Four-armed biobased glycyrrhizic acid-tailored AIE fluorescent gelator

Self-assembled glycyrrhetinic acid derivatives for functional applications: a review

“…Conversely, TPE-4GL in 1,2-propanediol/water (2 : 8, v/v) formed small regular nanospheres and the fluorescence intensity achieved a maximum value at f w = 60%. 66 GA derivatives have also been used in tissue engineering. Wound healing is a complex process with three overlapping phases: inflammation, proliferation, and remodeling.…”

“…Chemically modifying GL with functional units has been highlighted in the design of a gelator with an aggregation-induced emission (AIE) feature. Taking TPE-4GL as an example, 66 four natural GLs play an important role in the hydrophilic feature, while the hydrophobic tetraphenylethene (TPE) makes TPE-4GL have AIE characteristics. After heating to a clear solution and instantly cooling to room temperature, stable opaque gels were obtained in DMSO/water (2 : 8, v/v) and 1,2-propanediol/water (2 : 8, v/v) with a minimum gelation concentration (MGC) of 23 and 19 mg mL −1 , respectively.…”

Triterpenoid Building Blocks for Functional Nanoscale Assemblies: A Review

“…Extensive research pursued over the last two decades on structurally and functionally different molecules has provided on-demand design of gelators with unique mechanical and material characteristics. The building blocks, including long-chain hydrocarbons, peptides, polyaromatics, heteroaromatics, steroids, , carbohydrates, − and phosphates, have been studied extensively in the literature. Even if not all amphiphilic molecules are gelators, amphiphilicity seems to be a common characteristic of a large number of LMWGs, regardless of the nature of the gels and the diversity of building blocks .…”
