- EXAMPLE 1 Preparation of gels from an equimolar mixture of conventional bis-ureas and functionalized in the presence of an apolar solvent - Influence of the spacer.
- Table 1 presents the results obtained for these various solutions.
- the Applicant believes that the functionalized bis-ureas could not form gels because of the steric hindrance of the macromolecular chains which prevents tubular self-assembly of functionalized bis-ureas; the equimolar mixture of conventional and functionalized bis-ureas containing identical spacers, that is to say mixtures EHUT / PIBUT (with a toluene spacer) and EHUTMB / PIBUTMB (with a trimethylbenzene spacer) does not form gels ; the equimolar mixture of conventional and functionalized bis-ureas containing different spacers, that is to say mixtures EHUT / PIBUX, EHUT / GDPUTMB, EHUTMB / PIBUT, EHUTMB / PIBUX, EHUX / PIBUT and EHUX / PIBUTMB, makes it possible to form stable gels.
- Figure 1 shows a photograph showing a solution of EHUTMB (left), PIBUX (right) and EHUTMB / PIBUX mixture (90% mol / 10 mol%) (in the middle) in dodecane (4g / Room temperature.
- FIG. 1 shows that the classic bis-urea EHUTMB is not soluble in dodecane (white precipitate) unlike PIBUX functionalized bis-urea which provides a homogeneous solution.
- the photograph also shows that the EHUTMB / PIBUX mixture (90 mol% / 10 mol%) of these bis-ureas containing complementary spacers (trimethylbenzene spacer for EHUTMB and xylene spacer for PIBUX) makes it possible to obtain 1) good solubilization.
- Gel formation is obtained by tubular self-assembly of bis-ureas in solution by means of intermolecular hydrogen bonds. However, depending on the polarity of the solvent, there may be competition between the formation of hydrogen bonds between the bis-ureas and the formation of hydrogen bonds between the bis-ureas and the solvent.
- the EHUTMB bis-urea ( Figure 2B, right) and PABUX ( Figure 2B, left) are each soluble in THF at a concentration of 100 g / L. However, these bis-urea solutions do not form a gel at room temperature; these solutions are liquid.
- the functionalized bis-urea PABUX, has made it possible to promote the solubilization of the conventional bis-urea EHUTMB in solvents which are unfavorable for the formation of gel by hydrogen bonds.
- the conventional bisurea EHTUMB is not soluble in apolar solvents having long alkyl chains such as dodecane.
- Functional bis-urea PIBUX is soluble in dodecane.

- Table 2 shows the results obtained for the various mixtures made as a function of the molar amount of functionalized bis-ureas (PIBUX) relative to the total molar amount of bis-ureas introduced into the mixture.
- PIBUX functionalized bis-ureas
- PIBUX improves the solubilization of EHUTMB in dodecane; in fact, when the composition mainly comprises PIBUX functionalised bis-ureas (> 70 mol in PIBUX in the mixture), a homogeneous liquid solution is obtained: the conventional and functionalized bis-ureas are solubilized in the medium.

- EHUTMB trimethylbenzene spacer
- PIBUX functionalized bis-ureas having a xylene spacer
- the IRFT analysis makes it possible to observe the absorption bands of the NHs of the urea functions.
- the NH bond resonates at different frequencies depending on whether it is bonded ( ⁇ 3400cm ⁇ 1 ) or not (> 3400cm ⁇ 1 ) by hydrogen bonding to another urea function.
- value of the ratio of the absorbances at 3330 and 3300cm is characteristic of their assembly structure: this ratio is of the order of 1.1 for the filamentary structure and the order of 1.3 for the tubular structure.
- the results presented in FIG. 4 show that for an EHUTMB / PIBUX mixture (50 ⁇ mol / 50 ⁇ mol), the NH absorption bands change shape when the temperature of the mixture is greater than or equal to approximately 70.degree.
- the gel / liquid transition temperature of the mixture EHUTMB / PIBUX (50% mol / 50 mol%) in toluene is thus about 70 ° C.
- the gel obtained by EHUTMB / PIBUX (50 mol / 50 mol) in toluene therefore remains stable when heated to temperatures not exceeding 70 ° C.
- the NH absorption bands change shape when the temperature of the mixture is greater than or equal to about 50 ° C.
- the gel / liquid transition temperature of the EHUTMB / PIBUX mixture (90 ⁇ mol / 10 mol) in toluene is therefore about 50.degree.
- the gel obtained with EHUTMB / PIBUX (90% mol / 10 mol%) in toluene therefore remains stable when heated at temperatures not exceeding 50 ° C.
- Figure 5 shows the evolution of the ratio of the absorbances at 3330 and 3300cm -1 as a function of the temperature of a mixture EHUTMB / PIBUX (90 ⁇ mol / 10 moL) This representation confirms that the gel / liquid transition temperature for this mixture is about 50 ° C. 5.2 in dodecane
- EHUTMB / PIBUX compositions (% .mol /% mol.): 90/10; 30/70; 40/60; 60/40 and 70/30.

- the mixture of conventional bis-ureas having a trimethylbenzene spacer (EHUTMB) and functionalized bis-ureas having a xylene spacer (PIBUX) was studied in toluene, solvent in which these two bisureas are soluble, at a total concentration of bis-ureas in toluene of 2 g / L.
- the aim is to evaluate the temperature range over which the EHUTMB / PIBUX mixture provides a stable gel. For this, the relative viscosity of various EHUTMB / PIBUX compositions was measured at 20 ° C, 40 ° C, 60 ° C and 80 ° C.
- a solution comprising only EHUTMB is very viscous whatever the temperature (20, 40, 60 or 80 ° C); a solution comprising only PIBUX is moderately viscous at 20 ° C and becomes less and less viscous when the temperature is increased to 80 ° C; a solution comprising a mixture PIBUX / EHUTMB has high viscosities for temperatures up to 60 ° C, in particular an equimolar mixture PIBUX / EHUTMB is stable up to a temperature of 67 ° C.
