Abstract
The maximum range of perpendicular momentum transfer (q z) has been tripled for X-ray scattering from liquid surfaces when using a double-crystal deflector setup to tilt the incident X-ray beam. This is achieved by employing a higher-energy X-ray beam to access Miller indices of reflecting crystal atomic planes that are three times higher than usual. The deviation from the exact Bragg angle condition induced by misalignment between the X-ray beam axis and the main rotation axis of the double-crystal deflector is calculated, and a fast and straightforward procedure to align them is deduced. An experimental method of measuring scattering intensity along the q z direction on liquid surfaces up to q z = 7 Å-1 is presented, with liquid copper serving as a reference system for benchmarking purposes.

Abstract
Porphyrins have been vastly explored and applied in many cutting-edge fields with plenty of encouraging achievements because of their excellent properties. As important derivatives of porphyrins, porphyrin-based amphiphiles (PBAs) not only maintain the advanced properties of porphyrins (catalysis, imaging, and energy transfer) but also possess self-assembly and encapsulation capability in aqueous solution. Accordingly, PBAs and their self-assembles have had important roles in diagnosing and treating tumors and inflammation lesions in vivo, but not limited to these. In this article, we introduce the research progress of PBAs, including their constitution, structure design strategies, and performances in tumor and inflammation lesion diagnosis and treatments. On that basis, the defects of synthesized PBAs during their application and the possible effective strategies to overcome the limitations are also proposed. Finally, perspectives on PBAs exploration are updated based on our knowledge. We hope this review will bring researchers from various domains insights about PBAs.

Abstract
The photosensitizer Phenalenone (PN) was grafted with one or two lipid (C18) chains to form pure nano-assemblies or mixed lipid vesicles suitable for photodynamic therapy. Mixtures of PN-C18 conjugates with stearoyl-oleoyl phosphatidylcholine (SOPC) form vesicles that disintegrate into bilayer sheets as the concentration of PN-C18 conjugates increases. We hypothesized that PN-C18 conjugates control the thermodynamic and structural properties of the mixtures and induce the disintegration of vesicles due to PN π-π-interactions. Monolayers were analyzed by surface pressure and grazing incidence X-ray diffraction (GIXD) measurements, and vesicles by differential scanning calorimetry and cryo-TEM. The results showed that PN-triazole-C18 (1A) and PN-NH-C18 (1B) segregate from the phospholipid domains. PN-(C18)2 (conjugate 2) develops favorable interactions with SOPC and distearoyl-phosphatidylcholine (DSPC). GIXD demonstrates the contribution of SOPC to the structuring of conjugate 2 and the role of the major component in controlling the structural properties of DSPC-conjugate 2 mixtures. Above 10 mol% conjugate 2 in SOPC vesicles, the coexistence of domains with different molecule packing leads to conjugate segregation, vesicle deformation, and the formation of small bilayer discs stabilized by the inter-bilayer π-π stacking of PN molecules.

Abstract
Lipid-porphyrin conjugates are versatile compounds which can self-assemble into liposome-like structures with multifunctional properties. Most of the conjugates that have been described so far, consisted in grafting pyropheophorbide-a (Pyro-a) or other porphyrin derivatives through the esterification of the hydroxyl group in the sn-2 position of a lysophosphatidylcholine. However, despite the versatility of these conjugates, less is known about the impact of the lipid backbone structure on their 2D phase behavior at the air/water interface and more precisely on their fine structures normal to the interface as well as on their in-plane organization. Herein, we synthesized a new lipid-porphyrin conjugate (PyroLSM) based on the amide coupling of Pyro-a to a lysosphingomyelin backbone (LSM) and we compared its interfacial behavior to that of Pyro-a and Pyro-a conjugated lysophosphatidylcholine (PyroLPC) using Langmuir balance combined to a variety of other physical techniques. Our results provided evidence on the significant impact of the lipid backbone on the lateral packing of the conjugates as well as on the shape and size of the formed domains. Compared to Pyro-a and PyroLPC monolayers, PyroLSM exhibited the highest lateral packing which highlights the role of the lipid backbone in controlling their 2D organization which in turn may impact the photophysical properties of their assemblies.

Abstract
Phospholipid-Porphyrin (PL-Por) conjugates are unique building blocks that can self assemble into liposome-like structures with improved photophysical properties compared to their monomeric counterparts. The high packing density of porphyrin moieties enables these assemblies to exhibit high photothermal conversion efficiency as well as photodynamic activity. Thus, PL-Por conjugates assemblies can be used for photodynamic therapy (PDT) and photothermal therapy (PTT) applications against resistant bacteria and biofilms. In order to tune the PD/PT properties of such nanosystems, we developed six different supramolecular assemblies composed of newly synthesized PL-Por conjugates bearing either pheophorbide-a (PhxLPC) or pyropheophorbide-a (PyrxLPC) photosensitizers (PSs) for combined PDT/PTT against planktonic bacteria and their biofilms. In this study, the influence of the chemical structure of the phospholipid backbone as well as that of the PS on the photothermal conversion efficiency, the photodynamic activity and the stability of these assemblies in biological medium were determined. Then their antimicrobial efficiency was assessed on S. aureus and P. aeruginosa planktonic cultures and biofilms. The two studied systems show almost the same photothermal effect against planktonic cultures and biofilms of S. aureus and P. aeruginosa. However, PhxLPC vesicles exhibit superior photodynamic activity, making them the best combination for PTT/PDT. Such results highlight the higher potential of the photodynamic activity of PL-Por nanoassemblies compared to their photothermal conversion in combating bacterial infections.

Abstract
Phospholipid-porphyrin conjugates (PL-Por) are nowadays considered as a unique class of building blocks that can self-assemble into supramolecular structures that possess multifunctional properties and enhanced optoelectronics characteristics compared to their disassembled counterparts. However, despite their versatile properties, little is known about the impact of the packing parameter of PL-Por conjugates on their assembling mechanism and their molecular organization inside these assemblies. To gain a better understanding on their assembling properties, we synthesized two new series of PL-Por conjugates with different alkyl sn2-chain lengths linked via an amide bond to either pheophorbide-a (PhxLPC) or pyropheophorbide-a (PyrxLPC). By combining a variety of experimental techniques with molecular dynamics (MD) simulations, we investigated both the assembling and optical properties of the PL-Por either self-assembled or when incorporated into lipid bilayers. We demonstrated that independently of the linker length, PhxLPC assembled into closed ovoid structures, whereas PyrxLPC formed rigid open sheets. Interestingly, PyrxLPC assemblies displayed a significant red shift and narrowing of the Q-band indicating the formation of ordered J-aggregates. The MD simulations highlighted the central role of the interaction between porphyrin cores rather than the length difference between the two phospholipid chains in controlling the structure of the lipid bilayer membranes and thus their optical properties. Indeed, while PhxLPC have the tendency to form inter-leaflet π-stacked dimers, PyrxLPC conjugates formed dimers within the same leaflet. Altogether, this work could be used as guidelines for the design of new PL-Por conjugates that self-assemble into bilayer-like supramolecular structures with tunable morphology and optical properties.
