MOLECULAR TECTONICS - DESIGN, SYNTHESIS AND STRUCTURAL-ANALYSIS OF A MOLECULAR NETWORK-BASED ON INCLUSION PROCESSES USING A DOUBLY FUSED P-ISOPROPYLCALIX[4]ARENE

The synthesis of a hollow molecular module (koiland) possessing two di vergent cavities was achieved by double fusion of two p-isopropylcalix [4]arenes in cone conformation by two silicon atoms. The formation of either a discrete binuclear inclusion complex in the presence of CH2Cl 2 acting as stopper or of an infinite 1-D inclusion network (koilate) in the presence df hexadiyne acting as connector was demonstrated in t he solid state by single-crystal diffraction studies. The inclusion ne twork was based on the interconnection of consecutive koilands by conn ector molecules.
