Oligobisvelcraplex:  Self-Assembled Linear Oligomer by Solvophobic π−π Stacking Interaction of Bisvelcrands Based on Resorcin[4]arene

Bisvelcrand 3 based on resorcin[4]arene was obtained by a stepwise route, and the formation of oligobisvelcraplex 3 n by solvophobic π−π stacking interaction was observed. 1H NMR spectroscopic studies revealed that ΔG ⧧ pseudorotation of oligobisvelcraplex 3 n is 16.7 kcal mol-1 in C6D5NO2 solution....

Description
Summary:Bisvelcrand 3 based on resorcin[4]arene was obtained by a stepwise route, and the formation of oligobisvelcraplex 3 n by solvophobic π−π stacking interaction was observed. 1H NMR spectroscopic studies revealed that ΔG ⧧ pseudorotation of oligobisvelcraplex 3 n is 16.7 kcal mol-1 in C6D5NO2 solution. The pulsed field gradient spin−echo (PGSE) NMR experiment and VPO experiment showed that the number of aggregation (n) ranges from 7 to 10 in CHCl3 solution at 298 K. In high concentration, bisvelcrand 3 tends to form gels or fiber.
