Abstract
Bisvelcrand 3 based on resorcin[4]arene was obtained by a stepwise route, and the formation of oligobisvelcraplex 3(n) by solvophobic pi-pi stacking interaction was observed. H-1 NMR spectroscopic studies revealed that DeltaG(pseudorotation)(double dagger) 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.
