Chen, Huan,Li, Shengliang,Wu, Min,Kenry,Huang, Zhongming,Lee, Chun-Sing,Liu, Bin
, p. 632 - 636 (2020)
Traditional photosensitizers (PSs) show reduced singlet oxygen (1O2) production and quenched fluorescence upon aggregation in aqueous media, which greatly affect their efficiency in photodynamic therapy (PDT). Meanwhile, non-targetin

Dibenzo[hi,st]ovalene (DBOV) has emerged as a new polycyclic aromatic hydrocarbon (PAH) with intriguing optical properties with strong red emission. Nevertheless, DBOV derivatives thus far synthesized either had mesityl groups that hinder the π-π stacking

Fischer indole reaction of Weiss diketone with 4-bromophenylhydrazine provided the 2,8-dibromo-hexahydropentaleno[2,1-b:5,4-b’]diindole key intermediate, which was converted to the target compounds by N-protection/Suzuki cross-coupling. Variation of prote

Wedge-shaped phenylphosphonic acids with variation in the peripheral alkoxy chains have been synthesized. These derivatives show a hexagonal columnar liquid-crystalline behavior upon thermal treatment. These materials have potential to be used as efficien
A Membrane-Intercalating Conjugated Oligoelectrolyte with High-Efficiency Photodynamic Antimicrobial Activity

A membrane-intercalating conjugated oligoelectrolyte (COE), PTTP, was designed and synthesized with the goal of providing red-shifted absorption spectra relative to previously synthesized COE analogs. Specifically, electron-rich and electron-poor subunits were introduced in the conjugated backbone to modulate the band gap. PTTP exhibits maxima of absorption at 507 nm and of emission at 725 nm. PTTP can also efficiently function to generate singlet oxygen in situ (ΦΔ≈20 %) and has appropriate topology and dimensions to interact with lipid membranes. The resulting rapid membrane insertion and sensitizing ability provide PTTP with a highly efficient antibacterial capability under a low light dose (0.6 J cm?2) toward Gram-negative bacteria E. coli, making it a remarkably efficient optically mediated antimicrobial agent.
Tetradentate platinum(II) complexes: Synthesis, photophysical properties, liquid crystalline characteristics and charge transport behaviour

, p. 398 - 406 (2019)
Three new tetradentate phosphorescent Pt(II) complexes (Pt6, Pt12 and Pt16) with half-disc molecule structure were designed and synthesized, which are based on tetradentate ligands with six alkoxyl chains on the periphery,

, p. 985 - 989 (2015)
The self-assembly of axial dipolar subphthalocyanine molecules in the presence of electric fields leads to uniaxially oriented columnar liquid crystalline materials that exhibit permanent polarization.
Partially stripped insulated nanowires: A lightly substituted hexa-peri-hexabenzocoronene-based columnar liquid crystal
Wang, Zhaohui,Watson, Mark D.,Wu, Jishan,Muellen, Klaus
, p. 336 - 337 (2004)
We present the facile preparation and characterization of the first "unwrapped" hexa-peri-hexabenzocoronene derivative, which forms a stable columnar liquid crystalline mesophase with a practically accessible isotropization temperature.
Efficient preparation of stereopure amphiphilic 1,2-amino alcohols by using preparative enantioselective HPLC
Kanai, Hayato,Yamada, Kuniyo,Kodama, Koichi,Ishida, Yasuhiro
, p. 295 - 305 (2021/11/22)
Chiral amphiphiles are useful for controlling the structures and properties of supramolecular assemblies, but their stereocontrolled synthesis is generally difficult, because their long alkyl chains tend to bring unfavorable effects on the solubility, rea
The liquid crystal Click procedure for oligothiophene-Tethered phthalocyanines-self-Assembly, alignment and photocurrent

A series of star-shaped liquid crystals (LCs) with a phthalocyanine donor core, oligothiophene antennae and fullerene acceptors have been successfully prepared. This hierarchical self-Assembly results in a nanosegregated helical donor-Acceptor-Antennae LC-system promoted by the recently discovered Click procedure. This model system reveals all photophysical prerequisites for energy conversion, charge generation and transport. Uniform amorphous thin films of 150 nm could be produced by bar-coating. Annealing did not only induce the formation of columns via the Click procedure but also partially homeotropically aligned the non-clearing sample in a sandwich geometry (ITO and Ag/MoO3). This has been confirmed by microscopic studies and the measurement of photocurrent, which increased by a factor of 300 after the annealing step.
