Two novel gelators G1 and G2 based on naphthalene and cholesterol derivatives were synthesized and showed stable organogel formation in different solvents. G2 exhibited efficient fluorescence sensing for Fe3+ and Cu2+, and the self-assembly mechanism and ion response mechanism were further investigated. The detection limits of G2 for Fe3+ and Cu2+ were 8.2539 x 10-6 M and 9.1426 x 10-6 M, respectively. Additionally, a rapid fluorescence detection film for Fe3+ and Cu2+ was developed.
Two novel gelators G1 and G2 based on naphthalene and cholesterol derivatives were designed and synthesized, which could form stable organogel in different kind of solvents. Interestingly, G2 could act as an efficient fluorescent sensor for detection of Fe3+ and Cu2+, also the self-assembly mechanism and ion response mechanism were further studied. The detection limits of G2 for Fe3+ and Cu2+ are 8.2539 x 10-6 M and 9.1426 x 10-6 M, respectively. Besides, a rapid fluorescence detection film for Fe3+ and Cu2+ were also developed.
