Abstract

The invention discloses a multi-stimulation responsive stigmasterol derivative low-molecular-mass gelator, organic gel and preparation methods of the low-molecular-mass gelator and the organic gel. The stigmasterol-based glycine ferrocene amide gelator is prepared through a three-step synthesis reaction including esterification, BOC removal and amidation for the first time with stigmasterol with arigid framework used as a gelator construction parent, glycine used as a linking arm and ferrocene containing an oxidation activity group as a reaction group, and the problem of lack of research on construction of a super-molecular gel system with stigmasterol and ferrocene derivatives as gelators in the prior art is solved. An organic gel material of the gelator has properties of thixotropy, ultrasonic response, thermal response and alcohol solvent stimulation response besides oxidation stimulation response expected to be obtained through introduction of the ferrocene group, and the gel is expected to have potential value in the aspects of sensors, solvent recognition and the like.

Description

technical field [0001] The invention belongs to the field of supramolecular self-assembly, and relates to a stigmasteryl glycine ferrocenyl amide small-molecule gel factor, an organogel and a preparation method thereof. Background technique [0002] Small molecule gel refers to a viscoelastic, semi-solid, semi-liquid, self-supporting soft substance formed by organic small molecule compounds with definite structure and molecular weight in a certain solvent and under certain conditions. Small molecule gels belong to physical gels, which are supramolecular three-dimensional network structures formed under weak non-covalent bond interactions such as hydrogen bonds, van der Waals forces, π-π stacking, electrostatic interactions, and hydrophobic interactions. Due to this weak interaction force, small molecule gels can easily complete some reversible phase transitions under certain conditions, forming intelligent phase change materials with reversible stimulus responses. Small mole...
