two-electron population anal.; the electron-pair distributions are calculated in orbital spaces appropriate for population anal., as the natural AOs, in which two-electron correlations are also studied. When the spacer involves benzene, then its oxidation causes a reorganization of electron pairs towards a pronounced quinoid bond (de)localization, which induces analogous bond deformations; on the contrary, in the case of anthracene, a similar quinoid (de)localization (and the corresponding bond deformation) is impeded, due to the possibility of addnl. delocalization on its central ring. As shown, these electron-pair reorganizations are the driving force for the corresponding geometrical deformations.

Kempe, Hideto published the artcileEnormously extended 蟺-electronic conjugation system of dimeric octaethylporphyrin transmitted with anthracene, Application In Synthesis of 18512-55-5, the publication is Tetrahedron Letters (2014), 55(37), 5164-5169, database is CAplus.

Based on the fact that anthracene (Anth) possesses much higher similarity in electron-releasing ability to porphyrin nucleus than the other polyacenes, the dimeric octaethylporphyrin (OEP) derivatives 4 and 5 (OEP-Anth-OEP) were synthesized and their structure-property relations were examined, as compared with related OEP dimers 1-3. Among them, the derivative 4 showed enormously high electronic communication between two terminal OEP rings, potentially providing a suitable unit of the electronic structure for mol. design of the OEP devices operating with less energy and with higher sensitivity to outside stimuli.

Li, Yongjun published the artcileIntramolecular triplet energy transfer in anthracene-based platinum acetylide oligomers, Category: naphthyridine, the publication is Journal of Physical Chemistry B (2013), 117(30), 9025-9033, database is CAplus and MEDLINE.

Platinum acetylide oligomers that contain an anthracene moiety have been synthesized and subjected to photophys. characterization. Spectroscopic measurement and DFT calculations reveal that both the singlet and triplet energy levels of the anthracene segment are lower than those of the platinum acetylide segment. Thus, the platinum acetylide segment acts as a sensitizer to populate the triplet state of the anthracene segment via intramol. triplet-triplet energy transfer. The objective of this work is to understand the mechanisms of energy-transfer dynamics in these systems. Fluorescence quenching and the dominant triplet absorption that arises from the anthracene segment in the transient absorption spectrum of Pt4An give clear evidence that energy transfer adopts an indirect mechanism, which begins with singlet-triplet energy transfer from the anthracene segment to the platinum acetylide segment followed by triplet-triplet energy transfer to the anthracene segment.

Belyaev, Andrey published the artcileSolution versus solid-state dual emission of the Au(I)-alkynyl diphosphine complexes via modification of polyaromatic spacers, Safety of 9,10-Diethynylanthracene, the publication is New Journal of Chemistry (2019), 43(35), 13741-13750, database is CAplus.

Single mol. luminophores capable of multiple emissions are essential for the development of new materials with unconventional photophys. behavior. In this work, a family of diphosphine ligands PPh₂-PAH-PPh₂ with variable polyaromatic hydrocarbon (PAH) spacers (PAH = 9,10-anthracene L1, 1,4-naphthalene L2, 2,6-naphthalene L3, and their diethynyl congeners L4–L6) were employed to prepare gold(I) complexes (RC₂Au)PPh₂-PAH-PPh₂(AuC₂R) (1–22), containing a selection of alkynyl groups. Investigation of their optical properties indicates that compounds with anthracene-based diphosphines (1–4 and 13–16) display only ¹IL (蟺蟺*) fluorescence with 桅_em up to 93%. The naphthalene and diethynyl-naphthalene diphosphine complexes (5–12 and 17–22), however, demonstrate panchromatic emission in the solid state and in solution featuring well-separated low and high energy signals, which originate from ¹IL (蟺蟺*) and ³IL (蟺蟺*) transitions along with certain contribution from metal to ligand and ligand to ligand charge transfers.

In order to determine the microstructure of the polymer composed of 1,4-benzenedithiol with 9,10-diethynylanthracene, the model compounds cis– and trans-9,10-bis(phenylthiovinylene)anthracenes were prepared In comparison with the characteristic absorption peaks of vinylene in the model compounds, the microstructure of the polymer was evaluated. Regardless of the initiation mode, UV irradiation, AIBN and none, the cis contents of the polymers were 80-85%. The cis configuration of the polymer isomerized gradually to the trans one with increase of UV irradiation time. The characteristic features of the isomerization were also studied using model compounds The cis isomer of the model compound underwent irreversible isomerization to the trans one by UV irradiation In the presence of a radical source in the reaction system, both the cis and trans isomers can isomerize and reach an equilibrium state after reaction for a sufficient time. The isomerization mechanism was also discussed based on the potential energy diagram.
