The 1:1 dichloromethane and dimethylformamide solvates were found to be isostructural, and different to the typical bilayer structure often observed for p-t-butylcalix[4]arene solvates. The methanol solvate, in contrast, does form a bilayered structure but is also a 1:1 solvate, unlike the p-t-butylcalix[4]arene·2MeOH system. Lanthanoid complexation was investigated, resulting in the structural characterisation of two different DMF solvates of a 2:2 dimeric europium complex, Eu2(L–3H)2(DMF)4. A tetrazole derivative, 5,11,17,23-tetracyclohexyl-25,27-dihydroxy-26,28-bis(tetrazole-5-ylmethoxy)calix[4]arene, has been synthesised via the intermediate 5,11,17,23-tetracyclohexyl-25,27-dihydroxy-26,28-dicyanomethoxycalix[4]arene, with the latter compound being structurally characterised. Attempts to isolate lanthanoid clusters supported by the tetrazole derivative under conditions known to form Ln19 clusters with the p-t-butyl analogue were unsuccessful, resulting only in isolation of the ligand from the reaction mixture.

The complexes 4,4´-BPS@β-CD and 2,4´-BPS@β-CD were studied in solution by 1D and 2D NMR experiments. Calorimetric investigation by ITC evidenced that the β-CD host shows a greater affinity for 4,4´-BPS, with a 4,4´-BPS/2,4´-BPS selectivity ratio of 6.3. In the gas phase, CID MS experiments indicate that 4,4´-BPS has a higher kinetic barrier to escape from the β-CD cavity than the isomeric 2,4´-BPS. In the solid state, the 4,4´-BPS@β-CD and 2,4´-BPS@β-CD complexes form head-to-head dimers constituted by two β-CD macrocycles, with each β-CD hosting one BPS guest. The dimers of β-CD are sealed by H-bonding interactions involving exclusively the secondary OH groups. Finally, the formation of inclusion complexes between 4,4´-BPS or 2,4´-BPS and β-CD was also followed by FT-IR, DSC, and TGA analysis.

Their self-assemblies and photophysical properties were investigated by polarising optical microscope, differential scanning calorimetry, X-ray diffraction and scanning electron microscopy. Such compounds can self-assemble into honeycomb cylinder mesophases with Colhex∆/p6mm and Colsqu/p4mm lattices in their pure states as well as organogels with different morphologies in organic solvents. Their absorption spectra cover nearly the entire visible light range and their band gaps are relatively low. Tetrathiophene BTD based bolaamphilphiles (BT4/n ) with higher D/A ratios than the bisthiophene BTD bolaamphilphiles (BT2/n ) can self-assemble into more ordered nanostructures in both bulk states and solution. Both the absorption and emission peaks of BT4/n are strongly red shifted. The influence of the molecular conformation, the conjugated core length, as well as the D/A ratio on the self-assemble and photophysical characteristics of such D-A-D bolaamphiphiles are discussed.

These ligands have been successfully coordinated with trivalent lanthanide ions (europium, terbium, and lanthanum) forming [Ln(L)3](CF3SO3)3 complexes. The ligands act as effective antennae for Eu3+ and Tb3+ complexes, which exhibit the characteristic sensitised emission profiles. The ability of 1–3 to assemble into 1:3 M:L systems in solution was investigated using UV-Vis, fluorescence, and NMR. Finally, density functional calculations of the ground state La3+ complexes have been carried out and show similar geometry and coordination parameters to those with available crystallographic data. The facile and modular synthesis of these ‘clicked’ PDC-based ligands makes these compounds excellent candidates for luminescent supramolecular materials development.","PeriodicalId":22084,"journal":{"name":"Supramolecular Chemistry","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2021-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81038416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
