Summary: Molecular trees and geochemical markers suggest the divergence of dinoflagellates as early eukaryotes around 650 million years ago. However, the traditional fossil record of dinoflagellate cysts begins during the Triassic about 230 million years ago. A re-evaluation of the pre-Triassic record reveals that many microfossils called acritarchs are actually dinoflagellate cysts, representing missing fossil evidence. Traditional diagnostic criteria for dinoflagellate cysts were biased towards thecate species, but a new approach based on comparing with living cysts includes athecate species. The earliest acritarchs had a cell wall made of sporopollenin-like material, which provided survival advantages in a microbial-dominated world.

Summary: The synthesis and characterization of heteroleptic ruthenium (II) complexes with donor functionalized phenyl-terpyridine and monocarboxylic groups have shown potential for photovoltaic applications. Excitation of these complexes under visible light results in metal-to-ligand charge transfer transitions, with implications for preventing back electron transfer in oxidized states and a relatively rapid excited-state decay following the energy gap law. These findings suggest promising photosensitizing abilities in these complexes and warrant further investigation for their potential use in photovoltaic devices.

Summary: This article presents the syntheses of ruthenium (II) complexes with an N-heterocyclic carbene (NHC)-based C and N donor set and an -NCS ligand, and evaluates their use as photosensitizers in dye-sensitized solar cells (DSSCs). Results show that the complexes without a phenyl spacer between the acid anchor and the tpy effectively absorb visible light and have higher photon conversion efficiency (PCE) in DSSCs.

Summary: This report describes ruthenium (II) complexes with novel ligands that exhibit tunable photo-functional properties. By introducing different ligands, the absorption wavelength range of the complexes can be extended, and the electron transfer efficiency can be improved. The presence of phenyl spacers results in a red-shift in the absorption wavelength, but the absence of phenyl spacers leads to better charge transfer and higher photon conversion efficiency.

Summary: We report heteroleptic ruthenium complexes of terpyridine (tpy) ligands with directly linked carboxylic acid anchors, featuring donor ligands of methyl or methoxy-substituted (4'-Ph)tpy. These complexes, prepared via a milder route to avoid homoleptic complex formation, exhibit visible light absorption with metal and ligand-to-ligand charge transfer excitations at approximately 490 nm. We evaluate the impact of tpy donor substituents on their light-harvesting ability in Dye-Sensitized Solar Cells (DSSCs) and compare their photosensitizing ability with heteroleptic complexes containing a phenyl spacer at the acceptor end. Additionally, we investigate their photovoltaic performance and electron transfer kinetics in DSSCs through electrochemical impedance spectroscopy, presenting the structure-photosensitization relationship of these heteroleptic ruthenium complexes using a combination of experimental and computational approaches.

Summary: We report a series of heteroleptic ruthenium(ii) complexes with N-heterocyclic carbene-based C<^>N donor sets functionalized with long hydrophobic chains ((n)decyl and (n)octyl) and -NCS ligands. These complexes utilize mono or tri-carboxy terpyridine (tpy) ligands as anchors to bind with TiO2 photoanodes. The synthetic route selectively yields complexes with NHC and -NCS ligands in trans-orientation. The complexes exhibit a wider visible-light absorptivity tailing until 750 nm. Strong electron donation from the C<^>N donor set and an -NCS ligand promotes metal-ligand-to-ligand charge transfer excitations, transferring electron density towards the carboxylate anchors. We evaluate the performance of these NHC-based ruthenium complexes in a typical dye-sensitized solar cell setup. The electrochemical and photophysical properties of the complexes highlight their ability to convert solar energy into electricity. Moreover, interfacial electron transport parameters obtained from electrochemical impedance spectroscopy provide deeper insights into the device performance. We also present electronic-structure calculations to support the experimental results.
