Strong‐binding host–guest pairings in aqueous media have potential as “supramolecular glues” in biomedical techniques, complementing the widely‐used (strept)avidin‐biotin combination. We have previously found that squaraine dyes are bound very strongly by tetralactam macrocycles possessing anthracenyl units as cavity walls. Here we show that replacing the anthracenes with pentacyclic 5,7,12,14‐tetrahydro‐5,7,12,14‐tetraoxapentacene (TOP) units generates receptors which bind squaraines with increased affinities (around

Abstract K a=1010m −1) and improved selectivities. Binding can be followed through changes to squaraine fluorescence and absorbance. The TOP units are easy to prepare and potentially variable, while the TOP‐based receptor shows improved photostability, both in itself and in complex with squaraines. The results suggest that this system could prove valuable in the further development of practical “synthavidin” chemistry. -
Abstract We investigated the effect of the cation‐π interaction on the susceptibility of a tryptophan model system toward interaction with singlet oxygen, that is, type II photooxidation. The model system consists of two indole units linked to a lariat crown ether to measure the total rate of removal of singlet oxygen by the indole units in the presence of sodium cations (i.e. indole units subject to a cation‐π interaction) and in the absence of this interaction. We found that the cation‐π interaction significantly decreases the total rate of removal of singlet oxygen (
k T) for the model system, that is, (k T = 2.4 ± 0.2) × 108m −1 s−1without sodium cationvs (k T = 6.9 ± 0.9) × 107m −1 s−1upon complexation of sodium cation to the crown ether. Furthermore, we found that the indole moieties undergo type I photooxidation processes with triplet excited methylene blue; this effect is also inhibited by the cation‐π interaction. The chemical rate of reaction of the indole groups with singlet oxygen is also slower upon complexation of sodium cation in our model system, although we were unable to obtain an exact ratio due to differences of the chemical reaction rates of the two indole moieties. -
Abstract The properties of warm-hot gas around ∼
L *galaxies can be studied with absorption lines from highly ionized metals. We predict Neviii column densities from cosmological zoom-in simulations of halos with masses in ∼1012and ∼1013M ☉from the Feedback in Realistic Environments (FIRE) project. Neviii traces the volume-filling, virial-temperature gas in ∼1012M ☉halos. In ∼1013M ☉halos the Neviii gas is clumpier, and biased toward the cooler part of the warm-hot phase. We compare the simulations to observations from the COS Absorption Survey of Baryon Harbors (or CASBaH) and COS Ultraviolet Baryon Survey (or CUBS). We show that when inferring halo masses from stellar masses to compare simulated and observed halos, it is important to account for the scatter in the stellar-mass–halo-mass relation, especially atM ⋆≳ 1010.5M ☉. Median Neviii columns in the fiducial FIRE-2 model are about as high as observed upper limits allow, while the simulations analyzed do not reproduce the highest observed columns. This suggests that the median Neviii profiles predicted by the simulations are consistent with observations, but that the simulations may underpredict the scatter. We find similar agreement with analytical models that assume a product of the halo gas fraction and metallicity (relative to solar) ∼0.1, indicating that observations are consistent with plausible circumgalactic medium temperatures, metallicities, and gas masses. Variants of the FIRE simulations with a modified supernova feedback model and/or active galactic nuclei feedback included (as well as some other cosmological simulations from the literature) more systematically underpredict Neviii columns. The circumgalactic Neviii observations therefore provide valuable constraints on simulations that otherwise predict realistic galaxy properties. -
Abstract This study addresses how the incidence rate of strong O
vi absorbers in a galaxy’s circumgalactic medium (CGM) depends on galaxy mass and, independently, on the amount of star formation in the galaxy. We use Hubble Space Telescope/Cosmic Origins Spectrograph absorption spectroscopy of quasars to measure Ovi absorption within 400 projected kpc and 300 km s−1of 52 galaxies withM *∼ 3 × 1010M ⊙. The galaxies have redshifts 0.12 <z < 0.6, stellar masses 1010.1M ⊙<M *< 1010.9M ⊙, and spectroscopic classifications as star-forming or passive. We compare the incidence rates of high column density Ovi absorption (N OVI ≥ 1014.3cm−2) near star-forming and passive galaxies in two narrow ranges of stellar mass and, separately, in a matched range of halo mass. In all three mass ranges, the Ovi covering fraction within 150 kpc is higher around star-forming galaxies than around passive galaxies with greater than 3σ -equivalent statistical significance. On average, the CGM of star-forming galaxies withM *∼ 3 × 1010M ⊙contains more Ovi than the CGM of passive galaxies with the same mass. This difference is evidence for a CGM transformation that happens together with galaxy quenching and is not driven primarily by halo mass. -
Abstract We present a four-step group-finding algorithm for the Gas in Galaxy Groups (G3) initiative, a spin-off of the
z ∼ 0 REsolved Spectroscopy Of a Local VolumE (RESOLVE) and Environmental COntext (ECO) surveys. In preparation for future comparisons to intermediate redshift (e.g., the LADUMA survey), we design the group finder to adapt to incomplete, shallow, or nonuniform data. We use mock catalogs to optimize the group finder’s performance. Compared to friends-of-friends (with false-pair splitting), the G3 algorithm offers improved completeness and halo-mass recovery with minimal loss of purity. Combining it with the volume-limited Hi census data for RESOLVE and ECO, we examine the Hi content of galaxy groups as a function of group halo mass. Group-integrated Hi massM H I,grprises monotonically over halo massesM halo∼ 1011–1014.5M ⊙, pivoting in slope atM halo∼ 1011.4M ⊙, the gas-richness threshold scale. We present the first measurement of the scatter in this relation, which has a median of ∼0.3 dex and is asymmetric toward lowerM H I,grp. We discuss interesting tensions with theoretical predictions and prior measurements of theM H I,grp–M halorelation. In an appendix, we release RESOLVE DR4 and ECO DR3, including updates to survey redshifts, photometry, and group catalogs, as well as a major expansion of the ECO Hi inventory with value-added data products.
