macrocycle structure influences its functional properties and, consequently, can provide new possibilities, among which are aggregation properties, water solubility, biocompatibility, stimuli response, biological activity, etc. Herein, we report synthesis of new resorcin[4]arene with N-methyl-d-glucamine groups on the upperrim and n-decyl chains on the lower rim, an investigation of its self-assembly
The syntheses and photoinduced deprotection reactions of calix[4]resorcinarene derivatives with pendant t-butyl ester moieties were examined. Calix[4]resorcinarenes, 1a–1h, were prepared by the condensation reaction of resorcinol with certain aldehydes in the presence of hydrochloric acid as a catalyst in ethanol at 80 °C for 30 min in good yields. The substitution reaction of 1a–1h with t-butyl bromoacetate using cesium carbonate as a base and tetrabutylammmonium bromide (TBAB) as a phase transfer catalyst was performed to afford the corresponding calix[4]resorcinarene derivatives, 2a–2h with pendant t-butyl ester groups. It was found that 2a, 2e, 2f, 2g, and 2h had film forming properties. The photo-induced deprotection reaction of calixarene derivatives 2a, 2e, 2f, 2g, and 2h was examined in the presence of bis-[4-(diphenylsulfonio)phenyl] sulfide (DPSP) as a photoacid generator in the film state upon UV irradiation for 5 min followed by heating at 170 °C. It was found that the deprotection reaction of the t-butyl ester groups of 2a, 2e, 2f, 2g, and 2h proceeded smoothly to produce the corresponding calixarene derivatives, 3a, 3e, 3f, 3g, and 3h with carboxylic acid groups, quantitatively.
amine‐based illicit and designerdrugs is addressed by nanomechanical recognition at the silicon–water interface. The methylamino moieties of different drugs are all first recognized by a single cavitand receptor through a synergistic set of weak interactions. The peculiar recognition ability of the cavitand is then transferred with high fidelity and robustness on siliconmicrocantilevers and harnessed
