New self-assembling systems based on bola-type pyrimidinic surfactants

Supramolecular Systems Based on Novel Mono‐ and Dicationic Pyrimidinic Amphiphiles and Oligonucleotides: A Self‐Organization and Complexation Study

“…Pyrimidinic surfactants MPM, BPM, GPM-1 and GPM-2 were prepared according to the known protocol [61] , starting from 3-(5-bromopentyl)-3,6-dimethyluracil, 1,3-bis(5-bromopentyl)-6-methyluracil and 1,3-bis(5-bromopentyl)-5-decyl-6-methyluracil, respectively, followed by the substitution of bromide with diethylamine. The diethylamino-group was finally quaternized with n-decylbromide.…”

Thermal Behavior of Dodecylpyridinium-Based Surfactant Salts with Varied Anionic Constituent

“…Having this property and as well as ability to interact in different way, including some host-guest mechanisms, 1 synthetic catanionic amphiphilic systems are interesting from both, fundamental and practical viewpoint. The design of new materials, especially nanomaterials based on self-organization procedure has been one of the main focus in the field of supramolecular chemistry.…”

“…Besides this, such systems may provide information of the elementary mechanisms and functioning of their prototypes through biomimetics. 1 Exploration of new amphiphilic building blocks is an important task since this makes it possible to diversify supramolecular architectures and physicochemical properties of systems. 1 surfactant complexes in forms of stretched networks, 22 bind with three dimensional coordination polymers and anionic planar substances such as dyes, 17,23 naphthalene or benzenesulfonates.…”

Supramolecular systems based on cationic surfactants and amphiphilic macrocycles

“…In this case, the nature of the head groups is widely varied, in particular, via the functionalization of trimethylammonium (TMA) group with hydroxyalkyl substituents [24][25][26]; incor poration of cyclic and bicyclic fragments [27][28][29]; and variations in the nature of the charged atom, for exam ple, by passing from surfactants of the TMA series to triphenylphosphonium (TPP) derivatives [30]. Among the above listed surfactants, mono and dicationic (gemini) analogs are being investigated [31][32][33] A separate field of research is devoted to mono and dicationic surfactants, which contain "natural" fragments in their molecules, e.g., nucleotide bases, steroid residues, etc., and have various structures, including acyclic and macrocyclic analogs with spac ers of different length and different numbers of hydro phobic fragments [34][35][36][37][38][39][40][41].…”
