چکیده
We report the first synthesis of a dendritic multicalixarene, featuring twenty-one calixarene units, which when adsorbed onto mica, forms regular assemblies which can then further aggregate to form larger clusters.

Requirements for Third Generation University: A Conceptual Review of Iranian Studies
Introduction: For more than a decade, Iranian researchers have been concerned about the third- generation university and have conducted various studies in this field. Collecting and analyzing the ideas presented in these studies may pave the way for finding a path for transformation into third-generation university. This study tries to introduce the requirements of moving Iranian universities t...
متن کاملPhotophysical properties of Newkome-type dendrimers in aqueous medium.
Newkome-type first, second and third generation dendrimers, having t-butyl (GB), ethyl (GE) and carboxylic (GA) end groups, were synthesized. A pyrene group, which can act as fluorescent sensor, was attached to the core of the dendrimers and their photophysical properties in aqueous solution were studied. These dendrimers were found to aggregate in aqueous solution, which manifested as an excim...
متن کاملLow-generation dendrimers with a calixarene core and based on a chiral C 2-symmetric pyrrolidine as iminosugar mimics
The preparation of low-generation dendrimers based on a simple calix[4]arene scaffold by insertion of the iminosugar-analogue C(2)-symmetric 3,4-dihydroxypyrrolidine is described. This methodology allows a rapid incorporation of a considerable number of iminosugar-like moieties in a reduced volume and in a well-defined geometry. The inclusion of alkali-metal ions (sodium and potassium) in the p...
متن کاملMagnetic hyperthermia and MRI relaxometry with dendrimer coated iron oxide nanoparticles
Introduction: Recently, some studies have focused on dendrimer nanopolymers as an MRI contrast agent or a vehicle for gene and drug delivery. Considering the suitable properties of these materials, they are appropriate candidates for coating iron oxide nanoparticles which are applied to magnetic hyperthermia. To the best of our knowledge, the novelty of this study is the inves...
متن کاملBinding interactions between the host cucurbit[7]uril and dendrimer guests containing a single ferrocenyl residue.
The stability of the inclusion complexes formed between the host cucurbit[7]uril and dendrimers containing a single ferrocene residue is strongly affected by the solution pH and the growth of the dendrimer, reaching its highest values on the second and third generation dendrimers, whereas no complex is formed with the first generation compound.
